TPS25947EVM

TPS25947EVM eFuse Evaluation Module (EVM)

Texas Instruments TPS25947EVM eFuse Evaluation Module (EVM) has 4 channels and enables evaluation of TPS259470L, TPS259472A and TPS259474L eFuses from the TPS25947xx family. Channels 1 and 4 are standalone channels and provide programmable OVCSEL, OVLO, ITIMER, dVdt, and ILM settings. Channels 2 and 3 share a common ground plane and provide the option to evaluate power muxing and parallel operation capabilities of TPS25947xx eFuse. The input power is applied at connectors J1, J9, J12, J16 while J2, J8, J11, J15 provide the output connection for Channels 1, 2, 3, and 4 respectively. TVS diodes D1, U7, D14, and D5, provide input protection from transient overvoltages, while Schottky diodes D2, D12, D15, and D6 provide output protection for the Texas Instruments TPS25947xx eFuses in Channels 1, 2, 3, and 4, respectively. S1, S2, S3, and S4 allow U1, U2, U3, and U4 to be RESET or disabled. A Power Good (PG) indicator is provided by D3. A scaled device current can be monitored at TP15, with a scale factor of 0.13 V/A.
