Use the following instructions to evaluate the thermal performance of TPS25984BEVM:

1. Configure the Jumper J6 position to desired reference voltage (V_IREF) for overcurrent protection and active current sharing as mentioned in Table 4-3. The "1-2" position of the jumper J6 is selected in this experiment, which makes V_IREF as 1V (typical).
2. Configure the jumpers J5 and J7 in a good position to set required steady state current limit threshold (I_OCP) as per Table 4-3. The "1-2" position of the jumpers J5 and J7 are selected in this experiment, which makes I_OCP as 120A (typical) with V_IREF as 1V (typical).
3. Set the input supply voltage VIN to 12V and current limit of 115A.
4. Connect the power supply between VIN (Connector T1) and PGND (Connector T3) and enable the power supply.
5. Now apply a load of 110A (DC) between VOUT (Connector T2) and PGND (Connector T3) for half an hour or more to reach the thermal equilibrium point.
6. Capture the thermal image of the EVM or monitor the voltage at TEMP (TP12) pin using a digital multimeter. Voltage at the TEMP (V_TEMP) pin reports the maximum die temperature between two (2) TPS25984B eFuses, which can be obtained using Equation 1.
   Equation 1. $T_J\left(°C\right)=\left[25+\left\{\frac{V_{TEMP}\left(mV\right)-677.6}{2.72 \left(mV/°C\right)}\right\}\right]$

Figure 5-16 shows the thermal performance of TPS25984BEVM with two (2) TPS25984B eFuses in parallel.
