- Reference Design - REF66012
- PMIC solution for ADAS SoC Reference Design
The intelligent front camera(IFC) integrates a 2 million pixels high-definition camera and supports access to multiple millimeter wave radars, which can implement L2 level forward ADAS function. This solution uses the Horizon Journey2 chip with 4TOPS AI computing power and the Infineon TRAVEO II series CYT4BF microcontroller. By deploying corresponding visual algorithms on Horizon Journey2 to identify obstacles, lane lines, and other traffic elements, and using the Infineon TRAVEO II series CYT4BF microcontroller for vehicle sensor fusion and vehicle control, this solution can achieve ADAS functions such as AEB, ACC, LCC, and TJA. By selecting Rohm PMIC chips with ASIL D functional safety level, such as BD96801Q09 and BD9S303MUF, the reliability and stability of the intelligent front camera(IFC) can be ensured.
