2ch High Side Switch ICs for USB Devices and Memory Cards - BD2052AFJ

High side switch for USB is a high side switch having over current protection used in power supply line of universal serial bus (USB). Its switch unit has two channels of N-channel power MOSFET, and current of 500mA as USB standard can be flown to the respective channels. And, over current detection circuit, thermal shutdown circuit, under voltage lockout and soft start circuit are built in.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
