The new STSPIN32G0 series from STMicroelectronics are highly integrated motor controller systems-in-package (SiPs) for driving three-phase motors.
The STSPIN32G0 SIPs integrate a gate driver rated for 250 V or 600 V and a STM32G0 microcontroller based on a 64 MHz Arm® Cortex®-M0+ core. The built-in MCU has sufficient computing power to handle popular motor algorithms such as six-step and field-oriented control (FOC).
These compact motor controllers enable motor system designers to realize designs with a substantially smaller board footprint than comparable designs based on discrete motor drivers and controllers, without compromising performance or robustness.
The four motor controllers in the STSPIN32G0 series are
STSPIN32G0251: a 250 V three-phase driver with STM32 controller. Maximum output voltage of 250 V, and gate current of 0.35 A.
STSPIN32G0252: a 250 V three-phase driver with STM32 controller. Maximum output voltage of 250 V, and gate current of 0.85 A.
STSPIN32G0601: a 600 V three-phase driver with STM32 controller. Maximum output voltage of 600 V, and gate current of 0.35 A.
STSPIN32G0602: a 600 V three-phase driver with STM32 controller. Maximum output voltage of 600 V, and gate current of 0.85 A.
All members of the STSPIN32G0 series are supported by a rich set of hardware and software resources, including the X-CUBE-MCSDK motor control software development kit (SDK). The latest version 6.3 of the SDK includes a new Workbench tool, featuring a modern user interface with a fully reworked use flow. This new UI guides the designer through every phase of the motor configuration process.
Part Number: EVSPIN32G06Q1S1
The EVSPIN32G06Q1S1 board from STMicroelectronics is a complete three-phase inverter based on the STSPIN32G0601 controller, which integrates a three‑phase 600 V gate driver and an Arm® Cortex®-M0+ microcontroller. It is suitable for loads up to around 250 W, and drawing a 1 Arms phase current.
The power stage features STGD6M65DF2 IGBTs, but can be populated with any IGBT or power MOSFET in a DPAK or powerFLAT 8×8 HV package. The board has a single-shunt sensing topology, and supports both field-oriented control and six‑step control algorithms in either sensored or sensorless mode. This means that the board can drive permanent magnet synchronous motors (PMSMs) and brushless dc (BLDC) motors.
The evaluation board is compatible with a wide input-voltage range from 35 V ac/50 V dc to 280 V ac/400 V dc. It includes a power-supply stage based on the VIPER06XS offline power converter in flyback configuration to generate the +15 V and +3.3 V supply voltage required by the application.
