DESCRIPTION  
The LM5110 Dual Gate Driver replaces industry  
standard gate drivers with improved peak output  
current and efficiency. Each “compound” output driver  
stage includes MOS and bipolar transistors operating  
in parallel that together sink more than 5A peak from  
5A sink/3A Source Current Capability  
Two Channels can be Connected in Parallel to  
Double the Drive Current

Combining  
the  
unique  
characteristics of MOS and bipolar devices reduces  
drive current variation with voltage and temperature.  
Separate input and output ground pins provide  
Negative Drive Capability allowing the user to drive  
MOSFET gates with positive and negative VGS  
voltages. The gate driver control inputs are  
referenced to a dedicated input ground (IN_REF).  
The gate driver outputs swing from VCC to the output  
ground VEE which can be negative with respect to  
IN_REF. The ability to hold MOSFET gates off with a  
negative VGS voltage reduces losses when driving  
low threshold voltage MOSFETs often used as

DETAILED OPERATING DESCRIPTION  
LM5110 dual gate driver consists of two independent and identical driver channels with TTL compatible logic  
inputs and high current totem-pole outputs that source or sink current to drive MOSFET gates. The driver output  
consist of a compound structure with MOS and bipolar transistor operating in parallel to optimize current  
capability over a wide output voltage and operating temperature range. The bipolar device provides high peak  
current at the critical threshold region of the MOSFET VGS while the MOS devices provide rail-to-rail output  
swing. The totem pole output drives the MOSFET gate between the gate drive supply voltage VCC and the power  
ground potential at the VEE pin.  
The control inputs of the drivers are high impedance CMOS buffers with TTL compatible threshold voltages. The  
negative supply of the input buffer is connected to the input ground pin IN_REF. An internal level shifting circuit  
connects the logic input buffers to the totem pole output drivers. The level shift circuit and separate input/output  
ground pins provide the option of single supply or split supply configurations. When driving MOSFET gates from  
a single positive supply, the IN_REF and VEE pins are both connected to the power ground. The LM5110 pinout  
was designed for compatibility with industry standard gate drivers in single supply gate driver applications. Pin 1  
(IN_REF) on the LM5110 is a no-connect on standard driver IC's. Connecting pin 1 to pin 3 (VEE) on the printed  
circuit board accommodates the pin-out of both the LM5110 and competitive drivers.  
The isolated input/output grounds provide the capability to drive the MOSFET to a negative VGS voltage for a  
more robust and reliable off state. In split supply configuration, the IN_REF pin is connected to the ground of the  
controller which drives the LM5110 inputs. The VEE pin is connected to a negative bias supply that can range  
from the IN-REF as much as 14V below the VCC gate drive supply. The maximum recommended voltage  
difference between VCC and IN_REF or between VCC and VEE is 14V. The minimum voltage difference between  
VCC and IN_REF is 3.5V.  
Enhancement mode MOSFETs do not inherently require a negative bias on the gate to turn off the FET.  
However, certain applications may benefit from the capability of negative VGS voltage during turn-off including:  
1. when the gate voltages cannot be held safely below the threshold voltage due to transients or coupling in the  
printed circuit board.  
2. when driving low threshold MOSFETs at high junction temperatures  
3. when high switching speeds produce capacitive gate-drain current that lifts the internal gate potential of the  
MOSFET  
The two driver channels of the LM5110 are designed as identical cells. Transistor matching inherent to integrated  
circuit manufacturing ensures that the ac and dc performance of the channels are nearly identical. Closely  
matched propagation delays allow the dual driver to be operated as a single driver if inputs and output pins are  
connected. The drive current capability in parallel operation is 2X the drive of either channel. Small differences in  
switching speed between the driver channels will produce a transient current (shoot-through) in the output stage  
when two output pins are connected to drive a single load. The efficiency loss for parallel operation has been  
characterized at various loads, supply voltages and operating frequencies. The power dissipation in the LM5110  
increases by less than 1% relative to the dual driver configuration when operated as a single driver with inputs  
and outputs connected.  
An Under-voltage lockout (UVLO) circuit is included in the LM5110, which senses the voltage difference between  
VCC and the input ground pin, IN_REF. When the VCC to IN_REF voltage difference falls below 2.7V both driver  
channels are disabled. The driver will resume normal operation when the VCC to IN_REF differential voltage  
exceeds approximately 2.9V. UVLO hysteresis prevents chattering during brown-out conditions.  
The Shutdown pin (nSHDN) is a TTL compatible logic input provided to enable/disable both driver channels.  
When nSHDN is in the logic low state, the LM5110 is switched to a low power standby mode with total supply  
current less than 25 µA. This function can be effectively used for start-up, thermal overload, or short circuit fault  
protection. It is recommended that this pin be connected to VCC when the shutdown function is not being used.  
The shutdown pin has an internal 18μA current source pull-up to VCC  
.
The input pins of non-inverting drivers have an internal 18μA current source pull-down to IN-REF. The input pins  
of inverting driver channels have neither pull-up nor pull-down current sources.  
The LM5110 is available in dual non-inverting (-1), dual inverting (-2) and the combination inverting plus non-  
inverting (-3) configurations. All three configurations are offered in the SOIC-8 and WSON-10 plastic packages.

