PCA9452是一款单芯片AEC Q100 2级汽车电源管理IC(PMIC)，专为支持汽车应用中的i.MX93x系列处理器而设计。

该器件提供6个高效降压稳压器、5 个LDO、1个400mA负载开关、2通道电平转换器和32.768KHz晶振驱动器。3个降压稳压器支持动态电压调节(DVS)功能以及可编程的上升和下降时间，这些降压稳压器支持远程感测以补偿降压稳压器负载的IR压降。该器件的工作环境温度范围为-40°C至105°C。

六个降压稳压器用于为i.MX93x应用处理器和DRAM存储器供电。 LDO1静态电流超低，可为安全非易失性存储器(SNVS)供电，因为当输入电压有效时，该LDO始终处于"ON(开启)"状态。

PCA9452集成了逻辑转换器，是一种具有自动方向感测功能的2位双电源转换收发器。它支持双向电压电平转换，可以用作I2C的电平转换器。400mA负载开关为具有内置放电电阻的SD卡提供3.3V电源。
