概述

     早期的电梯控制系统控制主板和变频器都是相对独立的，电气走线和调试都相对麻烦，一体机就是把控制主板和变频器有机糅合在一起了，线路就简单多了，调试也容易很多。电梯变频一体机是将大功率器件与散热技术很好的结合，具有成本低、体积小巧，结构紧凑、安装方便等优势，

　　优势

　　• 总线隔离器(Si8641/Si8621)采用先进的电容耦合和OOK调制技术实现电容隔离技术，0.25um CMOS技术工艺保证了在电梯变频一体机产品中使用隔离器的可靠性，与T牌、A牌类似产品比较，具有更高的EMC效果和超高性价比;

Low-Power Quad-Channel Digital Isolators

Silicon Lab's family of ultra-low-power digital isolators are CMOS devices offering substantialdata rate, propagation delay, power, size, reliability, and external BOM advantagesover legacy isolation technologies. The operating parameters of these productsremain stable across wide temperature ranges and throughout device service life forease of design and highly uniform performance. All device versions have Schmitt trigger inputs for high noise immunity and only require VDD bypass capacitors.

Data rates up to 150 Mbps are supported, and all devices achieve propagation delays of less than 10 ns. Enable inputs provide a single point control for enabling and disabling output drive. Ordering options include a choice of isolation ratings (1.0, 2.5, 3.75 and 5kV) and a selectable fail-safe operating mode to control the default output state during power loss. All products >1 kV are safety certified by UL, CSA, VDE, and CQC, and products in wide-body packages support reinforced insulation withstanding up to 5kVRMS.

Automotive Grade is available for certain part numbers. These products are built usingautomotive-specific flows at all steps in the manufacturing process to ensure the robustness and low defectivity required for automotive applications.
