Hi,
We are currently working on implementing the DRV8873 in one of our designs. We are using the DRV8873S to control a (permanent magnet) brushed DC motor. Our application requires that the motor driver can sense a load at the output or a open connection (Hi-Z). The application software is anticipating to that.
During testing of the DRV8873S + motor we used the GUI software provided with the EVM kit. We are encountering a problem with the Open load detection (OLD). We have a few questions:
- The passive OLD bit is not flipped of the motor is disconnected while unpowered. How can we use passive OLD?
- When we use active OLD the OLD bit is [0], but when de motor spins up the bit becomes [1]. the motor is still spinning.
Would you recommend a different motor driver? We need something for 24V 3A
Thank you
