General Description
The MIC94040/1/2/3 is a family of high-side load switches designed to operate from 1.7V 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.
Key Features
- in a tiny 1.2mm x ® 1.2mm 4 pin MLF package. The MIC94040 and MIC94041 feature rapid turn on, while the MIC94042 and MIC94043 provide a slew rate controlled softstart turn-on of 100µs. The soft-start feature is provided to prevent an in-rush current event from pulling down the input supply voltage. The MIC94041 and MIC94043 feature an active load discharge circuit which switches in a 200Ω load when the switch is disabled to automatically discharge a capacitive load. An active pull-down on the en.
