Power Management Switch IC Series for PCs and Digital Consumer Product

1ch Small Current Output

Power Management Switch ICs

BD2202G, BD2206G

No.09029EAT07

Description

The High-side switch for memory card slot is an IC High-side switch with a function of over-current protection used in the power

supply line of a memory card slot. In the switch part an N channel MOSFET low ON resistance has been 1 circuit integrated.

The switch goes OFF when the over-current condition lasts longer than the over-current shutdown time. The OFF switch is

set on latch off mode.The operating voltage range is 2.7V to 3.6V and the current limit value is set on 400mA, 1A.

Moreover, a soft start function, an under voltage lockout function and an over temperature protection function are integrated.

Feature

1) Single low on-resistance (Typ. = 150mΩ) Nch MOS FET

2) Continuous load current 0.2A(BD2202G) / 0.5A(BD2206G)

3) Control input logic: Active-High

4) Soft start function

5) Over current protection circuit

6) Over temperature protection circuit

7) Under voltage lockout

8) Power supply voltage range 2.7V～3.6V

9) Operating temperature range -25℃～85℃

Applications

Memory card slots of STB, Digital still camera, Cell Phones, Notebook PC.
