STMicroelectronics' AEK-AUD-C1D9031 is a very compact AVAS solution based on the SPC582B60E1 Chorus family MCU and FDA903D Class D audio amplifiers that emit warning sounds to alert pedestrians of the presence of e-vehicles.

The AEK-AUD-C1D9031 integrates two audio amplifiers in stereo mode or two separate audio channels. The board's compact size allows the designer to strategically place different modules around the vehicle to ensure that warning sounds can be heard along the entire vehicle length. All the modules can be controlled by a central MCU via CAN interface.
