意法半导体推出两款600伏三相栅极驱动器：千片起售价1.49美元、现已量产
意法半导体于2026年11月12日在瑞士日内瓦发布产品稿，为其STDRIVE三相栅极驱动器家族新增两款600伏器件STDRIVE631P与STDRIVE631N，使电机驱动与逆变器可直接在高压母线上工作。两款器件在紧凑的SO-28封装内集成三组半桥驱动，驱动N沟道功率MOSFET或IGBT，应用包括风机、水泵与白色家电压缩机。
公司称两款器件采用先进的BCD6-OFFLINE工艺，输出可提供1.0安培拉电流与0.85安培灌电流，可承受高达100伏的地电位以下尖峰，每路输出集成零压降自举二极管，各通道传播延迟相互匹配。STDRIVE631P采用正逻辑即高电平有效输入，STDRIVE631N采用负逻辑即低电平有效输入。保护功能包括带智能关断的集成比较器，用于处理过流与过温等故障，另有互锁与死区控制防止直通，低侧与高侧驱动部分均设欠压锁定。
公司称两款器件的瞬态抗扰度为正负50伏每纳秒，可承受高达2千伏的人体模型静电放电事件。配套评估板EVLSTDRIVE631P与EVLSTDRIVE631N同步提供，每块板含一套以STGD6M65DF2 IGBT搭建的完整三相逆变器，可选单电阻或三电阻电流采样，并经34针电机控制连接器与STM32微控制器接口。两款器件现已量产，工作温度范围为零下40摄氏度至125摄氏度，1000片起订价1.49美元起。
STMicroelectronics Adds Two 600V Three-Phase Gate Drivers: Priced From 1.49 Dollars per 1,000 Pieces and Now in Production
STMicroelectronics extended its STDRIVE family of three-phase gate drivers on November 12, 2026, in a company release issued from Geneva, Switzerland, with two new 600V devices, the STDRIVE631P and the STDRIVE631N, that let motor drives and inverters operate directly from a high-voltage bus. The two devices integrate three half-bridge drivers for N-channel power MOSFETs or IGBTs in a compact SO-28 package, for applications such as fans, pumps and compressors for white goods.
The company said both devices use its BCD6-OFFLINE technology, with outputs capable of sourcing 1.0A and sinking 0.85A and robustness to below-ground spikes of up to 100V. Each output integrates a zero-drop bootstrap diode, and propagation delays are matched for all channels. The STDRIVE631P uses positive, active-high input logic, while the STDRIVE631N uses negative, active-low logic. Protection includes an integrated comparator with smart shutdown for faults such as overcurrent and overtemperature, interlocking and deadtime control to prevent cross conduction, and under-voltage lock-out for the low-side and high-side driving sections.
The company said the devices provide plus or minus 50V per nanosecond of dV/dt transient immunity and protection against electrostatic discharge events of up to 2kV under the human body model. Evaluation boards EVLSTDRIVE631P and EVLSTDRIVE631N are also available, each containing a complete three-phase inverter built with STGD6M65DF2 IGBTs, with selectable single- or three-shunt current sensing and a 34-pin motor-control connector for STM32 microcontrollers. Both devices are in production now, rated for minus 40 degrees Celsius to 125 degrees Celsius, with pricing starting from 1.49 dollars for orders of 1,000 pieces.
