LTC1470/LTC1471

Single and Dual

PCMCIA Protected

3.3V/5V V_CCSwitches

FEATURES

DESCRIPTIO

The LTC^®1470 switches the V_CCpins of a Personal Com-

puter Memory Card International Association (PCMCIA)

card slot between three operating states: OFF, 3.3V and

5V. Two low R_DS(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.

■

Single 3.3V/5V Switch in 8-Pin SO Package

■

Dual 3.3V/5V Switch in 16-Pin SO Package

■

Built-In Current Limit and Thermal Shutdown

■

Built-In Charge Pumps (No 12V Required)

■

Extremely Low R_DS(ON)MOSFET Switches

■

Output Current Capability: 1A

■

Inrush Current Limited (Drives 150µF Loads)

■

Quiescent Current in Standby: 1µA

The LTC1470 inputs are compatible with industry stan-

dardPCMCIAcontrollers.Abuilt-inXORensuresthatboth

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 sec-

tion). The switch rise times are controlled to eliminate

power supply glitching.

The LTC1470 features built-in SafeSlot^TMcurrent limit and

thermalshutdown.Theoutputislimitedto1Aduringshort

circuit to ground but 2A of peak operating current is

allowed.
