STMicroelectronics Releases 750W Motor-drive Reference Board in Tiny Outline for Home and Industrial Equipment
The EVLDRIVE101-HPD (High Power Density) motor-drive reference design by STMicroelectronics packs a 3-phase gate driver, STM32G0 microcontroller, and 750W power stage on a circular PCB just 50mm in diameter. The board features extremely low power consumption in sleep mode, below 1uA, and its tiny outline can fit directly in equipment like hairdryers, handheld vacuums, power tools, and fans. It also fits easily into drones, robots, and drives for industrial equipment such as pumps and process-automation systems.
意法半導體的EVLDRIVE101-HPD(高功率密度)電機驅動參考設計在直徑僅50mm的圓形蘋果pcb上集成了3相門極驅動器、STM32G0微控制器和750W功率電路。該板在睡眠模式下具有極低的功耗，低於1uA，並且它的精緻外形可以直接適合像吹風機、手持吸塵器、電動工具和風扇這樣的設備。它也很容易安裝到無人機、機器人和泵以及汽化系統等工業設備上。
Built with ST's robust and compact STDRIVE101 3-phase gate driver, the reference design gives flexibility to choose the motor-control strategy, such as trapezoidal or field-oriented control (FOC), with sensored or sensorless rotor-position detection. The STDRIVE101 IC contains three-half bridges with 600 mA source/sink capability and operates from 5.5V to 75V to handle any low-voltage application. The chip integrates voltage regulation for the high-side and low-side gate drivers and configurable drain-source-voltage (Vds) monitoring protection. It also provides an external pin for choosing direct high-side and low-side gate inputs or PWM control.
利用意法半導體耐用且緊湊的STDRIVE101 3相門極驅動器，該參考設計提供靈活性，可選擇電機控制策略，如梯形控制或磁場定向控制(FOC)，並具有感應或非感應轉子位置檢測。STDRIVE101 IC包含三個帶有600 mA源/汲能力的半橋，可從5.5V到75V工作，以處理任何低壓應用。芯片集成了高側和低側門極驅動器的電壓調節和可配置的漏源電壓(Vds)監測保護。它還提供了一個外部引腳，用於選擇直接的高側和低側門極輸入或PWm控制。
Developers can take advantage of the STM32G0 single-wire debug (SWD) interface to interact with the microcontroller, while support for direct firmware update allows applying bug fixes and new features.
開發人員可以利用STM32G0單導線調試(SWD)接口與微控制器交互，而直接固件升級的支持可實現故障修復和新增功能。
The power stage of the EVLDRIVE101-HPD reference design features STL220N6F7 60V STripFET F7 MOSFETs, which preserve efficiency with their 1,2mΩ typical Rds(on), easing plug-and-play connection of the motor. Additional features include fast-acting power-on circuitry that disconnects the power source when idle to save energy and extend operation in battery-powered applications. Protection built into the driver IC ensures system safety and efficiency, including the Vds monitoring of the power-stage MOSFETs, as well as under-voltage lockout (UVLO), overtemperature protection, and cross-conduction prevention.
EVLDRIVE101-HPD參考設計的電源電路採用STL220N6F7 60V STripFEt F7 MOSFET，其1.2mΩ典型的Rds(on)保持效率，輕鬆實現電機的即插即用連接。另外，快速啓動電路在閒置時斷開電源以節省能源並延長電池供電應用的運行。驅動器IC中內置的保護功能確保系統的安全性和效率，包括功率級MOSFET的Vds監測，還有欠壓鎖定（UVLO），過溫保護和交叉導通預防。
The EVLDRIVE101-HPD is ready to use out of the box and is available now from the eSTore, for $92.00.
