General Description

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 28mΩ RDSON 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

Key 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 200Ω load when the switch is disabled to automatically discharge a capacitive load. Internal level shift circuitry allows low voltage logic signals to switch higher supply voltages. The enable voltage can be as high as.
