Abstract

This user’s guide describes the evaluation module (EVM) for the TPS25984 eFuse. The TPS25984 device is a 4.5-V to 16-V and 70-A (peak) stackable eFuse with accurate and fast current monitor. This device supports 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 TPS25984 eFuse has an integrated FET with ultra-low ON resistance of 0.8 mΩ, adjustable and robust overcurrent and short-circuit protections, precise load current monitoring, fast overvoltage protection (fixed 16.7-V threshold), adjustable output slew rate control for inrush-current protection, and overtemperature protection to verify FET SOA. The TPS25984 eFuse also has adjustable overcurrent transient blanking timer to support load transients, adjustable undervoltage protection, integrated FET health monitoring and reporting, analog die temperature monitor output, and dedicated fault and power good indication pins.
