I. Key Details of the EVSPIN32G4-DUAL Demo Board

The EVSPIN32G4-DUAL is a professional demo board launched by STMicroelectronics, It features the STSPIN32G4 high-performance three-phase motor controller and the STDRIVE101 three-half-bridge gate driver. Designed specifically for evaluating dual BLDC motor drive solutions and verifying the functionality of related components, it can simultaneously drive two three-phase brushless motors. Widely used in R&D testing and technical demonstrations across industrial control, smart home, power tools, and electric vehicles, it helps engineers quickly familiarize themselves with device characteristics, optimize drive algorithms, and accelerate product development.

(1) Core Components

- Core Control and Drive Devices: Equipped with two core devices—the STSPIN32G4 and STDRIVE101. The STSPIN32G4 features a 9x9 mm VFQFPN package and is a system-in-package (SiP) device that integrates a high-performance three-half-bridge gate driver with an STM32G431 microcontroller; The STDRIVE101, housed in a compact 4x4 mm VFQFPN package, is a three-half-bridge gate driver. Together, these two components enable efficient drive and precise control of dual BLDC motors.

- Power Stage Configuration: Both power stages are based on the STL110N10F7 power MOSFET, capable of delivering up to 10 A of output current and operating synchronously at a supply voltage of 74 V. This provides stable and sufficient drive power for the dual BLDC motors, while also featuring dedicated temperature and bus voltage monitoring, power MOSFET drain-source voltage detection, and overcurrent protection.

- Control and Feedback Module: Supports sensorless operation via single-shunt current sensing (utilizing the internal operational amplifier of the STSPIN32G4). It also features dedicated feedback input interfaces for each motor, compatible with Hall sensors, incremental quadrature encoders, and absolute encoders with SSI communication interfaces, meeting the requirements for deploying sensor-based control algorithms.

- Power Supply and Debugging Module: Integrates a voltage regulator; the gate driver and control logic power supplies can be powered directly from the motor power supply without requiring dedicated circuits; features on-board debugging interfaces to support firmware upgrades and functional debugging; also includes an NTC sensor for power stage temperature monitoring.

- Communication and Expansion Interfaces: Pre-configured CAN bus interface allows for easy connection to master or slave device modules to build complex motion control systems; also equipped with a full suite of communication interfaces including I²C, SPI, and UART to meet diverse communication and expansion needs.

(II) Core Component Features and Demonstration Board Advantages

1. Core Component Features

- STSPIN32G4: Embedded STM32G431 microcontroller (32-bit Arm Cortex-M4 core + FPU, clock frequency up to 170 MHz), integrating 128 KB of Flash memory and 32 KB of SRAM. It features two 16-bit advanced timers for motor control, two 12-bit ADCs (conversion rate 4 Msps), and a gate driver rated at 75 V with a sink/ source current of 1 A, integrated bootstrap diodes and a full suite of protection features, supports multiple motor control algorithms, and enables single- or dual-motor control.

- STDRIVE101: Gate driver rated at 75 V, sink/ source current of 600 mA, integrated bootstrap diode, supports two input strategies: ENx/INx (adjustable dead-time generation) and INHx/INLx (interlock function), propagation delay of only 40 ns, excellent channel-to-channel matching, integrated 12 V LDO linear regulator, overcurrent comparator, as well as UVLO (undervoltage lockout) and thermal shutdown protection, supports standby mode to reduce power consumption.

2. Key Advantages of the Demo Board

- Efficient Dual Motor Drive: Capable of simultaneously driving two BLDC motors with independent bus voltage ranges from 10 V to 74 V. Supports both sensorless and sensor-based control modes to meet diverse motor control requirements.

- High Integration and Reliability: The core components feature high integration, simplifying hardware design, while offering comprehensive protection functions (thermal shutdown, short-circuit, overload, UVLO, etc.). It operates stably in environments ranging from -40°C to +125°C, making it suitable for harsh industrial environments.

- Convenient R&D and Debugging: Official technical resources (schematics, BOM, firmware source files, etc.) are provided. On-board debugging interfaces support the deployment of various motor control algorithms, allowing for immediate device evaluation and functional demonstrations right out of the box, thereby shortening the R&D cycle.

- Flexible Expansion: Pre-configured CAN bus and multiple communication interfaces enable easy integration into complex motion control systems, meeting diverse expansion needs across various application scenarios.
