1.3.6 One-Slot PC Card Power Interface Switch: ENE CP-2211
CP-2211 is single Slot PCMCIA and CardBus power switch. It integrates control logic, low switching resistance
MOSFET, over current alarm and over temperature auto shutdown circuits. It can deliver 3.3V or 5V to PC Card
VCCOUT and 3.3V, 5V or 12V to PC Card VPPOUT. The output current is up to 1A for VCCOUT and 250mA for
VPPOUT.
Low Switching Resistance (100mΩ for VCC Switch)
Over temperature auto shutdown
1A output current for VCCOUT
150mA output current for VPPOUT
Only 3.3V is required for chip normal operation
12V is not required for 3.3V or 5V Output
