  • DRV8711: DRV8711 RSTEP

    Part Number: DRV8711 Hi, I am developing motor control using DRV8711. Can you help me to understand the RSTEP function? We noticed BackEMF detection failures. but with RSTEP toggled on, we can get higher BackEMF voltage and pass the test. Another question…

  • DRV8711: DRV8711 OCP Issue

    Part Number: DRV8711 Other Parts Discussed in Thread: CSD18532NQ5B Hi, We use an DRV8711 in one of our devices, and have been seeing occasional instances of failure with an OCP error. In these cases, we tend to see the boards operate normally for 3-6…
