3.1.5 Overload and Short Circuit Protection Test

Use the following instructions to perform over current test on the TPS1213Q1EVM

  1. Turn ON the power supply and set the power supply output VIN=12 V, current limit = 50 A.
  2. Set the Short Circuit Protection (SCP) threshold at 50 A by installing jumper J4 in 5-6 position and install jumper J3 in 1-2 position to set 1-ms delay.
  3. Uninstall J2 to enable the Active mode of operation.
  4. Now, load the output to 40 A with electronic load and apply a step of 15 A to observe the overload behavior of TPS12130-Q1.
  5. Disconnect the load.
  6. To perform short-circuit test, uninstall J3 to set shortest SCP delay.
  7. Now perform output short to capture the short-circuit behavior of TPS12130-Q1.
