General Description

The MIC94066-69 are dual high-side load switches

designed for operation between 1.7V to 5.5V. The

devices contain a pair of low on-resistance,

115mΩ(max) P-channel MOSFETs that support over

2A of continuous current. The MIC94067 and

MIC94069 feature an active load discharge circuit

which insures capacitive loads retain no charge

when the main switch is in an OFF state.

An active pull-down on the enable input keeps

MIC94066-69 in a default OFF state until the EN pin

is pulled to a high level. The built-in level shift

circuitry allows for a logic signal that may be different

from the supply voltage to switch the high-side P-

channel MOSFET on or off.

MIC94066-67 feature rapid turn on while MIC94068-

69 provide a slew rate controlled Soft-Start turn-on

of 800µs (typical) to prevent in-rush current from

glitching supply rails.

MIC94066-69’s voltage range makes them suitable

for

NiMH/NiCad/Alkaline powered systems, as well as

all 5V applications. Their low operating current of

2µA and low shutdown current of <1µA maximize

battery life.
