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.
意法半导体的EVLDRIVE101-HPD(高功率密度)电机驱动参考设计在直径仅50mm的圆形苹果pcb上集成了3相门极驱动器、STM32G0微控制器和750W功率电路。该板在睡眠模式下具有极低的功耗，低于1uA，并且它的精致外形可以直接适合像吹风机、手持吸尘器、电动工具和风扇这样的设备。它也很容易安装到无人机、机器人和泵以及汽化系统等工业设备上。
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.
利用意法半导体耐用且紧凑的STDRIVE101 3相门极驱动器，该参考设计提供灵活性，可选择电机控制策略，如梯形控制或磁场定向控制(FOC)，并具有感应或非感应转子位置检测。STDRIVE101 IC包含三个带有600 mA源/汲能力的半桥，可从5.5V到75V工作，以处理任何低压应用。芯片集成了高侧和低侧门极驱动器的电压调节和可配置的漏源电压(Vds)监测保护。它还提供了一个外部引脚，用于选择直接的高侧和低侧门极输入或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.
开发人员可以利用STM32G0单导线调试(SWD)接口与微控制器交互，而直接固件升级的支持可实现故障修复和新增功能。
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参考设计的功率电路采用STL220N6F7 60V STripFEt F7 MOSFET，其1.2mΩ的典型Rds(on)可以保证效率，并且使电机的插拔连接更加容易。附加功能包括快速启动电路，在空闲时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内置的保护功能可确保系统安全和效率，包括功率级MOSFET的Vds监测、欠压锁定(UVLO)、过温保护和交叉导通预防。
The EVLDRIVE101-HPD is ready to use out of the box and is available now from the eSTore, for $92.00.
