2 Description

The TPS25980EVM eFuse Evaluation Board enables evaluation of TPS259804O eFuse from TPS25980x family. The input power is applied between connectors J1 and J3 while J2 and J5 provides the output connection to the load; refer to the schematic in Figure 1, and EVM test setup in Figure 2. D1/C1 provides input protection for the TPS259804O eFuse while D2/C2 provides output protection.

S1 allows U1 to be RESET or disabled. A power good (PG) indicator is provided by D3. Scaled device current can be monitored at TP15 with a scale factor of 0.13 V/A.
