This reference design demonstrates a high-efficiency 320-VDC input, three-phase power stage using six fast switching GaN-FETs with integrated driver, protection and temperature reporting with hot-side microcontroller control, especially for motor-integrated servo drives and robotics applications. Accurate phase-current sensing is achieved with isolated delta-sigma modulators. The DC-link voltage is measured with a non-isolated small form-factor delta-sigma modulator and an analog phase voltage feedback option allows validation of advanced sensorless designs like InstaSPIN-FOC™. For easy evaluation, this design offers a 3.3-V I/O interface signal with a 180-pin connector for C2000™ microcontroller controlCARDs, as well as a standard header to connect to other microcontrollers, such as the Sitara™ AM2631.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
