ams AS3442 and AS3447 - Power and Communication Interfaces are charging and communication accessories for smart earbuds and Bluetooth earpieces. These power and communication interfaces enable battery charging of up to 150mA and communication to earpiece simultaneously. The AS3442 and AS3447 interface devices include a Microcontroller Unit (MCU) inside the charger cradle that can request data from the earphone while the charging process is on-going and vice versa. These interfaces enable data exchange between cradle and accessory, increases design flexibility, reduce the number of mechanical connection, and also offer accessory firmware updates.
