MIC94064/5 High Side Power Switches General Description Features The MIC94064 and MIC94065 are high-side load 1.7V to 5.5V input voltage range switches designed for operation between 1.7V to 5.5V. 2A continuous operating current The devices contain a low on-resistance P-channel 77m (typ) R DSON MOSFET that supports over 2A of continuous current. Built-in level shift for control logic can be operated by The MIC94064/5 provides a slew rate controlled Soft- 1.5V logic. Start turn-on of 115s (typical) to prevent in-rush current Low 2A quiescent current from glitching supply rails. Soft-Start: 115s The MIC94065 features an active load discharge circuit Micro-power shutdown <1A which insures capacitive loads retain no charge when the main switch is in an OFF state. Load discharge circuit: MIC94065 An active pull-down on the enable input keeps Space saving 1.2x1.6 mm Thin MLF package MIC94064/5 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 voltages, or vice versa high level logic signals can Load switch in portable applications: control low level voltages. - Cellular phones The MIC94064/5s operating voltage range makes them - PDAs suitable for 1-cell Lithium ion and 2- to 3-cell - MP3 players NiMH/NiCad/Alkaline powered systems, as well as all 5V - Digital Cameras applications. Their low operating current of 2A and low - Portable instrumentation shutdown current of <1A maximize battery life.
