【应用】尺寸4mm×5mm的三通道数字隔离器NIRSP31助力充电桩设计，方案成本降低＞15%
随着国家政策的大力支持：不限行、波谷电费、减免购置税等出台，越来越多的人会去购买电车。电车电池容量有限，在续航不足的时候要及时充电。电动汽车自带的家用充电桩一般是交流充电桩，室外充电场站的充电桩一般是大功率直流充电桩。
本文重点介绍充电场站使用的直流充电桩的隔离方案。纳芯微提供完整隔离电压，隔离电流检测，隔离驱动与隔离通信的解决方案，帮助客户实现更可靠的交流充电桩方案。重点介绍NIRSP31集成隔离DC-DC转换器的三通道数字隔离器方案。充电桩与充电模块通信、与不同的充电车辆都采用CAN通信的方式。由于模块输出600VDC高压，需要将CAN信号上的低压信号与充电端的电池隔开。这样不管是充电安全、还是干扰问题都能得到很好的解决。
一般的CAN通道都采用数字隔离+can收发器来实现。常规的数字隔离，需要原副变两路隔离的供电，这就使得在设计电源数的时候要专门设计一路隔离的5VDC。如下图所示：
VDD1与VDD2为两路隔离供电：
介绍使用纳芯微的NIRSP31集成隔离DC-DC转换器的三通道数字隔离器：
1、内置变压器，封装尺寸小至4mm×5mm，PCB面积减少>200%，方案成本降低>15%；
2、持1.8V~5.5V的MCU I/O电平，3.3V/5V灵活配置；
3、CMTI＞50kV/us，绝缘等级2000Vmrs，传输延时＜50ns，参数优良；
4、高EMC特性，增强的系统级ESD、EFT、以及浪涌防护能力
