Hi Avraham,

Yes you can reduce Rsense , that's no DRV110 limitation since all power is externally dissipated. The external FET is the main limitation

The IR drop across Rsense should be>30mV for good Ipeak;Ihold accuracy

Hi Avraham,

I haven’t heard back from you, I’m assuming you were able to resolve your issue. If not, just post a reply below (or create a new thread if the thread has locked due to time-out)
