Motordriver Board v6.4

The 2025–2026 motor driver board was all about leveling up from last year’s design. We kicked things off by building a gate driver circuit in LTSpice, running simulations to test and refine the design before bringing it to life in hardware.

Gate Driver Simulations

LTSpice

I designed a gate driver circuit to control a half-bridge setup, delivering a PWM signal switching between 24V and 0V. The circuit uses a bipolar totem-pole configuration as a push-pull stage to drive the high-side gate while maintaining a steady current flow. After building the circuit, I successfully debugged it, ensuring reliable operation and performance.
