Hi!

I am planning to use DRV8353 as a gate driver for my PMSM motor controller

But because of the high power, I cannot use Rsense to sense the phase current.

My question is can I use the hall current sensor to replace the Rsense

If it is possible, pls tell me how to do it

Thanks for reading

Hi Ryder,

Ryder,

Here is a link to our hall based current sensor solutions that can be used to replace a shunt. If you use a hall based sensor, than you no longer need the amplifiers in the DRV8353. I would then recommend a DRV8350 (no current shunt amplifiers) instead of the DRV8353.

Here is a reference design using a hall based solution for motor drive.
