NCP392A
Adjustable Front End
Overvoltage Protection
Controller with Protected
Vbus Output
The 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.
