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 4.5V to 20V. 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.
