Description

The MIC94062YC6TR is a high-side load switch designed for operation between 1.7V to 5.5V. It contains a low on-resistance P-channel MOSFET that supports over 2A of continuous current. The MIC94062YC6TR features a slew rate controlled Soft-Start turn-on of 800µs (typical) to prevent in-rush current from glitching supply rails. It also has an active pull-down on the enable input to keep it in a default OFF state until the EN pin is pulled to a high level. The MIC94062YC6TR is suitable for 1-cell Lithium ion and 2- to 3-cell NiMH/NiCad/Alkaline powered systems, as well as, all 5V applications. Its low operating current of 2µA and low shutdown current of <1µA maximize battery life.
