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.
Prevent VIN1 and VIN2 from simultaneous-on.
Output Discharge Circuit

*3 When the switch changes from VIN1 to VIN2 or from VIN2 to VIN1, it is possible that VOUT voltage drops.
Dropped voltage of VOUT is specified as Voutdrop1 and Voutdrop2.
That voltage drop is caused by the function which prevents VIN1 and VIN2 from turning on simultaneously.
This function generates the period which both VIN1and VIN2 are turned off, and prevents the penetration
current between VIN1 and VIN2.

*TD1 and TD2 + TCOMP are period of Simultaneous-Off.
*TCOMP is period of VOUT becoming same voltage as VIN2.
*The value of Min. is in condition of IOUT=500mA and CL=15uF.
