Texas Instruments TPS25985EVM eFuse Evaluation Module

Texas Instruments TPS25985EVM eFuse Evaluation Module (EVM) allows reference circuit evaluation of the TPS25985 eFuse. The TPS25985 device is a 4.5V to 16V, 80A eFuse with integrated 0.59mΩ FET. It comes with overcurrent, inrush current protection, adjustable overcurrent transient blanking timer, programmable undervoltage, and overvoltage protection. The Texas Instruments TPS25985EVM comes with two (2) TPS25985 eFuses connected in parallel to evaluate a 12V (typical) and 120A (steady state) design.

Features

  • 5V to 16V operation (Typ.)
  • 28A to 100A programmable circuit breaker threshold using onboard jumpers
  • Adjustable reference voltage for overcurrent protection and active current-sharing blocks
  • Programmable transient current blanking timer
  • Programmable output slew rate control, UVLO, current limit during startup, and active current sharing threshold
  • LED status for power good and fault indications

Required Equipment

  • Power supplies
    • One adjustable power supply with 0V to 30V output and 0A to 200A output current limit
  • Oscilloscope
    • A DPO2024 or equivalent, three 10x voltage probes, and a DC current probe of 150A rated
  • Meters
    • Two (2) Digital Multi Meters (DMM)
  • Loads
    • One resistive load or equivalent which can tolerate up to 200A DC load at 24V
