RTQ2081C-QF 是一款专为车用雷达应用设计的电源管理 IC。其内建三组降压转换器、一组高电源抑制比低压降稳压器及一组通用型低压降稳压器。高电压降压转换器支援最高 24V 输入电压范围，并可承受最高 36V 的 Load Dump 事件，因此可直接连接至 12V 车用电池。RTQ2081C-QF 为各通道整合过压与欠压监测电路、错误输出指示功能及透过 I²C 介面的故障状态回报功能，以提升系统功能安全性。此外，装置内建看门狗计时器（WDT），并支援可设定的上限与下限视窗容差，以增强系统监控能力及应用弹性。透过 I²C 或出厂预设设定，还可实现多项可程式化功能，包括各通道输出电压调整、自订电源启动时序、过压（OV）及欠压（UV）监测门槛设定，以及看门狗逾时时间配置。RTQ2081C-QF 采用具可焊侧边的 WET-WQFN 4mm × 4mm 24-pin 封装。建议接面温度范围为 -40°C 至 150°C，环境温度范围为 -40°C 至 125°C。
