DRV8306: Removing Sense resister

Part Number: DRV8306

Hi team,

My customer wants to remove sense resister of DRV8306 since they have another external current limit circuit.

Is it possible to connect ISEN pin to GND directly? 

SEN_OCP and CBC_CL won't work, but they say it won't be matter in their circuit.

Regards,

Takashi Onawa

    Onawa-San,

    If you have many questions on the same device and same customer, you can make one post instead of many posts.

    Yes this is fine you can connect it directly to GND but please make sure it's connected close to the source of the low side FETs.

    Regards,
