【应用】日清纺耐高压、低电流LDO R1516x用于车载总线数据记录仪，满足AEC-Q100标准
随着车载控制系统越来越复杂，CAN总线数据量越来越大。在车辆前期调试及验证阶段，总线数据具有的参考分析作用越来越大。根据此趋势，近日，某客户近期参与设计一款车载总线数据记录仪。
此款车载总线数据记录仪主要功能：记录存储车辆行驶过程中CAN总线数据到SD卡中，便于后期分析优化车辆控制状态，同时记录偶发性异常故障。车辆ON有效时，进入数据记录状态，熄火后进入待机状态。
初期设计时主要考虑的是功能的实现，软硬件的结构设计。输入电压为车载蓄电池，电压12.0V，经电源芯片稳压输出5.0V。供给主要器件MCU及SD卡读写芯片、CAN收发器使用。
当ON有效时，CAN总线数据开始发送。这时通过CAN收发芯片唤醒MCU。系统进入工作状态，MCU通过CAN收发芯片读取总线数据，并通过USART与SD卡专用管理芯片通讯记录数据到SD卡中。
当车辆进入熄火状态，CAN总线数据停止收发，MCU进入待机模式。系统结构如下图所示。
功能实现后，发现装车后车辆处于熄火状态时，系统进入待机模式，MCU及其他电路处于待机状态时耗电<200μA；但是前级电源采用的是国产普通的LDO，静态功耗较高，前级总耗电高达8mA，无法满足待机状态低功耗的要求。
通过电源选型手册及世强平台推荐，选用了NISSHINBO日清纺（原理光微电子）的R1516x-5.0V。R1516x满足AEC-Q100标准，符合汽车级产品标准，其主要参数如下图所示。
R1516x是Nisshinbo推出的一款基于CMOS工艺的耐高压、低电流稳压器。该系列产品内含反馈保护电路、热保护电路，特别是在异常情况下，可以有效保护后级电路。工作温度范围为–40℃～+105℃，最大输入电压为36V，满足车载电压波动大，温度变化大特点。输出电压范围为1.8V~6.2V，根据本项目实际情况选用5.0V输出电压。R1516x有两种封装，小尺寸可选SOT-89-5，超高功率可选HSOP-6J。根据PCB上元件放置的位置选用HSOP-6J封装。
根据数据手册，参考相关电路设计电源部分原理图如下所示。
根据实际使用环境和电气特点。在电源前级加入了电源防反接，浪涌防护、ESD保护等电路。
根据R1516X的特点，前级加入100μF滤波电容和0.1μF的去耦电容。后级加入0.1μF的去耦电容和10μF的滤波电容。
经过PCB设计和元件采购、焊接、调试顺利完成。优化后根据实际硬件电路分别测试工作状态和待机状态电流：当车辆ON信号激活有效后，R1516x-5.0V平均输入电流24.2mA，待机模式总输入电流0.6mA。
车辆供电电压在9-16V之间波动时，输出电压在4.99-5.01V之间波动。输出精度完全满足系统工作需求。
经项目组硬件评审后一致认为R1516x性能卓越，特别是在负载小电流、高精度、低静态功耗方面，完全满足客户大部分车载硬件的电源芯片要求。在后期产品更新换代时本着集中采购，减少物料种类和库存的原则，适当更换此电源芯片。
