Micrel MIC94067
The MIC94067 and MIC94069 feature an active load discharge circuit which insures capacitive loads retain no charge when the main switch is in an OFF state. The built-in level shift circuitry allows for a logic signal that may be different from the supply voltage to switch the high-side Pchannel MOSFET on or off.| Part No. | MIC94067 |

GENERAL DESCRIPTION
The MIC94066-69 are dual high-side load switches designed for operation between 1.7V to 5.5V. The devices contain a pair of low on-resistance, 115mΩ(max) P-channel MOSFETs that support over 2A of continuous current. An active pull-down on the enable input keeps MIC94066-69 in a default OFF state until the EN pin is pulled to a high level. MIC94066-67 feature rapid turn on while MIC9406869 provide a slew rate controlled Soft-Start turn-on of 800µs (typical) to prevent in-rush current from glitching supply rails. MIC94066-69’s 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 atFEATURES
