3.1.4 Input Reverse Polarity Test

Use the following instructions to test the input reverse polarity protection:

  1. Set the jumper setting on the EVM to the default position as shown in Table 3-1.
  2. Set the input supply voltage VIN to 60V and current limit of 10A.
  3. Connect the power supply positive to J6 and power supply negative to J5. The power supply is now connected in reverse polarity at the input of TPS48100-Q1.
  4. Enable the power supply.
  5. Observe the waveform at VOUT (TP2) with an oscilloscope.

Figure 3-9 shows input reverse polarity protection of TPS48100-Q1 on TPS4810Q1EVM Evaluation Board.
