ADI ADuM4137单路IGBT栅极驱动解决方案
ADI公司的ADuM4137是单路IGBT栅极驱动器,采用ADI的iCoupler®技术,使得输入信号和输出栅驱动之间绝缘.器件还对过流,遥控温度过热,欠压锁住(UVLO)和热关断(TSD)等事件提供故障报告.峰值驱动输出6A,NFET内部关断时开态电阻小于0.95Ω,PFET关断时开态电阻小于1.18Ω,上升传输时延105ns,下降传输时延107ns,最小脉冲宽度70ns,工作结温范围为−40℃到+150℃,满足汽车应用AEC-Q100规范,主要用在MOSFET/IGBT栅极驱动器,光伏(PV)逆变器,马达驱动和电源.本文介绍了ADuM4137主要特性,功能框图,IGBT驱动应用案例电路以及评估板EVAL-ADuM4137EBZ主要特性,电路图,材料清单和PCB设计图.
The ADuM41371 is a single-channel gate driver specifically optimized for driving insulated gate bipolar transistors (IGBTs). Analog Devices, Inc., iCoupler® technology provides isolation between the input signal and the output gate drive.
The Analog Devices chip scale transformers also provide isolated communication of control information between the high voltage and low voltage domains of the chip. Information on the status of the chip can be read back from the dedicated fault outputs. The ADuM4137 provides isolated fault reporting for overcurrent events, remote temperature overheating events, undervoltage lockout (UVLO), and thermal shutdown (TSD).
