功能描述

The LTC1470 switches the VCC pins of a Personal Computer Memory Card International Association (PCMCIA) card slot between three operating states: OFF, 3.3V and 5V. Two low RDS(ON) N-channel power MOSFETs are driven by a built-in charge pump which generates a voltage higher than the supply voltage to fully enhance each switch when selected by the input control logic.

The LTC1470 inputs are compatible with industry standard PCMCIA controllers. A built-in XOR ensures that both switches are never on at the same time. This function also makes the LTC1470 compatible with both active-low and active-high controllers (see Applications Information section). The switch rise times are controlled to eliminate power supply glitching.

The LTC1470 features built-in SafeSlot? current limit and thermal shutdown. The output is limited to 1A during short circuit to ground but 2A of peak operating current is allowed.

The LTC1471 is a dual version of the LTC1470 and is available in a 16-pin SO package.
