DRV8343H-Q1EVM: GAIN is floating and the current gain ratio is only 10

Cherry Zhou

Part Number: DRV8343H-Q1EVM

Hi Team,

The DRV8342H is configured in hardware with GAIN floating and a current gain ratio of only 10. By connecting GAIN to 0, the current gain is only 2.5, which is twice the overall gain described in the manual.

Could you please help look into this issue? Thanks.

Best Regards,

Cherry

Hi Cherry,

I discussed your issue with my team and we may not be understanding the issue fully.

How is Gain being calculated (what formula are you using), meaning how did you come to the conclusion that you are only getting a gain of 10 or 2.5?
