TPS25980EVM: Evaluation Module for TPS25980x efuse
1
Introduction
The
TPS25980EVM eFuse Evaluation Board
allows reference circuit evaluation of Texas Instruments (TI)
TPS25980x eFuse. The TPS25980x device is 2.7 V to 24 V, 8 A eFuse with integrated 2.7 mOhm FET,
programmable under voltage, over current, inrush current protection and configurable number of Auto-
retries and Retry Delay features.

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
, and EVM test setup in
. 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.
