Part Number: DRV8711 Hi fiends,
While testing my DRV8711 first design, I discover that the part is heating a lot. I suspect that the internal voltage regulator 5V is heating.
My measuremets: at 48V, the chip no load current (motor OFF but no sleep…
Part Number: DRV8711 Dear TI Team,
We are using a single DRV8711 IC to control two BDC motors.
For Motor 1 , connected to AIN1/AIN2 with the motor connected to Motor Output 4,5 , we are able to vary the motor speed, but the motor rotates only in the…

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…
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…
Part Number: DRV8711 Other Parts Discussed in Thread: TIDA-01227 , CSD19538Q3A , , LM5107 Tool/software: Dear TI Technical Support Team,
I am currently working on a 4-channel stepper motor driver design using the DRV8711 IC, where we have selected SQJ952EP…
Part Number: DRV8711 Tool/software: Hello, experts
The parameters of the motor we use are shown in the figure. When the step pulse frequency is 11kHz, the current waveform is abnormal.
I read the document SLVA637, but still couldn't find better parameters…
Part Number: DRV8711 Dear TI E2E Community,
I am using the DRV8711 to drive a 1.8° two-phase stepper motor in 1/256 microstepping mode. I have successfully achieved basic motor rotation. My goal is to implement zero-jerk startup using an external absolute…
Part Number: DRV8711 My customer use DRV8711 for motor driver in printer application,The stepper motor can be controlled by DRV8711 normally, but the customer found that the current waveforms of phase A (yellow) and phase B(green) are asymmetric. The…
