DRV8312: Reduction of Table 7-2 rows relative to earlier datasheet version

Ken Hayden

Part Number: DRV8312

I see that in datasheet version SLES256F , Table 7-2 has been shortened by several rows relative to earlier datasheet version SLES256E. What is the reason for this?  Is it perhaps because lower-current settings were found to be less predictable than thought at first?  If so, what tolerance is appropriate for resistor values up to 200K?

    Hey Ken,

    Thank you for your question. 

    We removed OC sections since there was a large deviation due to process and temperature resulting in devices tripping at lower OC than the expected threshold. Therefore please consult the updated table for max current. 

    Please consult section 8.2.1.2.4 Overcurrent Threshold for more guidance.

    Best,
    Akshay
