Brief functional Description
The FAN7093_F085 is an integrated high current half bridge for
electric motor drive applications. It contains one P-channel high-
side MOSFET and one N-channel low-side MOSFET with an
integrated control IC in one package. With the P-channel high-
side switch the need for a charge pump is eliminated and
therefore minimizing EMI. Pins IN and ꢀꢁꢂ are logic level inputs
and control the half bridge outputs. The diagnostic current output
pin IS outputs a proportional current through the half bridge
MOSFETS. The IS pin output represents current for either the P-
Chan or the N-Chan depending on which is active. The part is
protected against short to Battery or ground, over current, over-
temperature, over voltage and under voltage. The
FAN7093_F085 provides a cost optimized solution for protected
high current PWM motor drives with very low board space
consumption.

Block Diagram
The FAN7093_F085 is a high current half-bridge and contains three separate chips in one package:
One P-channel high-side MOSFET and one N-channel low-side MOSFET together with a control IC.
All three chips are mounted on one common lead frame, using chip on chip and chip by chip
technology. The power FETs are vertical MOS transistors to ensure minimum on state resistance.
Using a P-channel high-side switch eliminates a charge pump and reduces EMI. A microcontroller is
able to control the logic level inputs IN and ꢀꢁꢂ of the half-bridge. The diagnostic pin IS is a current
output stage which delivers a proportional current through the P-channel and N-channel MOSFETS
depending on which is being activated with IN/ꢀꢁꢂ pin forcing conditions. In case of a short to
VBATT or ground the IS pin acts as an error Flag, which can be detected as a logic high level through
an attached microcontroller. In an over current situation the control IC turns off the MOSFETS and
retries to turn them back on after a cool down time of typical 140us. The control IC protects the
MOSFETS also against over voltage, under voltage and over temperature. The dead time to prevent
shoot through between P- and N- channel MOSFET is generated by the control IC too. The slew rate of
the outputs can be adjusted through an external resistor connected to the SR pin. The FAN7093_F085
can be combined with other FAN7093_F085 to form Full-bridge and also 3-phase drive configurations.

Note 1: Not subject to production test
7.2 Protection Functions
The device provides integrated protection functions. These are designed to prevent IC destruction
under fault conditions described in the data sheet. Fault conditions are considered as “outside” normal
operating range. Protection functions are not to be used for continuous or repetitive operation, with the
exception of the current limitation. In a fault condition the FAN7093_F085 will apply the highest slew
rate possible independent of the connected slew rate resistor. Over voltage, over temperature and over
current are indicated by a fault current flag IIS(LIM) at the IS pin. The following describes the protection
functions are listed in order of their priority. Over voltage lock out overrides all other error modes.
7.2.1 Over voltage Lock Out
To assure a high immunity against over voltage conditions like load dump, the device turns off the
low-side MOSFET and turns on the high-side MOSFET when the supply voltage exceeds the over
voltage protection level VOV(OFF). The control IC returns to normal operation 120us after the supply
voltage decreases below the over voltage lock out level VOV(ON) . In H-bridge configuration, this
behavior of the FAN7093_F085 will lead to freewheeling in high-side during over voltage. If the load
current exceeds 90A in over voltage lock out, the IC turns off the high side driver and latches this state.
7.2.2 Under voltage Shut Down
To avoid uncontrolled motion of for example a driven motor at low voltages, the control IC will turn
off all MOSFETS, when the supply voltage drops below the turn-off voltage VUV(OFF). The control IC
returns to normal operation when the supply voltage rises above the turn-on voltage VUV(ON)
.
7.2.3 Over temperature Protection
The FAN7093_F085 is protected against over temperature by an integrated temperature sensor in the
control IC. Over temperature is turning off both output stages. This state is latched until the device is
reset by a low signal with a minimum pulse length of treset at the ꢀꢁꢂ pin, assuming the control IC
temperature decreased by at least the thermal hysteresis Repetitive use of the over temperature
protection impacts lifetime.
7.2.4 Current Limitation
The current is measured in both MOSFETS of the FAN7093_F085. As soon as the current is reaching
the limit ICL, the low- or high-side MOSFET is deactivated and the other MOSFET activated for tCLS
.
During that time changes at the IN pin are ignored. However, the ꢀꢁꢂ pin can still be used to turn off
both MOSFETs. After time tCLS the MOSFETS return to their initial setting. The error signal at the IS
pin is reset after 2 * t CLS. Unintentional triggering of the current limit circuitry through short current
spikes (e.g. inflicted by EMI coming from the motor) is suppressed by an internal filter. Reaction delay
time of the filter circuitry is affecting the current limit level ICL depending on slew rate of the load

