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.
MIC94070-71 feature rapid turn on while MIC94072-73
provide a slew rate controlled Soft-Start turn-on of 800Вµs
(typical) to prevent in-rush current from glitching supply
rails.
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.
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 2ВµA and low
shutdown current of <1ВµA maximize battery life. …
