NUS6189MN
Low Profile Overvoltage
Protection IC with
Integrated MOSFET
This device represents a new level of safety and integration by
combining an overvoltage protection circuit (OVP) with a 30 V
P ? channel power MOSFET, a low V CE(SAT) transistor, and low
R DS(on) power MOSFET or charging. The OVP is specifically
designed to protect sensitive electronic circuitry from overvoltage
transients and power supply faults. During such events, the IC quickly
disconnects the input supply from the load, thus protecting it. The
integration of the additional transistor and power MOSFET reduces
layout space and promotes better charging performance.
The IC is optimized for applications that use an external AC ? DC
adapter or a car accessory charger to power a portable product or
