1.1 EVM Features

General TPS25981EVM eFuse evaluation board features include:

  • 2.7-V to 16-V (typical) operation
  • 1.5-A to 11-A programmable current limit using onboard jumpers
  • Programmable output voltage slew rate control
  • Programmable transient current blanking timer
  • Programmable current limit
  • TVS diode for input transient protection
  • Onboard Schottky diode at output prevents negative spike during overcurrent faults
  • LED status for Power Good and fault indication
