2ch High Side Switch ICs
2.4A Current Limit High Side Switch ICs
BD2068FJ-M BD2069FJ-M
General Description
BD2068FJ-M and BD2069FJ-M 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.
