MIC94080/1/2/3/4/5
67mΩ RDSON 2A High Side Load Switch
in 0.85mm x 0.85mm Thin MLFВ® Package General Description Features The MIC94080/1/2/3/4/5 is a family of high-side load switches
designed to operate from 1.7V to 5.5V input voltage. The load
switch pass element is an internal 67mΩ RDSON P-Channel
MOSFET which enables the device to support up to 2A of
continuous current. Additionally, the load switch supports 1.5V
logic level control and shutdown features in a tiny 0.85mm x
0.85mm 4-pin Thin MLFВ® package.
The MIC94080 and MIC94081 feature rapid turn on. The
MIC94082 and MIC94083 provide a slew rate controlled softstart turn-on of 800Вµs, while the MIC94084 and MIC94085
provide a slew rate controlled soft-start turn-on of 120Вµs. The
soft-start feature is provided to prevent an in-rush current
event from pulling down the input supply voltage.
The MIC94081, MIC94083, and MIC94085 feature an active
load discharge circuit which switches in a 250Ω load when the
switch is disabled to automatically discharge a capacitive load.
An active pull-down on the enable input keeps the
MIC94080/1/2/3/4/5 in a default OFF state until the enable pin
is pulled above 1.25V. Internal level shift circuitry allows low
voltage logic signals to switch higher supply voltages. The
enable voltage can be as high as 5.5V and is not limited by
the input voltage. …
