Power Supply Selector Switch IC
for SD Cards
BD2204GUL
●Description
BD2204GUL is high side switch IC that has built-in 2
circuits of MOSFET. Switch has achieved 120m Ω
(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)
