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.

Select power transformers by input frequency, secondary VA, rectifier load, isolation, regulation and inrush. Build a clearer specification for your next RFQ.
