MIC94044/5
28m ? R DSON 3A High Side Load Switch
in 1.2mm x 1.2mm MLF ? Package
General Description
Features
The MIC94044 and MIC94045 are high-side load switches
designed to operate from 1.7V to 5.5V input voltage. The
load switch pass element is an internal 28m ? R DSON
P-channel MOSFET which enables the device to support
up to 3A of continuous current. Additionally, the load
switch supports 1.5V logic level control and shutdown
features in a tiny 1.2mm x 1.2mm 4 pin MLF ? package.
The MIC94044/5 provides a slew rate controlled soft-start
turn-on of 1ms (typical) to prevent an in-rush current event
from pulling down the input supply voltage.
The MIC94045 features an active load discharge circuit
which switches in a 200 ? load when the switch is disabled
to automatically discharge a capacitive load.

28m ? R DSON
3A continuous operating current
1.2mm x 1.2mm space saving 4-pin MLF ? package
1.7V to 5.5V input voltage range
Internal level shift for CMOS/TTL control logic
Ultra low quiescent current
Micro-power shutdown current
Soft-Start: 1ms
Load discharge circuit: MIC94045
Ultra fast turn off time
Junction operating temperature from -40oC to +125oC
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 MIC94044/5 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.
