NCP392B: Adjustable front end Overvoltage Protection Controller with protected Vbus output and input spike up to 100 V compliant

The NCP392 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. 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 external resistor bridge is used (A version). At power up (ENpin= low level), the Vout turns on tstart time after internal timer elapsed. Additional timer option is available in the B version for OTG supporting. A LDO, internally connected on IN pin, provided a protected output voltage even if an over voltage is present on IN pin.