Layout Considerations  
Attention must be given to board layout when using LM5110. Some important considerations include:  
1. A Low ESR/ESL capacitor must be connected close to the IC and between the VCC and VEE pins to support  
high peak currents being drawn from VCC during turn-on of the MOSFET.  
2. Proper grounding is crucial. The drivers need a very low impedance path for current return to ground  
avoiding inductive loops. The two paths for returning current to ground are a) between LM5110 IN-REF pin  
and the ground of the circuit that controls the driver inputs, b) between LM5110 VEE pin and the source of the  
power MOSFET being driven. All these paths should be as short as possible to reduce inductance and be as  
wide as possible to reduce resistance. All these ground paths should be kept distinctly separate to avoid  
coupling between the high current output paths and the logic signals that drive the LM5110. A good method  
is to dedicate one copper plane in a multi-layered PCB to provide a common ground surface.  
3. With the rise and fall times in the range of 10 ns to 30 ns, care is required to minimize the lengths of current  
carrying conductors to reduce their inductance and EMI from the high di/dt transients generated by the  
LM5110.  
4. The LM5110 SOIC footprint is compatible with other industry standard drivers. Simply connect IN_REF pin of  
the LM5110 to VEE (pin 1 to pin 3) to operate the LM5110 in a standard single supply configuration.  
5. If either channel is not being used, the respective input pin (IN_A or IN_B) should be connected to either  
IN_REF or VCC to avoid spurious output signals. If the shutdown feature is not used, the nSHDN pin should  
be connected to VCC to avoid erratic behavior that would result if system noise were coupled into a floating  
’nSHDN’ pin.  
Thermal Performance  
INTRODUCTION  
The primary goal of thermal management is to maintain the integrated circuit (IC) junction temperature (TJ) below  
a specified maximum operating temperature to ensure reliability. It is essential to estimate the maximum TJ of IC  
components in worst case operating conditions. The junction temperature is estimated based on the power  
dissipated in the IC and the junction to ambient thermal resistance θJA for the IC package in the application board  
and environment. The θJA is not a given constant for the package and depends on the printed circuit board  
design and the operating environment.  
DRIVE POWER REQUIREMENT CALCULATIONS IN LM5110  
The LM5110 dual low side MOSFET driver is capable of sourcing/sinking 3A/5A peak currents for short intervals  
to drive a MOSFET without exceeding package power dissipation limits. High peak currents are required to  
switch the MOSFET gate very quickly for operation at high frequencies.

Q2  
The schematic above shows a conceptual diagram of the LM5110 output and MOSFET load. Q1 and Q2 are the  
switches within the gate driver. RG is the gate resistance of the external MOSFET, and CIN is the equivalent gate  
capacitance of the MOSFET. The gate resistance Rg is usually very small and losses in it can be neglected. The  
equivalent gate capacitance is a difficult parameter to measure since it is the combination of CGS (gate to source  
capacitance) and CGD (gate to drain capacitance). Both of these MOSFET capacitances are not constants and  
vary with the gate and drain voltage. The better way of quantifying gate capacitance is the total gate charge QG  
in coloumbs. QG combines the charge required by CGS and CGD for a given gate drive voltage VGATE  
.

As an example, consider the MOSFET MTD6N15 whose gate charge specified as 30 nC for VGATE = 12V.  
The power dissipation in the driver due to charging and discharging of MOSFET gate capacitances at switching  
frequency of 300 kHz and VGATE of 12V is equal to  
PDRIVER = 12V x 30 nC x 300 kHz = 0.108W.  
If both channels of the LM5110 are operating at equal frequency with equivalent loads, the total losses will be  
twice as this value which is 0.216W.  
In addition to the above gate charge power dissipation, - transient power is dissipated in the driver during output  
transitions. When either output of the LM5110 changes state, current will flow from VCC to VEE for a very brief  
interval of time through the output totem-pole N and P channel MOSFETs. The final component of power  
dissipation in the driver is the power associated with the quiescent bias current consumed by the driver input  
stage and Under-voltage lockout sections.  
Characterization of the LM5110 provides accurate estimates of the transient and quiescent power dissipation  
components. At 300 kHz switching frequency and 30 nC load used in the example, the transient power will be 8  
mW. The 1 mA nominal quiescent current and 12V VGATE supply produce a 12 mW typical quiescent power.  
Therefore the total power dissipation  
PD = 0.216 + 0.008 + 0.012 = 0.236W.  
We know that the junction temperature is given by  
TJ = PD x θJA + TA  
Or the rise in temperature is given by  
TRISE = TJ TA = PD x θJA  
For SOIC-8 package θJA is estimated as 170°C/W for the conditions of natural convection.  
Therefore TRISE is equal to  
TRISE = 0.236 x 170 = 40.1°C  
For WSON-10 package, the integrated circuit die is attached to leadframe die pad which is soldered directly to  
the printed circuit board. This substantially decreases the junction to ambient thermal resistance (θJA). θJA as low  
as 40°C/W is achievable with the WSON10 package. The resulting TRISE for the dual driver example above is  
thereby reduced to just 9.5 degrees.  
CONTINUOUS CURRENT RATING OF LM5110  
The LM5110 can deliver pulsed source/sink currents of 3A and 5A to capacitive loads. In applications requiring  
continuous load current (resistive or inductive loads), package power dissipation, limits the LM5110 current  
capability far below the 5A sink/3A source capability. Rated continuous current can be estimated both when  
sourcing current to or sinking current from the load. For example when sinking, the maximum sink current can be  
calculated as  
T (MAX) - T  
J
A
I
(MAX) :=  
SINK  
q
JA  
· R (ON)  
DS  
where  
RDS(on) is the on resistance of lower MOSFET in the output stage of LM5110  
Consider TJ(max) of 125°C and θJA of 170°C/W for an SO-8 package under the condition of natural convection  
and no air flow. If the ambient temperature (TA) is 60°C, and the RDS(on) of the LM5110 output at TJ(max) is  
2.5, this equation yields ISINK(max) of 391mA which is much smaller than 5A peak pulsed currents.  
Similarly, the maximum continuous source current can be calculated as
