This reference design demonstrates a high-power density 12V to 60V 3-phase power stage using three LMG2100R044 100V, 35A GaN half-bridges with integrated GaN FETs, driver and bootstrap diode specifically for motor-integrated servo drives and robotics applications.
Accurate phase-current sensing is achieved through the IN241A current sense amplifier, DC-link and phase voltages are also measured allowing validation of advanced sensorless designs, such as the InstaSPIN-FOC™. The design offers a TI BoosterPack compatible 3.3-V I/O interface to connect to a C2000™ MCU LaunchPad™ development kit or Sitara™ microcontrollers for quick and easy performance evaluation of our GaN technology.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
