NCP392C Adjustable Front End Overvoltage Protection Controller with Protected Vbus Output www.onsemi.com The NCP392C is an overvoltage front end protection controller and is able to disconnect the systems from its output pin in case wrong MARKING input operating conditions are detected, up to +28 V. Thanks to this DIAGRAM device using internal NMOS, no external device is necessary, reducing the system cost and the PCB area of the application board. 392Cx Internal OVLO threshold is available, or can be adjusted if an WLCSP 12 AYWW external resistor bridge is used. FCC SUFFIX CASE 567JM At power up (EN pin = low level), the Vout turns on tstart time after internal timer elapsed. 392Cx = Specific Device Number The NCP392C features an ACOK pin that indicates faulty 392Cx = (x = R or S) condition.
