MARKING  
This chip includes a time delay for sequencing applications. It has a  
dual function OVLO pin that allows multiple units to be ganged  
together for simultaneous turn−on and shutdown, allowing units to be  
operated in parallel. It allows for user selectable undervoltage and  
overvoltage lockout levels. Its unique current limit circuit allows for  
adjustable current limit levels with no external power resistor. An  
internal temperature limiting circuit greatly increases the reliability of  
this device.

Function  
Description  
1
OVLO  
The overvoltage shutdown point is programmed by a resistor from this pin to the V supply. When  
CC  
tied together with other devices, this pin also communicates a shutdown state due to undervoltage  
and overtemperature reasons. All devices connected will simultaneously shutdown. Startup for this  
condition may be simultaneous or sequenced.

UVLO  
A resistor from V to the UVLO pin adjusts the voltage at which the device will turn on.  
CC  
Enable/Timer  
A high level signal on this pin allows the device to begin operation. Connection of a capacitor will  
delay turn on for timing purposes. A low input signal inhibits the operation, and communicates to any  
other paralleled devices (via the OVLO pin) to shutdown. This signal can also be used to reset the  
thermal latch.  
Ground

C
charge  
An external capacitor is required from this pin to the source pin. This is the storage capacitor for the  
internal charge pump. A small internal capacitor is included for noise filtering.

ILIMIT  
A resistor (RLIMIT) tied from this pin to the source pin sets the current limit level.  
A high impedance signal on this pin indicates that the power device is conducting.

OPERATING DESCRIPTION  
Operation  
reach the current limit threshold, or is shutdown due to an  
overvoltage, undervoltage or thermal fault. Both the UVLO  
and OVLO circuits incorporate hysteresis to assure clean  
turn−on and turn−offs with no chatter. The thermal latching  
circuit will require the input power to be recycled to resume  
operation after a fault. The current limit is always active, so  
any transient or overload will always be limited.  
The NIS5102 has a variety of shutdown and protection  
features that make this part extremely versatile as well as  
rugged. For the unit to operate, the input voltage must be  
within the operating range of the part which is set by the  
UVLO and OVLO bias resistors. The enable must also be  
high for operation. Current and thermal limit circuits  
constantly monitor the operation and will protect the unit if  
either of these parameters exceeds its preset limit.  
Circuit Description  
An additional shutdown method, is the use of the OVLO  
pin, which can be tied in parallel. This allows multiple units  
to be either operated in parallel, and will shutdown and turn  
on simultaneously for any fault other than an overvoltage, or  
it allows these hot plug devices to control independent loads,  
and shutdown and turn on simultaneously.  
Enable/Timer  
The enable/timer pin can function either as a direct enable  
pin, or as a time delay. In the enable mode, an open collector  
device is connected to this pin. When the device is in its low  
impedance mode, this pin is low and the operation of the chip  
is disabled. If a time delay is required, a capacitor is added  
to this pin. Figure 17 shows the equivalent circuit for the  
enable.

Figure 17. Enable/Timer Circuit  
If a capacitor is added without an open collector device,  
the turn on will be delayed from the time at which the UVLO  
voltage is reached. If an open collector device is also used,  
the delay will start from the time that it goes into its high  
impedance state. The capacitor is charged by an internal  
current source.

SENSEFET reaches around 90% of the internal charge  
pump output voltage, the power good will change its state  
from low impedance to high impedance but only after the  
power good delay has elapsed. Figure 10 shows the power  
good behavior during the startup of the NIS5102 device, an  
There is an inherent delay in the turn on of the hot plug  
device, due to the method of gate drive used. The gate of the  
power FET is charged through a high impedance resistor,  
and from the time that the gate starts charging until the time  
that it reaches its threshold voltage, there will be no  
conduction. Once the gate reaches its threshold voltage, the  
output current will begin a controlled ramp up phase.  
This delay will be added to any timing delay due to the  
enable/timer circuit.

