2.3.3 Output Hot-Short Test

Use the following instructions to perform output Hot-Short test.

  1. Set the input supply voltage VIN to 12 V and current limit of 15 A. Turn ON the power supply.
  2. Short the output of the device for example, VOUT to GND with a shorter cable.
  3. Observe the waveforms using an oscilloscope.

Figure 3-4 shows test waveform of output hot-short on the TPS25983EVM eFuse Evaluation Board.
