for Potable Equipment
No.11029EBT07
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.
