Renesas Electronics ISL78083 Automotive Camera Power Management IC
Renesas Electronics ISL78083 Automotive Camera Power Management IC is a versatile multi-rail power IC. It features a primary high-voltage synchronous buck regulator, two secondary low-voltage synchronous buck regulators, and an LDO regulator. It also offers four overvoltage and undervoltage monitors, three power-good indicators, and a reset output/fault indicator. To limit common-cause failures, the ISL78083 also includes a second reference for the OV/UV monitors, independent from the regulators' reference.
Features
