Analog Devices offers a broad portfolio of battery charger IC devices for any rechargeable battery chemistry, including Li-Ion, LiFePO₄, lead acid, and nickel-based, for both wired and wireless applications. These high performance battery charging devices are offered in linear or switching topologies and are completely autonomous in operation.

Our battery charger ICs offer many standard features for battery management and safety, including on-chip battery pre-conditioning, current limiting, temperature-controlled charging, monitoring and protection, telemetry via SMBus or I²C interface, and support for high voltage, multiple-cell and multi-chemistry batteries with a single device.

ADI’s battery chargers support wide range of applications such as lithium ion battery monitoring, PV cell energy harvesting, industrial monitoring, wearable devices, and other portable equipment.

Analog Devices offers a broad portfolio of high performance battery management IC devices including battery chargers, companion battery charge controllers, and battery backup managers. Battery chargers are for both wireless and wired applications and may be used for any rechargeable battery chemistry. Companion battery charger controllers are used in conjunction with virtually any internally compensated switching regulator to form a complete battery charging solution. Battery backup managers enable battery charging and backup power from the battery to the system output in the event of a system power removal or outage. Explore our battery management IC products and wide range of applications.

Hot swap products from Analog Devices perform all the housekeeping functions necessary to hot swap plug-in boards. These parts also integrate with industry-leading converter and amplifier cores for power monitoring and control with patented circuitry delivering unmatched ±0.3% monitoring accuracy. These devices safely and accurately monitor the power usage in a typical server rack system, which enables operators to remotely monitor each rack individually thus saving energy and minimizing system downtimes.

Analog Devices has a very broad line of LED driver ICs for automotive, display backlighting, handheld, and general high-power lighting applications. They are configured as either inductorless (charge pump) or switching regulator-based LED drivers that support driving white LEDs in series, parallel or combination. Topologies include boost regulator, buck regulator, buck/boost, SEPIC topology LED drivers, and more. Regardless of topology, these ICs offer the highest efficiency, lowest noise, and the smallest footprints. Other features of our portfolio include integrated Schottky diodes, accurate LED current matching, and multiple output capability.

Analog Devices’ power over Ethernet (PoE) products encompass a wide variety of power sourcing equipment (PSE) and powered device (PD) controllers that support multiple power levels: IEEE PoE (13W, 802.3af), IEEE PoE+ (25.5W, 802.3at), IEEE PoE++ (71.3W, 802.3bt), and ADI LTPoE++ (90W) standard. Our PSE and PD controllers provide complete PoE solutions and use external components such as power MOSFETs and sense resistors to lower resistance in the power path—minimizing heat dissipation and maximizing power efficiency. In addition, our robust cable discharge protection scheme, a high abs max rating on all analog pins, wide operating temperature, and overtemperature protection all make for extremely rugged PoE solutions that meet IEC61000 cable discharge requirements that far exceed ESD and cable ESD testing levels.

Analog Devices offers a wide range of switching regulators that operate in step up (boost), step down (buck), and inverting modes. These devices are capable of generating a fixed or adjustable output voltage, and offer up to 2 A of output current. Some of the features available in ADI’s portfolio of switching regulators are low battery detector, user adjustable current limit, a variety of switching frequencies, and a reduced number of external components. This highly integrated, versatile family of products is intended to minimize external components for space challenged applications.
