General Description

The MIC94090/1/2/3/4/5 is a family of high-side load switches

designed for operation from 1.7V to 5.5V input voltage. The

load switch pass element is an internal 130mΩ R

channel MOSFET which enables the device to support up to

1.2A continuous current. Additionally, the load switch

supports 1.5V logic level control and shutdown features.

The MIC94090 and MIC94091 feature rapid turn on. The

MIC94092 and MIC94093 provide a slew rate controlled soft-

start turn-on of 790µs, while the MIC94094 and MIC94095

provide a slew rate controlled soft-start turn-on of 120µs. The

soft-start feature option prevents an in-rush current event

from pulling down the input supply voltage.

The MIC94091, MIC94093, and MIC94095 include a 250Ω

auto discharge load circuit that is switched on when the load

switch is disabled.

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

is pulled above 1.25V. 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 MIC94090/1/2/3/4/5 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.
