Power & Communication Interface

The POW:COM interface enables concurrent battery charging at up to 150mA and data exchange between a charger cradle, an earpiece and a mobile phone. The interface needs only two pins per device, giving design flexibility and improving the reliability of charging operations. By implementing the POW:COM interface in earbuds, manufacturers can improve the user experience, giving enhanced communication capabilities and convenient charging. Furthermore, no bluetooth component is required in the charging cradle.
