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.
Additional voltage protection is available, from VBUS to IN. Due to
built−IN low RDS(on) NMOS fet, the host system is protected against
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.
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.
