Power Supply Selector Switch IC

for SD Cards

BD2204GUL

●Description

BD2204GUL is high side switch IC that has built-in 2

●Key Specifications

Input voltage range:

VIN1=2.7 to 4.5V

VIN2=1.2 to 2.4V

120mΩ(Typ.)

25μA(Typ.)

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.

ON resistance:

Operating current:

Standby current:

0.01μA(Typ.)

-40 to +85℃

Operating temperature range:
