[原创] Silabs Si828x系列具系统安全特性的4A IGBT驱动方案

Silabs公司的Si828x系列(Si8285和Si8286)是集成了系统安全性和反馈功能的隔离的大电流(4A)栅极驱动器,支持UL1577的高达5.0kVrms的耐压,主要用在IGBT/MOSFET栅极驱动,工业,HEV和可再生能源逆变器,AC,无刷和DC马达驱动与控制,白色家电中变速马达控制,以及隔离的开关电源和UPS电源.本文介绍了Si828x系列(Si8285和Si8286)主要特性,Si8285/6应用电路图,评估板Si8285/86-EVB主要特性,电路图和材料清单以及PCB设计图.

The Si828x (Si8285 and Si8286) are isolated, high current gate drivers with integrated system safety and feedback function. The devices are ideal for driving power MOSFETs and IGBTs used in a wide variety of inverter and motor control applications. The Si8285 and Si8286 isolated gate drivers utilize Silicon Labs’proprietary silicon isolation technology,supporting up to 5.0 kVrms withstand voltage per UL1577. This technology enableshigher-performance, reduced variation with temperature and age, tighter part-to-partmatching, and superior common-mode rejection compared to other isolated gate drivertechnologies.
