MIC94066-69
Dual High Side Power Switches General Description Features 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 Pchannel MOSFET on or off.
MIC94066-67 feature rapid turn on while MIC9406869 provide a slew rate controlled Soft-Start turn-on
of 800Вµs (typical) to prevent in-rush current from
glitching supply rails.
MIC94066-69’s 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. …
