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) N-channel MOSFET built in.  3.3V and 1.8V are chosen and an output is possible.  0.5A Continuous Current load.  Reverse-current protection when power switch off.
