Texas Instruments TPS25210EVM eFuse Evaluation Board

Texas Instruments TPS25210EVM eFuse Evaluation Board enables the evaluation of TPS25210A and TPS25210L eFuses from TPS25210 family. The TPS25210 is a 2.7V to 5.7V, 4A eFuse with integrated 31mΩ FET with reverse current protection. It also includes input reverse polarity protection, over-current, inrush current protection, adjustable over-current transient blanking timer, programmable under-voltage, and over-voltage protection. The input power is applied at connector J1, while J2 provides the output connection to the load. TVS diode, D3, provides input protection from transient overvoltages, while Schottky diode D2 provides output protection for the Texas Instruments TPS25210 eFuses. S1 allows U1 to be RESET or disabled. A power good (PG) indicator is provided by D5. Scaled device current can be monitored at TP8 with a scale factor of 0.13 V/A.
