NCP392ARFCCT1G

Adjustable Front End  Overvoltage Protection  Controller with Protected  Vbus Output 监控电路 100V OVP

The NCP392ARFCCT1G NCP392A is an overvoltage front end protection and be able to disconnect the systems from its output pin in case wrong input operating conditions are detected, up to +28 V. Due 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 external resistor bridge is used (A version).

At power up (EN pin = low level), the Vout turns on tstart time after internal timer elapsed.

A LDO, internally connected on IN pin, provided a protected output voltage even if an over voltage is present on IN pin.
