Product Overview
The MIC94040YFL-TR is a high-side Load Switch designed to operate from 1.7 to 5.5V input voltage. The load switch pass element is an internal 28mΩ RDSON P-channel MOSFET which enables the device to support up to 3A of continuous current. The soft-start feature is provided to prevent an in-rush current event from pulling down the input supply voltage. An active pull-down on the enable input keeps the MIC94040 in a default OFF state until the enable pin is pulled above 1.2V. Internal level shift circuitry allows low voltage logic signals to switch higher supply voltages. The enable voltage can be as high as 5.5V and is not limited by the input voltage. The MIC94040 operating voltage range makes them ideal for Lithium ion and NiMH/NiCad/Alkaline battery powered systems, as well as non-battery powered applications. The devices provide low quiescent current and low shutdown current to maximize battery life.
- Internal level shift for CMOS/TTL control logic
- Ultralow quiescent current
- Micro-power shutdown current
- Ultra fast turn off time
