  Part Number: DRV8829 Tool/software: Hi team, I had a lot of VIAs in the thermal pad area, but solder flowed into that area, weakening the solder joint and causing heat problems. I'm thinking of filling the VIAs with resist to prevent this problem, but…

  Part Number: DRV8829 Hi team, Doesn't it mean that the high-side FET cannot be turned off not only during power-off / sleep but also during normal operation? This post says that this resistor is only valid in power off and sleep modes. Sincerely…

• DRV8829: OUTx shorted to GND.

  TI Thinks Resolved

  Part Number: DRV8829 Hi team, The resistance value of the OUTpin to GND was 0.1Ω. I think the Lowside FET seems to be broken. What are the factors that cause the Lowside FET to break? What is the current rating of the Lowside FET? Sincerely. Kengo.

• RE: DRV8829: DRV8829 with linear actuator

  Marion， If adding a Rsense and 25uH series inductor doesn’t work, I don’t think the 8.2uH can work. In this case, we have to measure the DRV8829’s output current and switching node voltage to understand the issue.
