MIC94064 - High Side Power Switches

Datasheet Summary

Description

The MIC94064 and MIC94065 are high-side load switches designed for operation between 1.7V to 5.5V.

The devices contain a low on-resistance P-channel MOSFET that supports over 2A of continuous current.

Features

  • an active load discharge circuit which insures capacitive loads retain no charge when the main switch is in an OFF state. An active pull-down on the enable input keeps MIC94064/5 in a default OFF state until the EN pin is pulled to a high level. Built-in level shift circuitry allows low voltage logic signals to switch higher supply voltages, or vice versa; high level logic signals can control low level voltages. The MIC94064/5’s operating voltage range makes them suitable for 1-cell Lithium ion.

MIC94064/5 High Side Power Switches General Description The MIC94064 and MIC94065 are high-side load switches designed for operation between 1.7V to 5.5V. The devices contain a low on-resistance P-channel MOSFET that supports over 2A of continuous current. The MIC94064/5 provides a slew rate controlled SoftStart turn-on of 115µs (typical) to prevent in-rush current from glitching supply rails. The MIC94065 features an active load discharge circuit which insures capacitive loads retain no charge when the main switch is in an OFF state. An active pull-down on the enable input keeps MIC94064/5 in a default OFF state until the EN pin is pulled to a high level.
