1.1 EVM Features

TPS25984EVM comes with two (2) TPS25984 eFuses connected in parallel to evaluate a 12-V (typical) and 110-A (steady-state) design. TPS25984EVM eFuse evaluation board features include:

  • 5-V to 16-V (typical) operation
  • 14-A to 120-A programmable circuit breaker threshold using onboard jumpers
  • Adjustable reference voltage for overcurrent protection and active current sharing blocks
  • Adjustable output voltage slew rate control
  • Adjustable transient current blanking timer
  • Adjustable current limit during start-up and active current sharing threshold using onboard jumpers
  • TVS diode for input and Schottky diode for output transient protections
  • LED status for power good and fault indications
  • Options to engage the power cycle and the quick output discharge (QOD)
  • Option to apply custom load transients using onboard MOSFETs, gate drive circuit, and load resistors
