Battery Charger PMICs (Power Management Integrated Circuits) are a family of component-level products used to implement battery charge control and charge management functions in electronic devices. Classified primarily by the battery chemistry and number of cells with which a device is designed for use, these devices provide current or voltage regulation and monitoring functions necessary for safe recharging of electrochemical cells and supercapacitors.
