GENERAL DESCRIPTION

The SGM2531 and SGM2531A are single-channel load

switches with controlled slew rate. The VOUT rise time

can be programmed by setting an additional capacitor

to the SS pin, which can minimize inrush current. The

devices contain an N-MOSFET that can operate over

an input voltage range of 4V to 22V. With precision 5%

current limit, the devices can provide excellent

accuracy and be well applied to many system

protection applications.

Programmable under-voltage lockout or over-voltage

protection is used to turn off the device if the VIN drops

below or raises over a threshold value, 3% threshold

accuracy ensures tight that the downstream circuitry is

not damaged by unintended power supply. Fault

conditions are indicated by the nFLT pin.

The SGM2531 and SGM2531A are available in Green

SOIC-8 (Exposed Pad) and TDFN-2×3-8BL packages.
