Integrated circuits for power management are known as power management integrated circuits (power management ICs, PMICs, or PMUs as a unit).
Although the term “PMIC” can apply to a wide variety of chips (or modules in system-on-a-chip devices), the majority of them contain several DC/DC converters or their control components.
The global PMICs for automotive camera module market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
The new PMICs from ROHM for camera modules in next-generation vehicles comply with the functional safety requirements of ISO 26262.
Automotive camera modules, which are increasingly being used in Advanced Driver Assistance Systems, can now be equipped with PMICs that are ISO 26262 and ASIL-B compatible, designated as BD868xxMUF-C (BD868C0MUF-C, BD868D0MUF-C), according to a recent announcement from ROHM Semiconductor (ADAS).
There are now more onboard cameras due to ADAS’s ongoing development in recent years. A serious accident could result from even one camera failing, so it is crucial that manufacturers of cars and vehicle components, including semiconductor suppliers, adhere to the international safety standard ISO 26262.
At the same time, introducing the idea of functional safety is becoming more important.
Renesas introduces a new PMIC for camera systems in automobiles. A highly integrated Power Management IC called IISL78083 was recently released by Renesas Electronics Corporation (PMIC).
The power supply design for a number of HD camera modules is made simpler by this new IC. It shortens the length of development cycles and lowers bill of materials (BOM) expenses and supply chain hazards.
The automobile camera PMIC is capable of handling output currents of up to 750mA per output and accepts direct-from-battery (36-42V) or power-over-coax (15-18V) supply sources.
This power level provides enough headroom for currently available image sensors with a resolution of up to seven megapixels, as well as for future sensors with even higher resolution.
A primary high-voltage synchronous buck regulator, two secondary low-voltage synchronous buck regulators, and a low-dropout (LDO) voltage regulator are all included in the feature-rich 4-channel ISL78083 automotive camera PMIC.
By using seven to ten fewer external components than competitive products, the ISL78083 reduces BOM costs.
The ISL78083 additionally has three power-good indicators, a reset output/fault indicator, four over-voltage (OV) and four under-voltage (UV) monitors. It provides a second reference for the OV/UV monitors.
