BD2202G-LB BD2206G-LB
General Description
Key Specifications
This is the product guarantees long time support in
Industrial market. The High-side switch, which has
over-current protection function, is used for the power
supply line of a memory card slot. In the switch part, an
N-channel MOSFET with 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 to
latch off mode. The operating voltage range is 2.7V to
3.6V and the current limit value is set on 400mA, 1A.
Moreover, functions of soft start, under voltage lockout,
and over temperature protection are integrated.
