Control BLDC motor using GaN GateDrivers with Teensy 4.1

[Rajashekhar]

Hi All,

I am exploring the use of a Teensy 4.1 to control a 3-phase BLDC motor through a GaN-based gate driver (such as solutions from TI, Onsemi, or Renesas).
My application requires either velocity control or torque control, with the eventual goal of using the same control architecture for a humanoid robotics platform.
I would appreciate hearing from anyone who has successfully implemented a similar setup. Specifically, I am interested in:

• The GaN gate driver IC/module used
• PWM generation and gate-driving approach
• BLDC control method (6-step, sinusoidal, FOC, etc.)
• Hall sensor or encoder feedback implementation
• Sample algorithms, example projects, or reference code for Teensy 4.1
• Any lessons learned regarding deadtime, switching frequency, current sensing, and protection mechanisms

If you have sample code, libraries, application notes, or project references that could help accelerate development, I would greatly appreciate it.
Thank you in advance for your guidance.

Best regards,
Rajashekhar
