在工程车辆中系统供电电源大多不同于普通乘用车的12V或者24V，基本采用48V的电源系统，而48V电源系统与其他的低压系统在设计时很大的一个不同点是要考虑到高压对PCB板元器件的影响，所以很多工程师在设计时会额外在信号发送和接收端加上一个光耦来做信号隔离，消除高压带给核心元器件的影响。

本文在此主要介绍国产群芯微的车规光耦 QX8801B-CUH-S在工程车油泵产品上的应用，大致应用框图如下：

在高压油泵的设计当中，一般会在MCU的CAN接口和外部的CAN收发器之间加上一个隔离光耦，而QX8801B-CUH-S高达3750V的隔离电压等级，完全满足产品的隔离需求。其次，油泵在工作时由于电机热量、油温以及MOS的发热量多个叠加导致产品内部工作环境温度会比一般的产品要高，而QX8801B-CUH-S最高工作温度能达到125℃，完全可以适应油泵产品的高温环境。最后，QX8801B-CUH-S采用的4pin SSOP4封装，满足泵类产品小型化的设计要求。

QX8801B-CUH-S主要优势特点：

1、高隔离耐压：3750Vrms；

2、工作温度范围：-40℃~+125℃；

3、SSOP4极小封装，满足产品小型化设计；

4、AEC-Q100车规认证。

综上所述，群芯微推出的车规光耦QX8801B-CUH-S非常适合用于工程车油泵产品。

【应用】国产驱动光耦QX3120助力光储逆变器IGBT驱动设计，高达2.5A驱动能力

针对逆变器的设计，离不开IGBT/MOS这类全控型的功率半导体器件，首先在驱动设计时必须考虑到隔离，为了保证控制器安全可靠的工作，在设计IGBT驱动时需要通过一款隔离驱动芯片来对控制单元发出的驱动信号进行隔离保护。本文重点介绍关于国产群芯微的栅极驱动光耦QX3120助力光储逆变器驱动设计。
