The ISL78083 simplifies power supply design for use in multiple HD camera modules, reducing development cycles, bill of materials (BOM) cost and supply chain risks. The automotive camera PMIC accepts direct-from-battery (36-42V) or power-over-coax (15-18V) supply sources and supports output currents up to 750mA per output. This power level offers ample headroom for existing image sensors up to 7-megapixel and future sensors with even higher resolution.
Niall Lyne, Senior Director, Automotive Business Unit at Renesas, said, “The innovative ISL78083 PMIC expands Renesas’ support for automotive surround view camera systems beyond the image processing capabilities of the R-Car SoC and into the design of the HD satellite cameras. Cameras designed with the ISL78083 are smaller and can be conveniently mounted in vehicle locations that provide the desired surround view camera angles without negatively impacting style or aerodynamics.”
The 4-channel ISL78083 automotive camera PMIC includes a primary high-voltage synchronous buck regulator, two secondary low-voltage synchronous buck regulators, and a low-dropout (LDO) voltage regulator.
It also includes integrated feedback and integrated compensation, as well as minimising BOM cost as it requires 7-10 less external components compared to competing solutions. The ISL78083 also features four overvoltage (OV) and four undervoltage (UV) monitors, three power-good indicators and a reset output/fault indicator. A second reference is supplied for the OV/UV monitors.
Mass production quantities of the ISL78083 automotive camera PMIC are available now in a 4mm x 4mm, 24-lead SCQFN wettable flank package.
