General Description
BD2062FJ and BD2066FJ are dual channel high side
switch ICs with an over-current protection for of
Universal Serial Bus (USB) power supply line. Its
switch unit has two channels of N-Channel power
MOSFET. Over current detection circuit, thermal
shutdown circuit, under-voltage lockout, and soft-start
circuit are built in.

Caution:
Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated
over the absolute maximum ratings.
