●General Description

Single channel high side switch IC for USB port is a

high side switch having over current protection used in

power supply line of universal serial bus (USB).

N-channel power MOSFET of low on resistance and

low supply current are realized in this IC.

And, over current detection circuit, thermal shutdown

circuit, under voltage lockout and soft start circuit are

built in.
