NCP374

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.
