µModule Battery Chargers

Analog Devices µModule^® (micromodule) battery chargers are complete system-in-package (SiP) charging solutions with integrated dc-to-dc controllers, power transistors, input and output capacitors, compensation components, and inductors within a compact, surface-mount LGA package. Designed for use with battery chemistries requiring a constant-current/constant-voltage (CC/CV) charging method such as Li-Ion, Li-Poly, LiFePO₄, and lead acid batteries, µModule battery chargers effectively address the needs of engineers facing time and space constraints who need a highly efficient and reliable power management solution.

Buck-Boost Battery Chargers

Analog Devices manufactures a comprehensive line of high performance buck-boost battery chargers for any rechargeable battery chemistry, including lithium-Ion (Li-Ion), lead acid, and nickel-based. A buck-boost topology will accept input voltages above, below or equal to the battery voltage and charge the battery with high accuracy to its final charge voltage.

Linear Battery Chargers

Analog Devices manufactures a comprehensive line of high performance linear battery chargers for any rechargeable battery chemistry, including lithium-ion (Li-Ion), LiFePO₄, lead acid, and nickel-based. Linear battery chargers feature standalone operation and are simple to design as they do not require an external inductor.

Pulse Battery Chargers

Analog Devices manufactures a comprehensive line of high performance pulse battery chargers for any rechargeable battery chemistry, including lithium-ion (Li-Ion), lead acid, and nickel-based. Pulse chargers don't require a microcontroller/MOSFET/blocking diode, and they offer many of the benefits of switching chargers with simplicity similar to linear chargers.

SMBUS/I2C/SPI Controlled Battery Chargers

Analog Devices manufactures a comprehensive line of high performance Smart Battery Chargers for any rechargeable battery chemistry, including lithium-ion (Li-Ion), lead acid, and nickel-based. SMBus, I²C and SPI protocols are accepted. Smart battery chargers safely managing the charge and discharge states of single and multiple battery stacks and the DC input power source.

Switching Battery Chargers

Analog Devices manufactures a comprehensive line of high performance switching battery chargers for any rechargeable battery chemistry, including lithium-ion (Li-Ion), LiFePO₄, lead acid, and nickel-based chemistries. Switching battery chargers have standalone operation and feature inductor-based designs that allow high voltage and high current with high efficiency charging.
