STMicroelectronics EVSPIN32G02Q1S1

Overview

EVSPIN32G02Q1S1 from STMicroelectronics is a 3-phase inverter evaluation board based on the STSPIN32G0251Q controller IC, integrating a 250 V 3-phase gate driver and Cortex-M0+ MCU. It features STD17NF25 MOSFETs (V_DS = 250 V, R_DS(on) max = 0.165 Ω), single-shunt current sensing, and supports both sensored/sensorless FOC and 6-step BLDC/PMSM motor control up to 300 W - used for residential compressor and corded power tool drive validation.

For engineers reviewing the EVSPIN32G02Q1S1 datasheet, EVSPIN32G02Q1S1 pinout, EVSPIN32G02Q1S1 application, or EVSPIN32G02Q1S1 equivalent, this board enables rapid firmware development and motor control algorithm testing with STLINK-V3SET debug interface, Hall/encoder inputs, bus voltage sensing, and dual 12 V / 3.3 V regulated supplies derived from VIPer013BLS.

Technical Context

The board implements a complete 3-phase inverter functional chain: AC input (15–120 VAC) feeds a VIPer013BLS buck converter generating isolated 12 V and 3.3 V rails; STSPIN32G0251Q drives six STD17NF25 MOSFETs in DPAK package via high- and low-side gate drivers (LVG1–3, HVG1–3); current feedback uses a single-shunt topology with TSV991ILT op-amp and TS3021ILT comparator for overcurrent threshold at 4 A_peak.

Motor control flexibility is provided through configurable interfaces: digital Hall sensor inputs (A+/H1, B+/H2, Z+/H3), encoder support, BEMF detection network, SWD/UART/SPI headers, and user switches/trimmer for real-time tuning - all coordinated by the embedded STM32 MCU running preloaded FOC or 6-step firmware.

FAQ

Is EVSPIN32G02Q1S1 electrically isolated from the AC mains input?

No. The board has no galvanic isolation between AC/DC input and accessible circuits or USB interface. ST explicitly warns that the USB connection does not insulate the host PC from high voltage. When operating outside ELV (Extra-Low Voltage) range, a certified USB isolator must be used to prevent shock hazard during debugging.

What motor types and control methods does EVSPIN32G02Q1S1 support?

It supports permanent magnet synchronous motors (PMSMs) and brushless DC (BLDC) motors using either sensored (Hall/encoder) or sensorless implementations of both 6-step commutation and field-oriented control (FOC). Firmware examples for all four combinations are provided in ST's X-CUBE-MCSDK.

Can I replace the STD17NF25 MOSFETs with IGBTs or other MOSFETs?

Yes - the board supports dual footprint compatibility: DPAK for STD17NF25 and PowerFlat 8x8 HV for alternatives like STL24N60DM2. Gate driver outputs (LVG/HVG pins) and layout accommodate both packages, but thermal and switching performance must be revalidated per replacement device.

Does EVSPIN32G02Q1S1 include onboard current/voltage measurement capability?

Yes. It integrates bus voltage sensing (VBUS_fdbk), single-shunt current feedback (via CIN node and TSV991ILT amplifier), and temperature monitoring (NTC1). All analog signals route to STM32 ADC inputs, enabling real-time closed-loop control without external instrumentation.
