  • DRV8214: Registers Data Retention

    Resolved
    Part Number: DRV8214 Tool/software: Hi, One simple question related to Data Retention of the registers. If we enter in Low Power mode through the nSLEEP pin, the registers data vaules are retained or after returning to active mode it takes the default…

  • DRV8214: Ripple Counting Reliability with Carbon-brushed Motors

    Part Number: DRV8214 Hello E2E Experts, Our application uses an N20 gearmotor and would benefit from sensor-less motor position tracking. However, the motor requires carbon brushes to achieve adequate lifetime (due to frequent stop/start and reversing…

  • DRV8214: IPROPI pin to ADC

    TI Thinks Resolved
    Part Number: DRV8214 Tool/software: Hi team, if customer need to connect IPROPI to MCU ADC, is it necessary to use a buffer between IPROPI pin and MCU ADC? Thanks!\ Rayna

  • DRV8214: Using multiple DRV8214 on the same design

    Part Number: DRV8214 Dear all, I am wondering if there is anything stopping people from using multiple DRV8214 on the same microcontroller, except running out of i2c slave addresses. In that case, what would be the optimal way to monitor the position…

  • DRV8214: PWM work on 200kHz, Output waveform shape is not standard

    Part Number: DRV8214 Tool/software: Hi Team, Customer use 50kHz PWM and 200kHz PWM to run the DRV8214EVM. First capture is 200kHz, and second is 50kHz PWM. Customer questions are why the AOUT1 and AOUT2 looks like triangular waveform during decay. Could…

  • DRV8214: Device address

    Part Number: DRV8214 Tool/software: Hi, I’m having trouble establishing communication with the DRV8214 motor driver via I2C. I’ve configured the A0 and A1 pins to GND, which should result in a device address of 0x60 (according to the datasheet). However…

  • DRV8214: RC_OUT discrepancies with IPROPI pin

    TI Thinks Resolved
    Part Number: DRV8214 Tool/software: Dear Texas Instruments Support Team, I am writing to report an issue we are experiencing with the DRV8214EVM board. Attached, please find oscilloscope captures that illustrate the issue. During our analysis of the…

    TI Thinks Resolved
    Part Number: DRV8214 Tool/software: Hi Experts, I was wondering how to calculate the max speed that ripple counting can support. Could you pls guide it on it? thanks! Rayna

  • DRV8214: SCL internal pull-down

    Part Number: DRV8214 Tool/software: Motor driver team, On the DRV8214, the internal pull-down on SCL is leading to about 10uA of current draw for one customer's low power project. Is there a way to disable this pull down while idle, or avoid this current…
