➀ This article introduces a 12V-60V three-phase GaN inverter reference design from Texas Instruments, which focuses on high efficiency, precise current sensing, and sensorless control for robotics and motor drives.
➁ The design uses three LMG2100R044 GaN half-bridge modules, each capable of handling 100V and 35A, integrating GaN FETs, drivers, and bootstrap diodes to optimize switching performance and reduce parasitic inductance.
➂ Key features include precise current measurement with a 1mΩ shunt resistor and INA241 current sense amplifier, compatibility with C2000 MCUs via a TI BoosterPack compatible interface, and suitability for applications such as robotic servo drives and drone accessories.
