1.1 Introduction

The TPS1686-87EVM eFuse evaluation board allows for reference circuit evaluation of the Texas Instruments TPS1686 eFuse. The TPS1686 device is a 9V to 80V and 10A (RMS) eFuse with accurate and fast current monitoring capabilities. Features of the TPS1686 eFuse include:

  • Integrated FET
  • Ultra-low ON resistance: 16mΩ
  • Adjustable and robust over-current and short-circuit protections
  • Precise load current monitoring
  • Fast and adjustable undervoltage and overvoltage protections
  • Adjustable output slew rate control for inrush current protection
  • Built-in over-temperature protection to verity the FET safe operating area (SOA)
  • Adjustable over-current transient blanking timer that supports load transients
  • Integrated FET health monitoring and reporting
  • Analog die temperature monitor output
  • Dedicated fault and power-good indication pins

This EVM user’s guide describes the evaluation module (EVM) for the TPS1686 eFuse.
