【经验】AEC-Q100车规认证多通道信号隔离芯片SI8660适用于变速箱
目前新能源汽车中涉及到变速箱控制系统会用到多颗传感器检测齿轮的状态，通过对信号的检测实现实现系统的变速调节；出于防止对信号的干扰及系统的可靠性考虑，会在检测到的信号与主控芯片MCU之间加隔离芯片进行隔离，在隔离的选择在考虑绝缘耐压等问题同时，还需要小封装，满足产品小体积要求等功能；SILICON LABS的隔离芯片SI8660，具有6个独立的隔离通道，相比其它方式的单通道隔离具有减小布板体积的优势，另外SI8660过了AEC-Q100的车规认证，工作温度满足-40℃-125℃范围，隔离电压达5KV，可以满足芯片在系统中的可靠性要求。
图1为SI8660做为新能源汽车中涉及到变速箱的控制系统示意图，变速箱上的传感器对齿轮进行检测，将信号传递到控制器MCU，通过MCU进行指令下发，实现对新能源汽车速度的控制，其中SI8660起到在控制系统与执行系统之间的隔离，可以满足信号传递低延时，高速效应的需求，另外高达5KV的电压，实现原副边可靠绝缘；通过AEC-Q100的车规认证，满足新能源汽车对芯片车规要求；
图1 SI8660运用在变速箱系统的框图
SI8660相比其他的隔离芯片用来做变速箱控制系统信号隔离优势如下：
1. 采用容隔离技术，具有高达50KV/us的CMTI,抗芯片的两个地之间的信噪比更好，提升了芯片抗干扰能力及提升系统的可靠性；
2. SI8660高达150Mbps的通讯速率，可支持不同信号通讯速率的需求；
3. SI8660原副边信号的通讯延时时间低至10ns，提高系统的响应速度；
4. 芯片支持5KV的隔离电压，宽的工作温度-40℃-125℃，符合AEC-Q100汽车级认证；芯片本身具有高可靠性，可以提升系统的可靠性；
芯片的原副边具有宽的工作电压范围为2.5V-5.5V,在设计上建议靠近芯片的VDD和GND之间加0.1uF和10uF电容并联来加强电压的稳定性，防止由于VDD过压造成芯片损坏；

【应用】低成本电容驱动隔离芯片SI8660/SI8261，助力1kW伺服驱动器
传统1kW伺服驱动器逆变部分IPM隔离采用6颗单通道的光耦来实现，制动部分采用1颗驱动光耦来驱动制动IGBT单管，通常会遇到光耦成本过高的问题，本方案通过采用Silicon Labs推出的低成本的电容隔离驱动芯片SI8660/SI8261，不仅可以解决上述问题，同时可降低产品整体设计成本。

在设计小功率伺服驱动器时，功率器件使用IPM模块，同时在MCU控制电路和IPM驱动管脚之间希望使用隔离芯片实现隔离功能，同时要求体积尽可能小，请帮忙推荐相应产 品？
小功率伺服驱动器使用IPM模块，其自带驱动功能，外围电路仅需设计MCU和IPM管脚之间的隔离，推荐使用Silicon Labs的Si8660数字隔离芯片，其集成6路数字 隔离，传输速率可达150Mbps，绝缘耐压最高达到5000kVrms。
