NIS5132
Green 3.6A 12V RESETTABLE ELECTRONIC FUSE
Description
The NIS5132 is a self-protected resettable electronic fuse designed
for consumer applications such as hard disk drives, to industrial
applications to enhance system reliability against catastrophic and
shutdown failures.
To support a wide range of demanding applications, the design has
been optimized to operate over the supply range of 9.0V to 18V. For
robustness and protections, the device integrates a low Rdson
NMOS buffer power device along with an undervoltage lockout,
overvoltage clamp, a current limit, a dv/dt control and a thermal
shutdown circuits. The overvoltage circuit limits the output voltage
without shutting the device down to allow the load to continue
operating during over voltage. Thermal shutdown can be either
latching type (NIS5132MN1) or auto-retry type (NIS5132MN2).

Function
Ground pin
Internal NMOS power device turn-on time adjustment pin:
If this pin is is left unconnected, the internal capacitor ensures the turn-on ramp is over a period of
2ms typical. If an additional delay is required, connect a capacitor from this pin to the ground.
Tri-state bi-directional interface pin:
The output can be disabled by pulling this pin to ground through an open drain or an open collector.
Additionally, this pin output goes to an intermediate state to indicate that the device is in thermal
shutdown state. This pin can also be connected together with other NIS5132 devices to cause a
system-wide simultaneous shutdown during thermal events.
Current limit setting pin:
A resistor between Source pins and this pin sets the overload and short-circuit current limit
thresholds.
No connect
The internal NMOS power device’s Source pins:
These pins are the Source of internal power device and also the output terminal of the electronic
fuse
