5.5 Input Reverse Polarity Test

Use the following instructions to perform Input Reverse Polarity test:

  1. Remove input TVS diode (D2).
  2. Set the input supply voltage VIN to 15 V and current limit of 5 A. Apply the supply in reverse polarity at J5 and enable the power supply.
  3. Observe VOUT and Input Current waveforms using an oscilloscope.

Figure 5-6 shows input reverse polarity response of LM73100 on LM73100EVM Ideal Diode Evaluation Board.
