Power Management Switch ICs for PCs and Digital Consumer Products Load Switch ICs for Potable Equipment BD2202G, BD2206G ● 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. ● Line up Parameter BD2202G BD2206G Continuous load current (A) 0.2 0.5 Short circuit current limit (A) 0.4 1.0 Logic Control input High High ● Absolute Maximum Ratings Parameter Symbol Limits Unit Supply voltage VIN -0.3 to 6.0 V En voltage VEN -0.3 to 6.0 V OUT voltage VOUT -0.3 to VIN + 0.3 V Storage temperature TSTG -55 to 150 °C Power dissipation PD 675 *1 mW *1 Mounted on 70mm * 70mm * 1.6mm grass-epoxy PCB. Derating : 5.4mW/℃ for operating above Ta=25℃ * Does not do radiation resistance design. * There is no operation guarantee. ● Operating conditions ◎ BD2202G Parameter Symbol Limits Unit Operating voltage range VIN 2.7 to 3.6 V Operating temperature range TOPR -25 to 85 °C Operating load current ILO 0 to 200 mA ◎ BD2206G Parameter Symbol Limits Unit Operating voltage range VIN 2.7 to 3.6 V Operating temperature range TOPR -25 to 85 °C Operating load current ILO 0 to 500 mA No.11029EBT07 |
