1.1 Introduction

The TPS1685EVM eFuse Evaluation Board allows reference circuit evaluation of Texas Instruments' TPS1685 eFuse. The TPS1685 device is a 9V to 80V and 20A (RMS) stackable eFuse with an accurate and fast current monitoring capability. This device supports the parallel connection of multiple eFuses for higher current designs by actively synchronizing the device states and sharing the loads during start-up and steady state. The TPS1685 eFuse has an integrated FET with ultra-low ON resistance of 4.3mΩ, adjustable and robust over-current and short-circuit protections, precise load current monitoring, fast adjustable undervoltage and overvoltage protections, adjustable output slew rate control for inrush current protection, and built-in over-temperature protection to verify FET safe operating area (SOA). TPS1685 eFuse also has an adjustable over-current transient blanking timer to support load transients, integrated FET health monitoring, and reporting, analog die temperature monitor output, dedicated fault and power good indication pins.

This user’s guide describes the evaluation module (EVM) for the TPS1685 eFuse.
