ROHM recently announced the AEC-Q100 qualified 2.8W output Class AB monaural speaker amplifiers the BD783xxEFJ-M series (BD78306EFJ-M, BD78310EFJ-M and BD78326EFJ-M) ideal for instrument clusters - used in vehicles equipped with autonomous driving and ADAS.

ROHM developed the BD783xxEFJ-M series for vehicle clusters requiring various sound outputs at high volume, including warning sounds, turn signals, welcome tones, and voice guidance. Also, adopting a new type of over current protection (OCP) circuit provides protection against output shorts (damage due to accidental terminal contact) that was difficult to achieve in the past, making it possible to deliver high 2.8W output. Thermal shutdown and under voltage lock out (UVLO) are also built in to ensure high reliability protection against abnormal conditions (more info).
