BD6516F, BD6517F, BD2042AFJ and BD2052AFJ
are dual channel high side switch ICs with an over
current protection for Universal Serial Bus (USB)
power supply line. The IC’s 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.
