Datasheet
Power Supply Selector Switch IC
for SD Cards
BD2204GUL
General Description
BD2204GUL is high side switch IC that has built-in 2
circuits of MOSFET. Switch has achieved 120mΩ(Typ)
on-resistance. 3.3V power supply and 1.8V power
supply for memory card can be selected by SEL terminal.
Moreover, it has built-in simultaneous-on prevention
function at power switching, reverse-current protection
function to prevent reverse-current from output terminal
to input terminal at power-off, and discharge circuit to
discharge electricity in output terminal.
Features
 Dual channel of low on resistance (Typ = 120mΩ)
