Micrel MIC94064
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.| Part No. | MIC94064 |

GENERAL DESCRIPTION
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. 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 and 2- to 3-cell NiMH/NiCad/Alkaline powered systems, as well as all 5V applications. Their low operating current of 2µA and low shutdown current of <1µA maximize battery life. Data sheets and support documentation can be found on Micrel’s web site at:FEATURES
