This design guide demonstrates a 36V, 50A Gallium nitride (GaN) field-effect transistor (FET) power stage for driving a three-phase brushless DC motor in cordless tools operating from a 5-cell Li-ion battery to a 10-cell battery pack. This reference design uses the LMG3100R017 GaN FET with integrated GaN-FET drive to improve the motor control system efficiency and performance. Additionally, the design offers a TI BoosterPack™ Plug-in Module compatible with 3.3V I/O interface that can connect to a C2000™ MCU LaunchPad™ development kit or MSPM0 MCU LaunchPad™ development kit for quick and easy performance evaluation of TI's GaN technology.
