外形小巧的750W电机驱动参考板，面向家庭和工业设备应用

The EVLDRIVE101-HPD (High Power Density) motor-drive reference design 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.

EVLDRIVE101-HPD（高功率密度）电机驱动器参考设计在直径仅为50mm的圆形PCB上封装了三相栅极驱动器、STM32G0微控制器和750W功率级。该板在睡眠模式下的功耗极低（低于1uA），其微小的尺寸可直接安装在吹风机、手持吸尘器、电动工具和风扇等设备中。不仅如此，该板也能方便地安装到无人机、机器人和工业设备（如泵和过程自动化系统）的驱动器中。

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.

该参考设计采用意法半导体稳健、紧凑的STDRIVE101三相门驱动器构建，可灵活选择电机控制策略，如梯形波或磁场定向控制 (FOC)，支持有感或无感转子位置检测功能。STDRIVE101 IC包含三个半桥驱动器，其具有600mA的拉电/灌电流能力，只用于工作电压为5.5V至75V的任何低压应用。芯片集成了高边和低边栅极驱动器的电源以及可配置的漏源电压 (Vds) 监测保护。此外，它还提供了一个外部引脚，用于选择直接的高边和低边栅极输入或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.

开发者可利用STM32G0单线调试 (SWD) 接口与微控制器进行交互，同时支持直接固件更新，允许应用错误修复和新功能。

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参考设计的功率级采用STL220N6F7 60V STripFET F7 MOSFET，其1.2mΩ的典型Rds(on)不仅保证了效率，还简化了电机的即插即用连接。其他功能包括快速通电电路，该电路在空闲时将断开电源，以节省能源并延长电池供电应用的运行时间。驱动器IC内置的保护功能可保障系统的安全性和效率，包括功率级MOSFET的Vds监测，以及欠压锁定 (UVLO)、过热保护和防交叉导通功能。
