Part Number: DRV8243-Q1

Tool/software:

Hi, 

can we disable the DRV8243 using SPI ??, in PWM mode??. i have seen in datasheet it mentioned for Independent EN/PH mode not clearly mentioned for PWM mode whether it applicable or not??.  Please clarify on that.

Also, IN1 and IN2 control using SPI in PWM mode also possible or not??.

Thanks,

    Hi,

    Thank you for your questions. DRVOFF is function to disable output. Then here is table and top one is allow to make disable output via SPI register only.

    regards

    Thanks for you reply...

    we are planning this feature in PWM mode, will it work for PWM mode?, or it limited to few modes only??, in datasheet it is mentioned for Independent mode not mentioned the same table with PWM mode, so bit confusion.

    Hi ,

    Thank you for your questions. 

    PWM mode can be used for PWM motor operation. Please refer table 8-5

    As Table 8-5 shows, if IN1 has PWM signal input from MCU, DRV output PWM on OUT2. 

    Could you generate new E2E post to ask new questions? This post will be referred by someone in future. Would like to keep same question on one E2E post.

    regards

    Shinya
