Texas Instruments TPS2597EVM eFuse Evaluation Module (EVM)

Texas Instruments TPS2597EVM eFuse Evaluation Module (EVM) allows the reference circuit evaluation of the TPS2597xx eFuse family of products. The TPS2597xx devices are a 2.7V to 23V, 7A eFuses with integrated 10mΩ FET with over current, inrush current protection, adjustable over-current transient blanking timer, programmable under-voltage, and over-voltage protection. The Texas Instruments TPS2597EVM eFuse Evaluation Module 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, and J15 while J8, J14, and J20 provide the output connection for Channels 1, 2, and 3.