current dI/dt.
Figure 4 Timing Diagram Current Limitation (Inductive Load)
In combination with a typical inductive load, such as a motor, this results in a switched mode current
limitation. This method of limiting the current has the advantage of greatly reduced power dissipation
in the FAN7093_F085 compared to driving the MOSFET in linear mode. Therefore it is possible to
use the current limitation for a short time without exceeding the maximum allowed junction
temperature (e.g. for limiting the inrush current during motor start up). However, the regular use of the
current limitation is allowed as long as the specified maximum junction temperature is not exceeded.
Exceeding this temperature can reduce the lifetime of the device.
7.2.5 Short Circuit Protection
The device is short circuit protected against
• output shorted to ground
• output shorted to battery voltage
• short circuit of load
The short circuit protection is a combination of current limit and over-temperature shut down of the
device

7.3 Control and Diagnostics
7.3.1 Input Circuit
The gate drivers for the MOSFETS are controlled through inputs IN and ꢀꢁꢂ and are TTL/CMOS
compatible Schmitt triggers with hysteresis. Setting theꢃꢀꢁꢂ pin to high enables the device. In this
condition one of the two power MOSFETS is turned on depending on the input level of the IN pin. To

deactivate both switches, the ꢀꢁꢂ pin has to be set to low. No external driver is needed. The
FAN7093_F085 can interface directly with a microcontroller, as long as the maximum ratings are not
exceeded.
7.3.2 Dead Time Generation
The dead time is generated on the control IC to prevent shoot through between the power MOSFETS.
The dead time is almost independent of the selected slew rate in order to reach a high PWM frequency
of 60kHz
7.3.3 Adjustable Slew Rate
In order to optimize electromagnetic emission, the switching speed of the MOSFETs is adjustable by
an external resistor. The slew rate pin SR allows the user to optimize the balance between emission
and power dissipation within the application by connecting an external resistor RSR to GND. If the SR
pin is open by design or if the intermittent disconnect happens, the slew rate is set to the value shown
in table on page 8 rows 7.1.1, 7.1.9.
7.3.4 Status Flag Diagnostic with Current Sense Capability
The status pin IS is used as a combined current sense and error flag output. In normal operation
(current sense mode), a current source, in the control IC is connected to the status pin, which delivers a
current proportional to the forward load current flowing through the active high-side or low-side
MOSFET. Current flow in the reverse direction cannot be detected except for a marginal leakage
current IIS(LK). The external resistor RIS determines the voltage per output current. The current sense
ratio is 1/8500 (see table on page 15 for details). In case of a fault condition the status output is
connected to a current source which is independent of the load current and provides IIS(lim). The
maximum voltage at the IS pin is determined by the choice of the external resistor and the supply
voltage. In case of current limitation the IIS(lim) is activated for 2 * tCLS

Counterfeiting of semiconductor parts is a growing problem in the industry. All manufactures of semiconductor products are experiencing counterfeiting of their
parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed
application, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the
proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild
Distributors who are listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild
Distributors are genuine parts, have full traceability, meet Fairchild’s quality standards for handing and storage and provide access to Fairchild’s full range of
up-to-date technical and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address and
warranty issues that may arise. Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is
committed to combat this global problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.
