5.5 Output Hot-Short Test

Use the following instructions to perform output the hot-short test:

  1. Pre-charge the output voltage by following the steps in Pre-charging Functional Test.
  2. Now, enable the control input INP (TP6) of the main MOSFETS.
  3. Disable the pre-charge FET by connecting INP_G (TP24) to ground.
  4. Now, short the output, That is, VOUT to GND with a shorter cable and observe the short-circuit response of TPS48111-Q1 using an oscilloscope.

Figure 5-9 shows hot-short response of TPS48111-Q1 on TPS48111Q1EVM Evaluation Board.
