Part Number: DRV8711 Tool/software: I want to know the SPI Mode supported by the DRV8711 part.
If you look at the DRV8711 part Datasheet, you will see the SPI Data Format as shown below.
Looking at the picture, it seems to support SPI Mode 0 and SPI…
Part Number: DRV8711 Tool/software: Hi Team,
Here we are using DRV8711 driver for Brushed DC motor with N-channel mosfets. According to calculation from provided formula in DRV8711 datasheet for full scale current must be 3A but current is limited below…
Hi Dhivya,
For normal operation APDF and BPDF must not be set. These are pre-driver fault indicator bits. If they're set the outputs will be disabled. Your system should have normal operation when these bits are not set. Thanks.
Regards, Murugave…
Hi Dhivya,
It's difficult to tell from the scope captures provide which signal is which. Can you please add labels to these images? If following in order from Murugavels suggested nodes of capture, it looks like x2HS is the only gate that is seeing any…
Hi Arun,
I can not see anything wrong with output voltages, T_off is around 30us what is good and according to settings. I guess you use DRV8711 in indexer mode ie.
PWMMODE is set to 0. In this mode DRV8711 sets automatically PWM duty cycle to get desired…
Part Number: DRV8711 Other Parts Discussed in Thread: DRV8452 , DRV8434 , DRV8462 Tool/software: Dear TI Support Team,
I would like to inquire if the DRV8711 can be operated using only PWM and GPIO signals, without requiring SPI communication. Our application…
Part Number: BOOST-DRV8711 Other Parts Discussed in Thread: DRV8711 , Tool/software: Hi Team,
We are working with the DRV8711 stepper driver and the PR57HS112-4204-01-R stepper motor.
Referring to the driver chip datasheet, we have configured the motor…
Part Number: DRV8711 Tool/software: Hello Sir/Madam,
I am using the DRV8711 for both stepper and BDC motors in my drivers, but I am encountering a stalling issue. I am using the AUIRF540ZSTRL MOSFET to drive the motor, which can handle up to 3A. However…
Part Number: DRV8711 Tool/software: Hello sir,
I am using 0.01 E current sense resistor for stepper motor. But, for DC motor it is not suitable please help to choose the current sense resistor.
Part Number: DRV8711 Tool/software: Hello team,
We are working DRV8711 stepper motor driver with STM32F429IGT6 controller for our application. When we work with the driver, it automatically stopped after running few minutes. We are configured all registers…
