NCP373

NCP373 Overvoltage Up to +30 V and Down to -30 V with Load Switch Function NCP373 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, up to 400 mA or 1300 mA, depending on selected version. 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 voltages up to ±28 V. The embedded over−current and over−voltage protection allow the device to sustain extreme conditions from short circuit on USB connector, or defective WA or USB port. Because to the NCP373 using internal NMOS, the system cost and the PCB area of the application board are minimized. NCP373 provides a negative going flag (FLAG) output, which alerts the system that a fault has occurred.
