5.4 Power Up into Short Test

Use the following instructions to perform wakeup into short test:

  1. Set the input supply voltage VIN to 5 V and current limit of 10 A. Keep the power supply OFF.
  2. Short the output of the device for example, VOUT to PGND with a very short cable.
  3. Turn ON the power supply.

Figure 5-6 shows test waveform of power up into output short on the TPS25210EVM eFuse Evaluation Board.
