Power Supply Selector Switch IC for SD Cards - BD2204GUL

BD2204GUL is high side switch IC that has built-in 2circuits of MOSFET. Switch has achieved 120mO(Typ.) on-resistance. 3.3V power supply and 1.8Vpower supply for memory card can be selected by SELterminal. Moreover, it has built-in simultaneous-onprevention function at power switching, reverse-currentprotection function to prevent reverse-current fromoutput terminal to input terminal at power-off, anddischarge circuit to discharge electricity in outputterminal.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
