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. …
Part Number: DRV8829 Hi team, I'd like to know about the resistance 1-Mohm between VM and VCP. Does it need this resistor? Why is the resistor listed? *EVM does not have this resistor. Sincerely. Kengo.
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.

Part Number: DRV8829 Hi team.
Our customer have created a schematic as your comment on E2E.
So could you check our schematic?

Is it possible to use internal…
Part Number: DRV8829 Hi team,
My customer would like to set I[4-0] as 100% fixed.
Can my customer connect V3P3OUT to I4-0 directly without inserting pull-up resistors?
I know I[4-0] is internally pulled down, but just want to make sure.
Regards,
It…
Part Number: DRV8829 Hi team.
I'd like to know about the Fault pin.
If the device shutdown in TSD, the nFault outputs LOW.
How is this signal reset?
Will it stay LOW if not reset?
Sincerely.
Kengo.
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.
Part Number: DRV8829 Other Parts Discussed in Thread: DRV8873 Hi team.
When 4A is output for 1 minutes, the surface temperature rises up to 100 C.
Could you give advice about heat dissipation ?
Sincerely.
Kengo.
