Revision 1.0

General Description

The MIC95410 is a high-side load switch for computing

and ultra-dense embedded computing boards where high-

current low-voltage rails from sub-1V to 5.5V have to be

sectioned.

The

integrated

6.6m

Ω R

DS(ON)

N-channel

MOSFET ensures low voltage drop and low power

dissipation while delivering up to 7A of load current.

The MIC95410 is internally powered by a separated bias

voltage from 2.7V to 9V. It includes a TTL-logic level to

gate a voltage translator driving a charge pump, and an

output discharge function when disabled. The OFF-state

current from bias supply (VS) and the power switch OFF-

The

MIC95410

provides

user-adjustable

slew-rate-

controlled turn-on to limit the inrush current to the input

supply voltage.

The MIC95410 is available in a thermally efficient, space-

saving 10-pin 1.2mm x 2.0mm QFN package with 0.5mm

pin pitch and an operating junction temperature range from

–40°C to +125°C.
