TPS2595EVM: Evaluation Module for TPS2595xx
5.3 Wakeup at Output Short Test
Use the following instructions to perform wakeup at short test for CH3:
1. Set the input supply voltage (V
IN
) to 12 V at terminal T1 and turn OFF the power supply
2. By default, the EVM is configured for 2-A current limit
3. Short the output of CH3, that is, VOUT3 to GND with a shorter cable
4. Turn ON the power supply
Figure 5 shows test waveform of wakeup at output short for CH3 on the TPS2595EVM eFuse evaluation
board.

5.4 Overvoltage Clamp Test
Use the following instructions to perform the overvoltage test for CH3:
1. Set the input supply voltage (V
IN
) to 12 V at terminal T1 and enable the power supply
2. Set the load resistance to 500 Ω and connect at terminal T2 between VOUT3 and GND
3. Increase the input supply (V
IN
) from 12 V to 16 V and observe the waveforms using an oscilloscope
Figure 6 shows overvoltage response of the TPS259541 on the TPS2595EVM eFuse evaluation board.
