Battery Management

This Product Selection Guide contains information to help select products in the Battery Management category on DigiKey.com

Products in the Battery Management PMIC (Power Management Integrated Circuit) family are used for battery-related monitoring and control functions including authentication, cell balancing, condition monitoring, fuel gauging, source selection, short circuit protection, over- and under-voltage protection, and others. Note that while some products in this family may include a battery charging function among their features, products implementing a charging function as a principle feature are classified separately.


SelectionCharacteristics

Function: Indicates the primary functionality of the device and what its purpose in the circuit is.

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.

Fault Protection: Enumerates protection features incorporated by a device and/or operational hazards against which a device is protected in some manner.

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.
