背景
近年来,随着ADAS技术的发展,每辆汽车所安装的车载摄像头数量也在增加。同时,由于车载摄像头的故障可能会导致严重的事故,因此引入有助于预防事故的“功能安全”理念变得越来越重要。不仅汽车和汽车电子产品制造商,就连半导体等高精度电子元器件制造商也需要满足国际功能安全标准“ISO 26262”的要求。
ROHM早在2018年就通过德国第三方认证机构T?V Rheinland获得了ISO 26262的开发流程认证。此外于2021年,ROHM还推出了“ComfySIL?”品牌,旨在通过“功能安全”的产品为用户和系统的安全、安心与舒适做出贡献。BD868xxMUF-C在“ComfySIL?”品牌中,也是符合ISO 26262流程的,而且属于满足其最高等级“FS process compliant”的产品,有助于提高下一代汽车的安全性。
概要
BD868xxMUF-C能够满足严格的功能安全要求,使配备ADAS的下一代汽车所需的安全设计更加容易。此外,在仅为3.5mm×3.5mm的封装中,还内置有车载摄像头所需的4个电源系统(DC/DC:3个系统,LDO:1个系统),并配备了异常状态通知机构,可以检测到电压异常等状况并通过I2C来反馈。在同类PMIC中,实现了业界超小尺寸。与以往产品相比,可减少3个元器件,安装面积可缩减25%,有助于车载摄像头的小型化。此外,还可以进行更宽范围的输出电压设置和时序控制设置,可满足各制造商不同CMOS图像传感器的不同要求,有助于减少开发工时。
