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 RDSON (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
