EVSTDRVG611MC [STMicroelectronics]

The EVSTDRVG611MC is a three-phase inverter based on the STDRIVEG611 half-bridge GaN gate driver, 75 mΩ 650 V e-mode HEMT GaN SGT120R65AL, and the high-performance STM32G431RBT3 with Arm Cortex®-M4 MCU at 170 MHz.

The board can be used for sensorless field-oriented control (FOC), allowing driving permanent magnet synchronous motors (PMSMs) and brushless DC (BLDC) motors to cover a wide range of applications, such as refrigerator compressors, pumps, fans, and industrial appliances.

The EVSTDRVG611MC is 109 x 110 mm wide, 2 layers, 2 Oz, FR-4 PCB, resulting in overall 8.5 °C/W Rth(J‑A) (equivalent to 50°C/W for each GaN) in still air.
