NCP374

Overvoltage Up to +30 V

and Down to -30 V with

Load Switch Function

NCP374 is an over−voltage and over−current protection device.

From IN to VBUS , the part acts as a load switch protection, with

programmable current regulation. The current protection is externally

adjustable.

positive and negative voltage up to +28 V and down to −28 V.

The both embedded over−current and over−voltage protection

allows sustaining extreme conditions from short circuit on USB

connector, or defective WA or USB port.

TLLGA12

CASE 513AP

Due to the NCP374 using internal NMOS, the system cost and the

PCB area of the application board are minimized.

NCP374 provides a negative going flag (FLAG) output, which

alerts the system that a fault has occurred.
