Renesas Electronics simplifies the design of the power supply for the panoramic camera system in the car

     Renesas Electronics, a leading global supplier of semiconductor solutions, announced the introduction of a new, highly integrated power management IC (PMIC), ISL78083, which simplifies power design for multiple HD camera modules to reduce development cycles, BOM costs and supply chain risk. The on-board camera PMIC can support battery-powered directly (36-42V) or coaxially powered (15-18V) power supply and supports output current of up to 750mA per output; This power level provides ample room for existing image sensors (up to 7 megapixels) and future higher-resolution sensors.

     "The new ISL78083 PMIC extends Renesas' support for in-vehicle panoramic camera systems, not only enhancing the image processing capabilities of the R-Car SoC, but also extending its application to the design of high-definition satellite cameras," said Niall Lyne, senior director of Renesas' Electronic Automotive Division. The ISL78083 camera allows for a smaller size, which makes it easier to mount on the vehicle and provide panoramic views without compromising vehicle design or aerodynamics."

     The ISL78083 Automotive Camera PMIC is feature-rich with 4 channels, including a main high voltage synchronous buck regulator, two auxiliary low voltage synchronous buck regulators and a low voltage difference (LDO) voltage regulator. With integrated feedback and integrated compensation, only output inductors and capacitors are needed for efficient power configuration. The ISL78083 minimizes BOM costs, requiring 7-10 fewer external components than competing solutions. The ISL78083 also features four overvoltage (OV) and four undervoltage (UV) monitors, as well as three power good status indicators and reset output/failure indicators, providing a backup reference for the OV/UV monitor.
