New STSPIN32G0 series of motor drivers for industrial applications and home appliances

用于工業(yè)應用和家用電器的新型STSPIN32G0系列電機驅(qū)動器

ST’s STSPIN32 drivers combine a general-purpose STM32 microcontroller (MCU) with a feature-rich three-phase gate driver to simplify design, save PCB area and accelerate time to market. The eight new STSPIN32G0 devices contain gate drivers rated 45V, 250V and 600V, targeting applications from battery-operated appliances and power tools to industrial automation, robots, HVAC systems and line-powered home appliances.

意法半導體的STSPIN32驅(qū)動器將通用STM32微控制器 (MCU) 與功能豐富的三相柵極驅(qū)動器相結(jié)合，不僅簡化了設計，節(jié)省了PCB面積，還加快了上市時間。八款全新STSPIN32G0器件包含額定電壓為45V、250V和600V的柵極驅(qū)動器，適用于電池供電的電器和電動工具、工業(yè)自動化、機器人、HVAC系統(tǒng)和線路供電的家用電器。

The new devices integrate an STM32G031 microcontroller, based on the Arm® Cortex®-M0+ core, which has the computing power to handle popular control algorithms, including six-step control and field-oriented control (FOC). FOC implementation can be sensored or sensorless, with one, two, or three shunts. Additional features that help simplify system design include a 12-bit ADC, internal voltage reference buffer, an advanced motor-control timer, and digital interfaces including I2C, USART, and SPI. Up to 32 general-purpose I/O pins (GPIOs), 64KB of Flash, and 8KB of SRAM give developers flexibility to host complex applications and innovate value-added features.

新器件集成了基于Arm® Cortex®-M0+內(nèi)核的STM32G031微控制器，該微控制器具有處理流行控制算法的計算能力，包括六步控制和磁場定向控制 (FOC)?？赏ㄟ^單/雙/三電阻拓撲無感或有感方式來實現(xiàn)FOC。有助于簡化系統(tǒng)設計的其他功能包括：12位ADC、內(nèi)部電壓參考緩沖器、高級電機控制定時器，以及包括I2C、USART和SPI在內(nèi)的數(shù)字接口。多達32個通用I/O引腳 (GPIO)、64KB Flash和8KB SRAM為開發(fā)者提供了托管復雜應用和創(chuàng)新增值功能的靈活性。

The four new low-voltage variants are based on a feature-rich 45V gate driver suitable for applications powered from sources such as lithium battery packs or industrial buses up to 36V. Examples include portable power tools and appliances, cordless vacuum cleaners, robots, fans and pumps. The four product variants offer different combinations of analog sensing inputs, GPIOs, and dedicated analog reference-voltage pins. All drivers have 600mA source/sink current capability and also integrate a 3.3V DC/DC converter and 12V linear regulator to power internal circuitry and external devices, making these four devices self-supplied.

四款全新低壓產(chǎn)品是基于功能豐富的45V柵極驅(qū)動器，適用于高達36V的鋰電池或者工業(yè)總線等電源供電的應用。相關示例包含便攜式電動工具和電器、無繩真空吸塵器、機器人、風扇和泵。四款產(chǎn)品包含了模擬信號輸入、GPIO和專用模擬參考電壓引腳的不同組合。所有驅(qū)動器均具有600mA的拉/灌電流能力，此外還集成了3.3V DC/DC轉(zhuǎn)換器和12V線性穩(wěn)壓器（用于為內(nèi)部電路和外部設備供電），使四款器件均能實現(xiàn)自供電。

The four high-voltage variants present a choice of 250V or 600V driver voltage rating and 200mA/350mA or 1.0A/0.85A source/sink current capability. All have ST SmartShutDown capability to guarantee fast protection of the external power stage in case of a fault. They are intended for applications such as home appliances, air conditioners, home and industrial refrigerators, industrial pumps and industrial automation.

All STSPIN32G0 devices integrate circuit protection including overcurrent and overload protection, cross-conduction prevention, and undervoltage lockout to ensure system safety and help further simplify the design.

所有STSPIN32G0器件均集成了電路保護，包括過電流和過載保護、防止交叉導通和欠壓鎖定，以確保系統(tǒng)安全，并有助于進一步簡化設計。

An evaluation board is available for each variant, which enables a fast start to new designs and all STSPIN32 family members connect users with the STM32 MCU development ecosystem. This provides an extensive selection of tools, software, and evaluation boards including the X-CUBE-MCSDK motor-control software development kit (SDK) with parameterizable firmware libraries and motor-control workbench GUI. There are also MCU-specific software packs and middleware, and the STM32CubeMX configurator that facilitates project setup and performance analysis.
