Hello Anthony,
Sorry for the delayed response.
I induced several vds faults as you suggested, and noticed that almost every time the faults occured on the high side mosfets. These faults were some times ocp and sometimes gate drive faults.
These…

Part Number: DRV8353 Other Parts Discussed in Thread: CSD18531Q5A , TIDA-010056 This component has been breaking anytime interact with it, really. I'm attaching the schematic and the SPI code, along with some screenshots of gate drive behavior. At this…
Hello Bob
If the DRV8350 mentions that registers are RW then they ought to be verifiable. Can you check by connecting a scope on the SSI pins, that the DRV8305 communication is happening correctly for the failing registers before we start debugging…
Part Number: DRV8350R hello Ti:
we learn the the TVS diodes can help with negative transient spikes.So we add a SMF15CA.You can my schematic diagram.
When I get my pcb.,I test it .The motor cann't run normally .Even one mosfet burned and one mosfet…
Part Number: DRV8350H-EVM Own DRV8350H hardware can not work
Hello, everyone.
I’ve built my own hardware for a three-phase-inverter with DRV8350H. The schematic is shown.
When I test this circuit, the DRV8350H didn't work.
The supply voltage VIN…
Part Number: DRV8350R hello , all :
we use DRV8350R to develop a BLDC Driver .The PCB have 3 DRV to drive 3 BLDC .
The motor we used have hall sensort , then depond on the hall sensor , we let DRV output different phase for BLDC to let it run .

Other Parts Discussed in Post: DRV8320 今回の記事では、統合型とディスクリート型の違いを箇条書きにして説明します。比較する設計は、本技術記事シリーズの Part 1 および Part 2 で取り上げた設計と同じものです。
絶えず基板面積の小型化が求められるという制約の下で、プリント基板（PCB）の設計者は、新たな可能性を求めて限界を超えようと努力を続けています。このような状況の中で、統合型マルチ・ハーフブリッジ・ドライバに注目が集まっています。PCBの小型化が進むのに対し…
Part Number: DRV8353
Hello, I would like to know if there is any problem on putting the shunt resistor between the SHx and the Phase, as shown below: SNA and SPA are the current amp inputs. Thus, there are some questions that are not clear to me: 1…
