BD2202G, BD2206G
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.
Memory card slots of STB, Digital still camera, Cell Phones, Notebook PC.
