●General Description
●Key Specifications
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.
