2ch High Side Switch ICs
0.5A Current Limit High Side Switch ICs
BD2046AFJ BD2056AFJ
General Description
BD2046AFJ and BD2056AFJ 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.
