Ammeter Using all the jumpers, the EV kit circuit can be configured to evaluate the current-limit capability of the device. For Procedure example, with shunts on JU7 and JU8, the load is 249. The EV kit is fully assembled and tested. Follow the steps With shunt on JU2, the added resistance is 200. The below to verify board operation: on-resistance of the device is approximately 25. With 1) Verify that all jumpers are in their default positions, 25V input, the current going through the device can be as shown in Table 1. calculated as 25V/(249 + 25 + 200) = 52.7mA, but the actual current going through is limited by the device to 2) Install shunts on jumpers JU7 and JU8. be approximately 30mA. 3) Connect one side of the ammeter to 25V power supply and the other side to TP1 to measure the Table 1. Jumper Settings (JU1JU8) current going through the device and load. SHUNT 4) Connect the ground of the power supply to TP2. JUMPER DESCRIPTION POSITION 5) Install a shunt on jumper JU2. Installed TP1 connected directly to IN 6) Turn on the 25V power supply. Verify that the JU1 Not installed* TP1 not connected to IN ammeter reading is approximately 30mA. Installed TP1 connected to 200 to IN 7) Turn off the power supply. JU2 Not installed* TP1 not connected to IN 8) Remove the shunt on JU2. Install a shunt on jumper JU3. Installed TP1 connected to 500I IN JU3 9) Turn on the 25V power supply. Verify that the Not installed* TP1 not connected to IN ammeter reading is approximately 30mA. Installed TP1 connected to 1kI to IN JU4 10) Turn off the power supply. Not installed* TP1 not connected to IN 11) Remove the shunt on JU3. Install a shunt on Installed TP1 connected to 2k to IN jumper JU4. JU5 Not installed* TP1 not connected to IN 12) Turn on the 25V power supply.
