NCP392C Datasheet, PDF (1/10 Pages) ON Semiconductor – Adjustable Front End Overvoltage Protection Controller

NCP392C
Adjustable Front End
Overvoltage Protection
Controller with Protected
Vbus Output
The NCP392C is an overvoltage front end protection controller and
is able to disconnect the systems from its output pin in case wrong
input operating conditions are detected, up to +28 V. Thanks to this
device using internal NMOS, no external device is necessary, reducing
the system cost and the PCB area of the application board.
Internal OVLO threshold is available, or can be adjusted if an
external resistor bridge is used.
At power up (EN pin = low level), the Vout turns on tstart time after
internal timer elapsed.
The NCP392C features an ACOK pin that indicates faulty
condition.
