Microchip MIC94063YMT-TR, 1High Side, High Side Power Switch IC 4-Pin, UDFN [MIC94063YMT-TR]; 598-194
The Microchip High side load switch is designed for operation between 1.7V to 5.5V. The device contains a low on-resistance P-channel MOSFET that supports over 2A of continuous current. It features an active load discharge circuit that ensures capacitive loads retain no charge when the main switch is in an OFF state. The device provides rapid turn-on, while the other version offers a slew-rate controlled soft-start turn-on of 800 μs (typical) to prevent in-rush current from glitching supply rails.
