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.
Pin Assignments
(Top View)
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 R
DS(ON)
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).
