PMIC for Automotive Camera
BD86852MUF-C
用于摄像头的PMIC(电源管理IC)“BD86852MUF-C”可以为各主要制造商的CMOS图像传感器的电源系统提供更好的管理功能。由于仅通过单个IC即可进行电压设置和时序控制,因此可将安装面积减少约41%,从而有助于车载摄像头模块实现小型化。另外,由于电路结构可将集中在摄像头用PMIC上的热量分散开,因此通过抑制发热量,实现了78.6%的高转换效率,有助于进一步降低功耗。

OVERVIEW
BD86852MUF-C is a power management IC with primary buck converter (DC/DC1), secondary buck converters (DC/DC2 and DC/DC3), external linear regulator control block and the power-on reset function for CMOS sensor and image sensing power supply. Output voltage and sequence are selectable and applicable to various image sensor power supply. This device adopts small package VQFN24FV4040 which is optimal for camera module. In addition, this device has a pin that can be programmed to turn on/off the spread spectrum providing a lower noise regulated outputs.
