  • RE: DRV8847: Current Control

    Resolved
    Hi Dharmesh, This won't be possible while in independent half-bridge mode. Most of our industrial devices, while in independent half-bridge mode, require nSLEEP to be pulled low. We do have devices like the DRV8714-Q1 and DRV8718-Q1 that can do this…

  • DRV8847: Motor driver burned issue

    Part Number: DRV8847 Tool/software: Hi TI, We use DRV8847 to design a motor driver control board. However, it`s always burned under below work situation: Motor load: 20Ω. Vout=12V. Ipeak=150mA. Motor speed: 2-3Hz. Failure ratio: 100% Test number…

  • RE: DRV8847: How to replace KA3100D with DRV8847 ? i tried with 2 pin interface .but when i sent Inp1 & Inp2 both o or 1 , the respective outputs are improper.

    Dear David, In our hardware we are sending IN1,IN2,nSLEEP signals to DRV8847 serially using IC 74HC595 . Hence these signal bits either can be 0 or 1 . For moving thermal printer motor in forward direction , we are setting IN1 bit as 1, nSLEEP bit as 1…

  • DRV8847: how to reduce undershoot & overshoot at turn on & off

    Part Number: DRV8847 Tool/software: Hi expert, Would you please advise how to reduce undershoot & overshoot at turn on & off ? p.s. 1. motor supply is 5V 2. C18 has changed from MLCC 10uF/6.3V to 100uF/6.3V Regards, Allan

  • DRV8847: Motor drivers forum

    Part Number: DRV8847 Tool/software: Using DRV8847 to drive a dc motor，when power on,the nfault pin is high about 10 seconds then change to low level. The motor can run normarly. So I can't justify the motor condition. Please tell me how to check…
