The SparkFun 3-Phase Brushless Motor Driver incorporates the TMC6300 from ADI + Trinamic, making it a robust and user-friendly driver for three-phase motors, specifically designed for our Brushless Gimbal Motor. It offers the capability to control any 3-phase BLDC or PMSM motor with a maximum total drive current of 2A (1.4ARMS). The driver allows separate high-side and low-side control of the three half-bridges, enabling precise management of each phase during motor commutation. Additionally, it includes safeguards against temperature variations and short circuits, along with a diagnostic output that signals any system faults. The TMC6300 operates with a regulated power output of 1.8V and can function with an input voltage as low as 2V, making it well-suited for low-power microcontroller and battery-powered designs. It can be powered by a minimum of two AA/NiMh cells or one to two Li-Ion cells.
