MIC94060/61/62/63 High Side Power Switches General Description Features The MIC94060-63 are high-side load switches designed 1.7V to 5.5V input voltage range for operation between 1.7V to 5.5V. The devices contain 2A continuous operating current a low on-resistance P-channel MOSFET that supports 77m (typ) R DSON over 2A of continuous current. The MIC94061 and Built-in level shift for control logic can be operated by MIC94063 features an active load discharge circuit 1.5V logic. which insures capacitive loads retain no charge when the main switch is in an OFF state. Low 2A quiescent current MIC94060-61 feature rapid turn on while MIC94062-63 Soft-Start: MIC94062-63 provide a slew rate controlled Soft-Start turn-on of 800s Micro-power shutdown <1A (typical) to prevent in-rush current from glitching supply Load discharge circuit: MIC94061, MIC94063 rails. Space saving 1.2mm x 1.6mm Thin MLF package An active pull-down on the enable input keeps MIC94060-63 in a default OFF state until the EN pin is pulled to a high level. Built-in level shift circuitry allows Applications low voltage logic signals to switch higher supply Load switch in portable applications: voltages, or vice versa high level logic signals can - Cellular phones control low level voltages. - PDAs MIC94060-63s operating voltage range makes them - MP3 players suitable for 1-cell Lithium ion and 2- to 3-cell NiMH/NiCad/Alkaline powered systems, as well as, all - Digital Cameras 5V applications. Their low operating current of 2A and - Portable instrumentation low shutdown current of <1A maximize battery life.
