"Renesas Electronics Group (TSE: 6723), a global semiconductor solution provider, announced to provide a new power and functional safety solution for systems based on r-car V3H system on chip (SOC) for advanced driving assistance systems (ADAS) such as front camera and driver monitoring camera.
The new solution includes a 42V Synchronous Step-Down pre regulator raa271050, which can connect the 12V power supply voltage of the vehicle and step it down to an intermediate voltage of 3.3V or 5V. At the same time, the seven channel PMIC (power management IC) raa271000 can reduce the output of raa271050 to various power supply voltage values required by r-car V3H and its peripheral devices (such as lpddr4 memory). Both products comply with iso-26262 standard and can support system security up to ASIL level D. The solution meets all power and functional safety requirements of r-car V3H, provides power supply voltage and current capacity, and meets all power specification requirements, including sequence, voltage accuracy and load step response. At the same time, all necessary power supply and digital monitoring functions shall be provided to ensure safety.
Renesas's new solution has excellent efficiency, and the power loss can be reduced by 33% compared with other pmics under the same working conditions. Lower power consumption allows products to operate at higher temperatures, reducing cooling costs and delivering superior reliability. In addition, both raa271050 and raa271000 meet the design requirements of r-car, which can reduce the PCB area and reduce the device cost. The reference hardware solution provided by Renesas includes new components, which reduces customers' design time and test requirements.
Niall Lyne, vice president of analog power supply and video business division of Renesas electronic automobile, said: "the new power supply and functional safety solutions show our expertise in the field of power design and can save a lot of costs for customers adopting r-car V3H. At the same time, it provides a complete and tested reference design to help developers implement the latest ADAS camera application quickly and efficiently.
Key features of r-car V3H power solution
Integrated 12 bit SAR ADC with up to 16 external inputs, which can monitor internal and external signals without adding system ADC
Dynamic voltage frequency regulation (dvfs) adjusts the output voltage to minimize power consumption
Optional spread spectrum clock to reduce EMI
Built in support of r-car V3H SOC activation, simplifying SOC self-test program
Complete ADAS camera solution
The complete ADAS front camera solution includes raa271050 and raa27100, eaglecam camera module of LUPA Electronics GmbH, and Renesas r-car V3H and r-car v3m system on chip (SOC). The "successful portfolio" is an open turnkey solution that provides flexible, high-performance perception while reducing time to market and bill of materials (BOM) costs.
