CAMERA MODULE/ECU for ADAS Products


UCR

SOP

Broad lineup supports a wide range of needs for greater miniaturization, larger currents, multiple outputs,


hybrid configurations, and more


Following on the heels of legislation enacted in the US approving the use of cameras to improve vehicle and driver safety,


the number of camera-equipped vehicles has risen dramatically. However, mounting cameras on vehicles without sacrific-


ing design poses several challenges, requiring that the camera module and PMIC be as small as possible and the number


of external components kept to a minimum. Information on surrounding objects is obtained by the camera module,


millimeter-wave radar, or other source and processed by the camera ECU, which then transmits signals and commands to


other ECUs for controlling the steering and brakes to improve driver safety. Power supplies for the high-performance MCUs


(or DSPs) used in camera ECUs require large current-handling capability, high efficiency, reduced voltage operation, and


other key characteristics. ROHM offers an extensive lineup of high-voltage/secondary LDOs and switching regulators


compatible with direct battery connection as well as system power supplies (PMICs) optimized for camera ECUs.
