TI,
I am looking to use the DRV8904-Q1 to operate 4 independent small motors uni-directional. I am assuming that I can use each channel of the DRV8904 to operate an individual motor via internal independent 8-bit PWM. I would connect motor + to a channel output and motor - to GND. I assume recirculation would always be available through the body diodes of the lowside FET of each half-bridge. I also assume each channel would provide independent short circuit and OLD features.
I want to confirm this since the datasheet always shows bidirectional motors connected to dual channels for full bridge operation. Figure 68 does show passive OLD in the configuration I need, but I want to confirm that I can do this with 4 independent half-bridge channels of the 8904.
Are my assumptions correct? Are there any caveats to using the 8904 in the manner i am describing?
Thank you.
