These ICs are ‘FS (Functional safety) process compliant’ products (the highest grade), indicating compliance with the ISO 26262 standard.
Meeting the requirements for functional safety allows these latest products 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.
Further miniaturisation 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.
In addition to the four models (BD868A0MUF-C, BD868B0MUF-C, BD868C0MUF-C, BD868D0MUF-C) that comply with both ISO 26262 and ASIL-B, the lineup will include the non-ISO 26262-compliant BD868C1MUF-C for users that do not require ASIL compliance. Also, ROHM can offer the products based on customer setup requirements like output voltages, voltage tolerances, sequencing and functional safety requirements.
