SLVSCC0D November 2013 – October 2019 DRV8850
The current path is through the high-side sourcing DMOS power driver, motor winding, and low-side sinking DMOS power driver. Power dissipation losses in one source and sink DMOS power driver are shown in the following equation.
The DRV8850 has been measured to be capable of 5-A RMS current at 25°C on standard FR-4 PCBs. The maximum RMS current varies based on PCB design and the ambient temperature.
