This Product Selection Guide contains information to help select products in the Battery Chargers category on DigiKey.com
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.
SelectionCharacteristics
Battery Chemistry: Indicates the chemical system(s) of batteries or cells for which a device is designed to be compatible.
Number of Cells: Indicates the quantity of cells of the specified size or type that are accommodated by a product.
Current - Charging: Describes mode(s) of charge delivery.
Programmable Features: Indicates charge cycle parameters that are user-configurable for a given device.
Fault Protection: Enumerates protection features incorporated by a device and/or operational hazards against which a device is protected in some manner.
Charge Current - Max: Indicates the rated maximum output current of a device.
Battery Pack Voltage: The nominal or maximum voltage of the battery packs with which a device is suitable for use.
Voltage - Supply (Max): Typically represented by a range, this indicates the low and high voltage limits which one can expect standard operation. Voltages outside this range may damage the device and other system components.
Interface: Indication of which interface(s) or protocol(s) are used by the device to communicate with other components in the system.
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
Mounting Type: Indicates how the device is attached.
Package / Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the supplier device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.
Supplier Device Package: This is what the manufacturer calls the package of this device. They are manufacturer specific. It is typically best to use the actual dimensions from the datasheets rather than to go by this terminology when designing your circuit.
