MIC94070/71/72/73

High Side Power Switches

General Description

Features

The MIC94070-73 are high-side load switches designed

for operation between 1.7V to 5.5V. The devices contain

a low on-resistance P-channel MOSFET that supports

1.2A of continuous current. The MIC94071 and

MIC94073 feature an active load discharge circuit which

insures capacitive loads retain no charge when the main

switch is in an OFF state.

• 1.7V to 5.5V input voltage range

• 1.2A continuous operating current

• 3A pulse current

• 120mΩ R_DSON(typical)

• Built-in level shift for control logic; can be operated by

1.5V logic.

• Low 2µA quiescent current

• Soft-Start: MIC94072/73

• Micro-power shutdown <1µA

MIC94070-71 feature rapid turn on while MIC94072-73

provide a slew rate controlled Soft-Start turn-on of 800µs

(typical) to prevent in-rush current from glitching supply

rails.

• Load discharge circuit: MIC94071, MIC94073

An active pull-down on the enable input keeps

MIC94070-73 in a default OFF state until the EN pin is

pulled to a high level. Built-in level shift circuitry allows

low voltage logic signals to switch higher supply

voltages, or vice versa; high level logic signals can

control low level voltages.

• Space saving 1.2mm × 1.6mm Thin MLF^®package

Applications

• Load switch in portable applications:

Cellular phones

PDAs

MP3 players

Digital Cameras

Portable instrumentation

MIC94070-73’s operating voltage range makes them

suitable for 1-cell Lithium ion and 2- to 3-cell

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.

Micrel’s web site at: www.micrel.com.

• Battery switch-over circuits

• Level translator
