Hi Brianwu,

1. Share an AN of transient thermal measurements for your reference in the attachment. You can refer to the following formula to calculate.

2. For failure analysis, I can offer you some suggestions as below.

2.1 Check if the wiring between devices is connected properly in the test platform.

2.2 Check the schematic for errors.

2.3 Check the driver IC signal is output properly.

2.4 Analysis the failure waveforms if you captured it when the failure happened.

Hope the above suggestions will be helpful to you.

Best regards,

Rachel
