  • DRV8704: Can the DRV8704 be used to drive a Peliter device for heating and cooling.

    Resolved
    Part Number: DRV8704 Other Parts Discussed in Thread: DRV8412 , The ideal application would involve driving the AIN1 and AIN2 in anti-phase with 50% duty cycle representing zero current. The two outputs would sit at mid-rail. As the duty cycle is changed…
