MIC94042 - (MIC94040 - MIC94043) RDSON 3A High Side Load Switch

Download the MIC94042 datasheet PDF. This datasheet also covers the MIC94040 variant, as both devices belong to the same (mic94040 - mic94043) rdson 3a high side load switch family and are provided as variant models within a single manufacturer datasheet.

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.

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.

MIC94040/1/2/3 28mΩ RDSON 3A High Side Load Switch in 1.2mm x 1.2mm MLF® package 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. Additionally, the load switch supports 1.5V logic level control and shutdown 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.
