STMicroelectronics has launched the new EVSPIN32G4-DUAL demonstration board that controls two motors from a single STSPIN32G4 integrated driver, accelerating product development and simplifying the PCB design and bill of materials. The EVSPIN32G4-DUAL board cuts the time to market for advanced industrial and consumer products such as robots, multi-axis factory automation systems, garden equipment, and power tools. The STSPIN32G4 motor controller contains an Arm® Cortex®-M4 microcontroller (MCU) with the processing power to manage both motors simultaneously, executing complex algorithms like field-oriented control (FOC) in real-time.
The EVSPIN32G4-DUAL demonstration board leverages an advanced three-phase gate driver integrated in the STSPIN32G4 and an additional STDRIVE101 gate driver to control two three-phase inverters delivering up to 10A with a maximum supply voltage of 74V. Both gate drivers have their own bootstrap circuitry and safety features including drain-source voltage monitoring, cross-conduction prevention, several thermal protection mechanisms, and under-voltage lockout (UVLO).
It also leverages the STSPIN32G4’s built-in power-management circuitry, permitting a compact design with a low BOM that is easy to procure and permits rapid assembly in production. The power management includes a programmable buck converter for gate drivers VCC supply, a low-dropout linear regulator, and a special regulator with low quiescent current to supply the MCU during standby.