CC  
The power good will change its state from high impedance  
to low impedance in the event of any fault condition such as  
short circuit and overvoltage.  
Undervoltage Lockout  
The UVLO circuit holds the chip off when the input  
voltage is less than the turn−on limit. It includes internal  
hysteresis to assure clean on/off switching. An internal  
divider sets the turn−on voltage level at 16 V. This voltage  
can be reduced by adding an external resistor from the

Overvoltage Lockout and Parallel Shutdown  
The overvoltage lockout (OVLO) is a dual function pin.  
This pin will normally be biased somewhere between  
ground and the input voltage, due to an internal voltage  
divider which sets the turn−off voltage level at 22 V. This  
voltage level can be reduced by adding an external resistor

Temperature Limit  
The theoretical equation for the OVLO turn−on voltage is:  
The temperature limit circuit senses the temperature of the  
Power FET and removes the gate drive if the maximum level  
is exceeded. For the auto−retry device, there is a nominal  
hysteresis of 40°C for this circuit. After a thermal shutdown,  
the device will automatically restart when the temperature  
drops to a safe level as determined by the hysteresis. The  
latching thermal circuit can be reset either by recycling the  
input power, or by toggling the enable signal.

CC  
To reduce nuisance tripping due to transients and noise  
spikes, a capacitor may be added from the OVLO pin to  
ground. This will create a low pass filter with a cutoff  
frequency of f. The required capacitance on this pin is:  
A short circuit condition is one in which the SENSEFET  
is not fully enhanced, and is therefore in a high impedance  
mode of operation. In this case there are many hundreds of  
millivolts across the drain to source pins of the SENSEFET.  
This occurs when the output sees a very low impedance short  
as well as when the capacitor is charging at turn on. In both  
cases there are several volts or more across the FET.  
An overload condition is one in which the SENSEFET is  
still fully enhanced and the drain to source voltage is the  
product of the drain current and the on resistance of the FET.  
The sense voltage out of the SENSEFET has a different  
relation to the drain current in these two conditions. The  
difference in current limit levels for these two cases is called  
DI, where:

pull it low, whenever the device is disabled due to any fault  
other than an Overvoltage condition. An enable pin  
shutdown is not considered a fault and will not cause a  
common shutdown. This feature allows multiple units to  
turn on and off simultaneously by tying the OVLO pins  
together in parallel. This can be used for operating several  
hot plug devices in parallel, or for use with separate loads,  
when all devices need to startup and shutdown  
simultaneously.

For this equation, V is the reference voltage of the  
where “ILimit” is the desired short circuit ILimit value, and  
R is the programming resistor from the ILimit pin to the  
ILimit  
ref  
current limit circuit, and R  
is the on resistance of the  
DSon  
SENSEFET. For more information on this, see application  
note AND8140/D, “SMART HotPlugt Current Limit  
Function”.  
This inherent property of the SENSEFET allows for  
simple dual level current limiting, in which a short circuit  
condition will see a lower level of limiting than will an  
overload. This operation will exist in start up as well as under  
normal operation, so the device will be able to differentiate  
between a short and an overload.  
As with all SMART HotPlug devices, the current limit will  
never shutdown the device. Only the thermal limit will stop  
the flow of current to the load. Once the current is stopped due  
to the thermal limit, it will remain off until input power is  
recycled for the latching version, or it will continuously retry  
to start again if it is the auto−retry version.  
The ILimit graph shown in Figure 5 was generated from  
the data of the ILimit characterization, the formula for the  
short circuit curve is:  
source pin.  
Turn−on Surge  
During the turn−on event, there is a large amount of  
energy dissipated due to the linear operation of the power  
device. The energy rating is the amount of energy that the  
device can absorb before the thermal limit circuit will shut  
the unit down. This is very important specially for the latch  
off device as it determines the maximum load capacitance  
that the device can charge before the thermal limit shuts the  
device down. The calculation of this is not very simple as it  
depends on several factors such as the input voltage (Vin),  
load capacitance (CL), current limit settings (ILimit) and  
device’s thermal transient response, therefore, it is  
recommended to do lab evaluations for these purposes.  
Figure 20 shows the device’s thermal transient response for  
minimum pad.
