Hi，

For drv8705-q1, the resistance of VDS is set to overcurrent monitors. What is the overcurrent corresponding to different VDS voltages?

Thank you for your answer.

Best regards,

Hello,

I think you are referring to the DRV8705H-Q1 which is the hardware variant and external resistors are used on the VDS pin to set up to 6 different levels. There is a table in the datasheet that specifies the 6 possible levels for the drain-to-source voltage across the external FETs. When this threshold is exceeded, an overcurrent fault will occur.

Table copied above from the datasheet for the levels.

Regards,

Ryan
