MIC94090/1/2/3/4/5 High Side Load Switches for Consumer Applications General Description Features The MIC94090/1/2/3/4/5 is a family of high-side load switches 1.7V to 5.5V input voltage range designed for operation from 1.7V to 5.5V input voltage. The 1.2A continuous operating current load switch pass element is an internal 130m R P- DS(ON) 130m R DS(ON) channel MOSFET which enables the device to support up to Internal level shift for CMOS/TTL control logic 1.2A continuous current. Additionally, the load switch Ultra low quiescent current supports 1.5V logic level control and shutdown features. The MIC94090 and MIC94091 feature rapid turn on. The Micro-power shutdown current MIC94092 and MIC94093 provide a slew rate controlled soft- Rapid turn-on: MIC94090/1 start turn-on of 790s, while the MIC94094 and MIC94095 Soft-Start: MIC94092/3 (790s), MIC94094/5 (120s) provide a slew rate controlled soft-start turn-on of 120s. The Load discharge circuit: MIC94091/3/5 soft-start feature option prevents an in-rush current event Space saving and thermally capable 1.2mm x 1.2mm from pulling down the input supply voltage. Thin MLF package The MIC94091, MIC94093, and MIC94095 include a 250 Industry standard SC-70-6 package auto discharge load circuit that is switched on when the load switch is disabled. Applications An active pull-down on the enable input keeps the MIC94090/1/2/3/4/5 in a default OFF state until the enable pin Cellular phones is pulled above 1.25V. Internal level shift circuitry allows low Portable Navigation Devices (PND) voltage logic signals to switch higher supply voltages. The GPS modules enable voltage can be as high as 5.5V and is not limited by Personal Media Players (PMP) the input voltage. Ultra Mobile PCs The MIC94090/1/2/3/4/5 operating voltage range makes them ideal for Lithium ion and NiMH/NiCad/Alkaline battery Other Portable applications powered systems, as well as non-battery powered PDAs applications. The devices provide low quiescent current and Portable instrumentation low shutdown current to maximize battery life.
