MIC94041 - 3A High-Side Load Switch

Download the MIC94041 datasheet PDF. This datasheet also covers the MIC94040 variant, as both devices belong to the same 3a high-side load switch family and are provided as variant models within a single manufacturer datasheet.

General Description

The MIC94040, MIC94041, MIC94042, and MIC94043 are 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 28 mΩ RDS(ON) P-channel MOSFET which enables the device to support up to 3A of continuous current.

Key Features

  • 28 mΩ RDS(ON).
