Abstract	An on-line control IC for watch stepping motors that allows significant power savings is presented. This system enables the open loop control of a wide range of motors. This leads to a significantly longer battery life, enables to cut motor production costs and to increase system reliability. Particularly, the COCA IC offers an extreme adaptability to the different motor types that can be driven, thanks to a programmable correlation function, and performs an immediate missed-step recognition and recovery.
