hello
What is the efficiency of the DRV8035-Q1part ? ( My motor work in 12V -> 200mA in stady state).
I didn't find any remarks regarding the efficiency in data sheet.

Hi Roi,
By efficency i am assumeing you mean the efficency of the DRV8305-Q1 with the FETs as a system and not just the DRV8305-Q1. The efficiency of the DRV8305-Q1 and FETs depends on PWM frequency, FET gate capacitance and your motor voltage. The easiest way to measure the efficiency quickly would be to not attach the motor and then apply commutation signals to the DRV8305-Q1 like you are driving a motor and observer the current draw.
