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

用于工業(yè)應(yīng)用和家用電器的新型STSPIN32G0系列電機(jī)驅(qū)動(dòng)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(dǎo)體的STSPIN32驅(qū)動(dòng)器將通用STM32微控制器 (MCU) 與功能豐富的三相柵極驅(qū)動(dòng)器相結(jié)合，不僅簡(jiǎn)化了設(shè)計(jì)，節(jié)省了PCB面積，還加快了上市時(shí)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(dòng)器，適用于電池供電的電器和電動(dòng)工具、工業(yè)自動(dòng)化、機(jī)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(jì)算能力，包括六步控制和磁場(chǎng)定向控制 (FOC)?？赏ㄟ^(guò)單/雙/三電阻拓?fù)錈o(wú)感或有感方式來(lái)實(shí)現(xiàn)FOC。有助于簡(jiǎn)化系統(tǒng)設(shè)計(jì)的其他功能包括：12位ADC、內(nèi)部電壓參考緩沖器、高級(jí)電機(jī)控制定時(shí)器，以及包括I2C、USART和SPI在內(nèi)的數(shù)字接口。多達(dá)32個(gè)通用I/O引腳 (GPIO)、64KB Flash和8KB SRAM為開(kāi)發(fā)者提供了托管復(fù)雜應(yīng)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(dòng)器，適用于高達(dá)36V的鋰電池或者工業(yè)總線等電源供電的應(yīng)用。相關(guān)示例包含便攜式電動(dòng)工具和電器、無(wú)繩真空吸塵器、機(jī)器人、風(fēng)扇和泵。四款產(chǎn)品包含了模擬信號(hào)輸入、GPIO和專(zhuān)用模擬參考電壓引腳的不同組合。所有驅(qū)動(dòng)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(shè)備供電），使四款器件均能實(shí)現(xiàn)自供電。
