1.1 EVM Features

TPS25984BEVM comes with two (2) TPS25984B eFuses connected in parallel to evaluate a 12V (typical) and 110A (steady-state) design. TPS25984BEVM eFuse evaluation board features include:

  • 5V to 16V (typical) operation
  • 14A to 120A programmable circuit breaker threshold using onboard jumpers
  • Adjustable reference voltage for overcurrent protection and active current sharing blocks
  • Adjustable output voltage slew rate control
  • Fixed 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
