NCP373 - Over-Voltage and Over-Current protection device
Pin Pin Name Type 1,2 VBUS POWER 3 GND POWER 4 RES1 INPUT 5 RES2 INPUT 6 RES3 INPUT 7 Ilim OUTPUT Description VBUS voltage pins: must be hardwired together on the PCB.
These pins are connected to the VBUS connector, and are protected against positive and negative overvoltage events.

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 agains
