Overview
MIC94040/1/2/3 28mΩ RDSON 3A High Side Load Switch in 1.
2mm x 1.
2mm MLF® package General Description The MIC94040/1/2/3 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 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 features in a tiny 1.
2mm x ® 1.
2mm 4 pin MLF package.
The MIC94040 and MIC94041 feature rapid turn on, while the MIC94042 and MIC94043 provide a slew rate controlled softstart turn-on of 100µs.
The soft-start feature is provided to prevent an in-rush current event from pulling down the input supply voltage.
The MIC94041 and MIC94043 feature an active load discharge circuit which switches in a 200Ω load when the switch is disabled to automatically discharge a capacitive load.
An active pull-down on the enable input keeps the MIC94040/1/2/3 in a default OFF state un...
