MIC94090/1/2/3/4/5
High Side Load Switches for
Consumer Applications
General Description
Features
The MIC94090/1/2/3/4/5 is a family of high-side load switches
designed for operation from 1.7V to 5.5V input voltage. The
load switch pass element is an internal 130mΩ RDS(ON) P-
channel MOSFET which enables the device to support up to
1.2A continuous current. Additionally, the load switch
supports 1.5V logic level control and shutdown features.
• 1.7V to 5.5V input voltage range
• 1.2A continuous operating current
• 130mΩ RDS(ON)
• Internal level shift for CMOS/TTL control logic
• Ultra low quiescent current
The MIC94090 and MIC94091 feature rapid turn on. The
MIC94092 and MIC94093 provide a slew rate controlled soft-
start turn-on of 790µs, while the MIC94094 and MIC94095
provide a slew rate controlled soft-start turn-on of 120µs. The
soft-start feature option prevents an in-rush current event
from pulling down the input supply voltage.
The MIC94091, MIC94093, and MIC94095 include a 250Ω
auto discharge load circuit that is switched on when the load
switch is disabled.
An active pull-down on the enable input keeps the
MIC94090/1/2/3/4/5 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.
The MIC94090/1/2/3/4/5 operating voltage range makes
them ideal for Lithium ion and NiMH/NiCad/Alkaline battery
powered systems, as well as non-battery powered
applications. The devices provide low quiescent current and
low shutdown current to maximize battery life.
