2 Description

The TPS25210EVM eFuse Evaluation Board enables the evaluation of TPS25210A and TPS25210L eFuses from TPS25210 family. The input power is applied at connector J1, while J2 provides the output connection to the load; refer to the schematic in Figure 3-1 and EVM test setup in Figure 5-1. TVS diodes D3 provides input protection from transient overvoltages while Schottky diode D2 provides output protection for the 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.
