750W motor-drive reference board in tiny outline for home and industrial equipment

外形小巧的750W電機(jī)驅(qū)動參考板，面向家庭和工業(yè)設(shè)備應(yīng)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）電機(jī)驅(qū)動器參考設(shè)計在直徑僅為50mm的圓形PCB上封裝了三相柵極驅(qū)動器、STM32G0微控制器和750W功率級。該板在睡眠模式下的功耗極低（低于1uA），其微小的尺寸可直接安裝在吹風(fēng)機(jī)、手持吸塵器、電動工具和風(fēng)扇等設(shè)備中。不僅如此，該板也能方便地安裝到無人機(jī)、機(jī)器人和工業(yè)設(shè)備（如泵和過程自動化系統(tǒng)）的驅(qū)動器中。

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.

該參考設(shè)計采用意法半導(dǎo)體穩(wěn)健、緊湊的STDRIVE101三相門驅(qū)動器構(gòu)建，可靈活選擇電機(jī)控制策略，如梯形波或磁場定向控制 (FOC)，支持有感或無感轉(zhuǎn)子位置檢測功能。STDRIVE101 IC包含三個半橋驅(qū)動器，其具有600mA的拉電/灌電流能力，只用于工作電壓為5.5V至75V的任何低壓應(yīng)用。芯片集成了高邊和低邊柵極驅(qū)動器的電源以及可配置的漏源電壓 (Vds) 監(jiān)測保護(hù)。此外，它還提供了一個外部引腳，用于選擇直接的高邊和低邊柵極輸入或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(fā)者可利用STM32G0單線調(diào)試 (SWD) 接口與微控制器進(jìn)行交互，同時支持直接固件更新，允許應(yīng)用錯誤修復(fù)和新功能。

The power stage of the EVLDRIVE101-HPD reference design features STL220N6F7 60V STripFET F7 MOSFETs, which preserve efficiency with their 1,2m? 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(shè)計的功率級采用STL220N6F7 60V STripFET F7 MOSFET，其1.2m?的典型Rds(on)不僅保證了效率，還簡化了電機(jī)的即插即用連接。其他功能包括快速通電電路，該電路在空閑時將斷開電源，以節(jié)省能源并延長電池供電應(yīng)用的運(yùn)行時間。驅(qū)動器IC內(nèi)置的保護(hù)功能可保障系統(tǒng)的安全性和效率，包括功率級MOSFET的Vds監(jiān)測，以及欠壓鎖定 (UVLO)、過熱保護(hù)和防交叉導(dǎo)通功能。
