DESCRIPTION

The MP62040/MP62041 Power Distribution

Switch is designed for high-side load switch.

The switch operates from 1.7V to 5.5V nominal

input voltage and includes an 85mΩ power

MOSFET to handle up to 2A continuous load.

The MP62040/MP62041 has slew rate control

when enabling the switch.

The built-in level shift function allows a logic

signal on enable input that may be different

from the supply voltage to switch the high side

P-channel MOSFET ON or OFF.

The MP62040/MP62041 is available in an ultra-

small UTQFN4 package, with ultra-low height

(0.55mm typ).

FEATURES

 2A Continuous Current

 85mΩ MOSFET

 Active High & Active Low Options

 Space saving 1.6x1.2 mm UTQFN4

Package (0.55mm Height)

APPLICATIONS

 Load switch in portable applications

 Battery switch-over circuits

 Level translator
