5.4 Overcurrent Protection Test

Use the following instructions to perform the overcurrent test on the TPS1211Q1EVM:

  1. Enable the control input INP (TP6) of the main MOSFETS.
  2. By default, the EVM is configured for 5-A overcurrent protection.
  3. Now, load the output with rheostat or electronic load and gradually increase the load current to observe the overload behavior of TPS1211-Q1.
  4. Place jumper J3 at other settings to test at various overcurrent limits.

#T5536460-72 and #GUID-FF1E0BE8-BBC7-4752-A3FC-1B30E6A6D90E show test waveforms for an overcurrent fault.
