EVSPIN32F0251S1

The 3-phase inverter is based on the STSPIN32F0251 controller which embeds a 3‑phase 250V gate driver and a Cortex®‑M0 STM32 MCU. The power stage features STD17NF25 MOSFET but can be populated with any IGBT or power MOSFET in DPAK or powerFLAT 6x5 package. The board has a single shunt sensing topology and both the field oriented control (FOC) and sensored or sensorless 6‑step control can be implemented. This allows driving permanent magnet synchronous motors (PMSMs) and brushless DC (BLDC) motors. The evaluation board is compatible with a wide range input voltage from 20V to 120V DC/AC and includes a power supply stage with the VIPER013BLS in flyback configuration to generate +15V and +3.3V supply voltage required by the application. Typical applications include battery operated and 110VAC supplied power and garden tools, industrial fans and pumps, home appliances and industrial and home automation.
