Circuit Protection Misc Overvoltage Protection Controller

The NCP392D 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 NCP392D features an ACOK pin that indicates faulty condition.
