ISL78083 Automotive Camera Power Management IC

Renesas’ PMIC provides an extensive feature set and power density to fit inside ever-shrinking HD camera modules

Image of Renesas' ISL78083 Automotive Camera Power Management ICRenesas’ ISL78083 automotive camera power management IC (PMIC) is a versatile multi-rail power IC comprised of a primary high-voltage synchronous buck regulator, two secondary low voltage synchronous buck regulators, and a low dropout (LDO) regulator. The ISL78083 offers four overvoltage and undervoltage monitors, three power-good indicators, and a reset output/fault indicator. To limit common-cause failures, this PMIC also includes a second reference for the overvoltage (OV)/ undervoltage (UV) monitors, independent from the reference of the regulators.

The ISL78083 is intended for high-density power applications requiring few external components and minimal board space. It offers an extensive feature set configured using an internal one-time programmable (OTP) memory. Nearly all device options, such as each output voltage selection, power sequencing, and OV/UV thresholds, are internally configured and require no external components for selection. The regulators also offer internal compensation. The bucks are synchronous to achieve high efficiency and are capable of operating in harsh environments requiring high ambient temperature. The ISL78083 is available in a 4 mm x 4 mm 24 Ld step-cut QFN (SCQFN) package with an exposed pad for improved thermal performance. It is AEC-Q100 qualified to Grade 1 and operates across an ambient temperature range of -40°C to +125°C and is electrically specified across a junction temperature range of -40°C to +150°C.
