RE: DRV8307: DRV 8307 driving 100%PWM when its pwm input is low
Hi Ashwini, Please note the last sentence of section 7.4.1 of the datasheet date February 2016: When the DRV8307 is driving a motor, the motor should not be stopped by setting the PWM input to 0% duty...

Hi, only because of interest - has anybody seen, that the VINT is connected to Ground. Is it possible? Or why should it be connected to VM? Best regards - Chris

Hello Chris, VINT pin should be connected to ground through a 2.2uF bypass capacitor. Thanks.

Hi Rick, yes you are right, it was my 'logical shortcut'. Nevertheless it is an interesting question for me: Why should I use a C from VCP to VM and NOT to Ground? Thank you Chris

Hi Chris, Connecting the C to VM instead of ground provides several benefits. Without going into all the details: There is less leakage in the capacitor when the charge pump is off. The voltage...
