Datasheet Load Switch ICs for Portable Equipment BD2202G-LB BD2206G-LB General Description Key Specifications This is the product guarantees long time support in Input voltage range: 2.7V to 3.6V Industrial market. The High-side switch, which has ON resistance : 150m(Typ.) over-current protection function, is used for the power Over current threshold: supply line of a memory card slot. In the switch part, an BD2202G 0.25A min., 1.0A max. N-channel MOSFET with low ON resistance has been 1 BD2206G 0.8A min., 1.6A max. circuit integrated. The switch goes OFF when the Standby current: 0.01 A (Typ.) over-current condition lasts longer than the Operating temperature range: -25 to +85 over-current shutdown time. The OFF switch is set to latch off mode. The operating voltage range is 2.7V to Package W(Typ.) D(Typ.) H (Max.) 3.6V and the current limit value is set on 400mA, 1A. SSOP5 2.90mm x 2.80mm x 1.25mm Moreover, functions of soft start, under voltage lockout, and over temperature protection are integrated.
