I use two DRV8412 motor drivers in parallel full-bridge mode to drive brushed DC-motors. I use one DRV8412 (one half bridge in parallel full-bridge mode, AB) and another DRV8412 (also one half bridge in parallell full bridge mode, AB) to drive one dc motor. This failsafe concept work perfectly to drive the motor. My problem is that the other "open" half bridges of the two DRV8412 should be in high-impedance state. But when I pull the RESET_CD signals to GND then their full bridge of both drivers go into high-impedance state. The datasheet says that RESET_CD only effects the half bridge CD. I hope you can help me to find the problem.
With best regards
