Use the following instructions to perform the overcurrent test on the TPS25961 eFuse:
- Set the input supply voltage VIN to 12 V and current limit of 2 A and enable the power supply.
- Place jumper J3 in suitable position to set the required current limit as per Table 4-3.
- Apply an overload greater than the set current limit between VOUT and GND. (While testing current limit , use a resistive load to apply over current).
Figure 5-3 shows an example of the overcurrent test on the TPS25961EVM.
