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.
