BD86852MUF-C
PMIC for Automotive Camera
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.
