High Side Power Switches
General Description
The MIC94060-63 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
over 2A of continuous current. The MIC94061and
MIC94063 features an active load discharge circuit
which insures capacitive loads retain no charge when
the main switch is in an OFF state.
MIC94060-61 feature rapid turn on while MIC94062-63
provide a slew rate controlled Soft-Start turn-on of 800µs
(typical) to prevent in-rush current from glitching supply
rails.
An active pull-down on the enable input keeps
MIC94060-63 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.
MIC94060-63’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.
