NCP392BRFCCT1G ON Semiconductor

NCP392B Adjustable Front End Overvoltage Protection Controller with Protected Vbus Output www.onsemi.com The NCP392B 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 MARKING using internal NMOS, no external device is necessary, reducing the DIAGRAM system cost and the PCB area of the application board. Internal OVLO threshold is available, or can be adjusted if external 392BR WLCSP 12 resistor bridge is used (A version). AYWW FCC SUFFIX At power up (EN pin = low level), the Vout turns on tstart time after CASE 567JM internal timer elapsed. Additional timer option is available in the B version for OTG A = Assembly Location Y = Year supporting. WW = Work Week A LDO, internally connected on IN pin, provided a protected output = PbFree Package voltage even if an over voltage is present on IN pin.
