5.3 Output Hot-Short Test

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

  1. Set the input supply voltage VIN to 5 V and current limit of as high as possible. Turn ON the power supply.
  2. Short the output of the device for example, VOUT to PGND with a very short cable.
  3. Observe the waveforms using an oscilloscope.

Figure 5-5 shows the test waveform of output hot-short on TPS25210EVM eFuse Evaluation Board.
