5.5 Overvoltage Clamp Test

Use the following instructions to perform the overvoltage protection test on channel 1:

  1. Remove input TVS diodes.
  2. Set the input supply voltage VIN to 12 V and current limit of 10 A. Apply the supply between VIN1 and PGND1 at connector J1 and enable the power supply.
  3. Increase the input supply VIN from 12 V to 16 V and observe the waveforms using an oscilloscope.

Figure 5-6 shows overvoltage response of TPS25972x on the TPS2597EVM eFuse evaluation board.
