2 Description

The TPS2597EVM eFuse Evaluation Board has three channels and enables evaluation of TPS25970A, TPS25972A, and TPS25974L eFuses from the TPS2597xx family. Channels 1, 2, 3 are standalone channels and provide programmable OVCSEL, OVLO, ITIMER, dVdt and ILM settings. The input power is applied at connectors J1, J9, J15 while J8, J14, J20 provides the output connection for Channels 1, 2, and 3 respectively. Refer to the schematic in Figure 3-1 and EVM test setup in Figure 5-1. TVS diodes D1, U7, and D14 provide input protection from transient overvoltages, while Schottky diode D2, D12, and D6 provide output protection for the TPS2597xx eFuses in Channels 1, 2, and 3 respectively.

S1, S2, and S3 allow U1, U2, and U3 to be RESET or disabled.
