Overview
Meeting the strict requirements for functional safety allows the BD868xxMUF-C to facilitate safety design in next-generation vehicles equipped with ADAS. Moreover, the 4 power supply systems (3 DC/DC + 1 LDO) necessary for automotive cameras are integrated into a 3.5mm × 3.5mm package, achieve the industry's smallest size in comparable camera PMICs. They are equipped with an anomaly status notification mechanism such as abnormal voltage detection and feedback via I2C. This reduces the number of components by 3 compared to former solutions, which results into a 25% smaller mounting area compared to conventional solutions and contributes to smaller vehicle cameras. (The above 25% is just an example, further miniaturization is possible by optimizing for individual applications.) At the same time, a wide range of output voltage and sequence control settings can be configured to meet the varying requirements of CMOS image sensors from different manufacturers, simplifying development considerably.
Application Examples
- Rear view/perimeter cameras, drive recorders, driver monitoring systems, etc.
