RE: DRV8307: I have designed drv8307 motor driver as same as 8307EVM i finding large current drawn from customized board as compared to EVM board

Hi Adarsh,

Your input PWM frequency to our device is independent of the output PWM frequency (see section 7.4.1 on page 19 of the DRV8307 datasheet). 16 kHz input frequency should not be an issue.

Does the motor spin at all in your testing? Have you made sure the hall-sensors are correctly connected to your board? See section 8.1.1 of the DRV8307 datasheet for correct hall sensor configuration.
