2 Description

The TPS25961EVM eFuse Evaluation Board has one channel and enables evaluation of the TPS25961 eFuse. Channel 1 is standalone channel and provides programmable OVLO and ILM settings. The input power is applied at connector J1 while J5 provides the output connection. Refer to the schematic in Figure 3-1 and EVM test setup in Figure 5-1. TVS diode D1 provides input protection from transient overvoltages, while Schottky diode D3 provides output protection for the TPS25961 eFuse.

S1 allows U1 to be RESET or disabled.
