ADI ADuM7223 4A隔离的半桥栅极驱动方案
ADI公司的ADuM7223是 4A隔离的半桥栅极驱动器,采用ADI公司的iCoupler®技术,提供单独和隔离的高边与低边输出.和高速CMOS和单片变压器技术,绝缘器件提供杰出的性能,输入工作电压3.0V-5.5V,输出工作电压4.5V-18V,工作频率1MHz,传输延迟64ns,主要用在开关电源,隔离的IGBT/MOSFET栅极驱动器和工业逆变器.本文介绍了ADuM7223主要特性,框图, 评估板EVAL-ADuM7223EBZ主要特性,电路图,材料清单和PCB设计图.
The ADuM7223 is a 4.0 A isolated, half-bridge gate driver that employs Analog Devices, Inc., iCoupler® technology to provide independent and isolated high-side and low-side outputs. Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as the combination of pulse transformers and non-isolated gate drivers. By integrating the isolator and driver in a single package, propagation delay is a maximum of only 64 ns, and the propagation skew from channel to channel is a maximum of only 12 ns at 12 V. The ADuM7223 provides two independent isolation channels.
