1.1 EVM Features

General TPS22811EVM load switch evaluation board features include:

  • 2.7-V to 16-V (typical) operation
  • Programmable output voltage slew rate control

  • Load current monitor output (IMON)

  • TVS diode for input transient protection
  • Onboard Schottky diode at output prevents negative spike during overcurrent faults
  • LED status for power indication
