Analog Devices, Inc. (ADI) has introduced the LT8491 buck-boost battery charging controller that features Maximum Power Point Tracking (MPPT), temperature compensation and I
2C interface for telemetry and control.
The device operates from input voltages above, below or equal to the regulated battery float voltage. The LT8491 offers three selectable Constant Current Constant Voltage (CC-CV) charging profiles, making it ideal for charging a variety of battery chemistry types including sealed lead acid, gel and flooded cells, and Li-Ion. All charge termination algorithms are provided onboard, eliminating the need for software or firmware and thus reducing design cycle time.
