  • 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…

  • DRV8213EVM: DRV8214 vs DRV8213EVM

    Part Number: DRV8213EVM Other Parts Discussed in Thread: DRV8213 , DRV8214EVM , , DRV8214 Tool/software: Hi team, Could you use the DRV8214EVM to evaluate the DRV8213 properly too? Thank you. Kind regards, Wouter Kragt

  • DRV8214: I made an open-source Arduino/ESP32/STM32 I2C library for sensorless DC motor driver available on Github

    TI Thinks Resolved
    Part Number: DRV8214 Tool/software: Hello, I saw someone asking on the TI forum whether an Arduino Library existed for the DRV8214 driver, and since I also needed one and couldn't find anything online, I created one myself. It is still a work in progress…

  • 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…

  • DRV8214: Recommendations for Accurate Ripple Counting at Lower PWM Duty Cycles

    Resolved
    Part Number: DRV8214 Tool/software: Hello, I've been using the DRV8214 to drive a small brushed DC motor. It performs well when operating at a 100% duty cycle, but the ripple counts become quite noisy when I reduce the PWM duty cycle to 50%. I understand…

  • RE: DRV8214: SCL internal pull-down

    Hi Darren, Understood. To reduce overall current consumption while the device is in the sleep state would be to reduce the motor voltage (if possible) and make inputs = 0V. I'm not sure how much of an affect this will have on the SCL leakage current but…

  • RE: DRV8214: Need Body Diode Characteristics

    Hi Divya, Divya Jyoti Pandey said: I require formal documentation or an updated datasheet from TI specifying the following: Reverse Recovery Time (trr) Reverse Leakage Current Peak Current Capability Maximum Continuous Current Handling Capability (reiterating…

  • DRV8214: DRV8214 Speed & Voltage Regulation

    Part Number: DRV8214 Tool/software: Hi all, Now my customer use DRV8214 for HVAC application for valve control. The customer encountered several issues while use it: 1. The customer set target voltage. But when actually controlled, the voltage is variable…
