IR AUIRS20302S三相600W BLDC马达驱动方案
IR公司的AUIRS20302S是专用于BLDC马达驱动的三相栅极驱动器,驱动功率高达600W的BLDC马达,工作定压高达+200V,三个通路都有欠压锁住,防止交叉导通的逻辑电路,3.3V逻辑兼容,集成了电流检测的比较器,加电复位架构,具有汽车级的质量,主要用在24V-150V三相马达驱动,汽车和卡车HVAC和泵,BLDC马达驱动.本文介绍了AUIRS20302S主要特性,框图,典型应用电路以及100W 24V BLDC马达驱动电路图B元件布局图.
The AUIRS20302S is a three phase gate driver dedicated to BLDC motor drive up to 600W. Proprietary HVIC technology enables this rugged monolithic design with enforced Automotive ESD & Latch-up grades. Primarily designed for 24V battery application, its drive capability goes from 12v to 200V which cover all the abnormal conditions of the vehicle. The gate drive circuitry features cross-conduction preventive and minimum dead-time blocks. It is powered by a constant voltage so that the gate drives never exceed 17V including during Load Dump condition.
