EVLGANSPIN1-3PH [STMicroelectronics]

The EVLGANSPIN1-3PH is a three-phase inverter based on the GANSPIN611 half-bridge GaN system-in-package (integrating 138 mΩ 650 V e-mode HEMT GaN and the gate driver with LDOs, bootstrap diode, overcurrent protection) and the STM32G431RB with Arm Cortex®-M4 MCU at 170 MHz with 128 Kbytes of Flash memory, Math Accelerator.

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 EVLGANSPIN1-3PH is 77 x 88 mm wide, 4 layers, 2 Oz, FR-4 PCB, resulting in overall 12 °C/W Rth(J‑A) (equivalent to 72°C/W for each GaN and 32 °C/W for each half-bridge) in still air.
