DESCRIPTION

The MP62040-1/MP62041-1 Power Distribution

Switch is designed for high-side load switch

applications. 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 MP62040-1/MP62041-1 has slew rate

control with 115µs rise time to limit inrush

current when enabling the switch. In addition,

the part features a discharge function that

provides a resistive discharge path for the

external output capacitor when the part is

disabled.

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 MP62040-1/MP62041-1 is available in an

ultra-small UTQFN4 package, with ultra-low

height (0.55mm typ.).
