New PMICs for camera modules in next-gen vehicles

30-06-2022 | ROHM Semiconductor | Automotive Technologies

ROHM now offers the ISO 26262 and ASIL-B compliant PMICs, BD868xxMUF-C (BD868C0MUF-C, BD868D0MUF-C), for automotive camera modules that are increasingly being adopted in ADAS.

As part of the ComfySIL series, these ICs are 'FS (Functional safety) process compliant' products (the highest grade), indicating compliance with the ISO 26262 standard.

Satisfying the strict conditions for functional safety permits these latest products to enable safety design in next-generation vehicles equipped with ADAS. Moreover, the four power supply systems (three DC-DC and one LDO) required for automotive cameras are integrated into a 3.5mm × 3.5mm package, delivering the industry's smallest size in comparable camera PMICs. They are furnished with an anomaly status notification mechanism such as abnormal voltage detection and feedback through I2C. This decreases the number of components by three compared to former solutions, resulting in a 25% smaller mounting area than conventional solutions and contributing to smaller vehicle cameras. At the same time, a broad range of output voltage and sequence control settings can be configured to satisfy the varying demands of CMOS image sensors from different manufacturers, simplifying development considerably.
