Short-Circuit Protection Diagnosis Test

Use the following instructions to perform the short circuit protection diagnosis test

  1. Set the input supply voltage VIN to 48V and current limit of 10A.
  2. Enable the power supply.
  3. Now, toggle the SCP_TEST (TP9) and observe the response of G1PU/PD and FLTb pins during short circuit comparator (SCP) diagnosis.

Figure 3-8 shows the SCP_TEST response of TPS48100-Q1 device.
