Analog Devices’ integrated battery monitor ICs provide high accuracy measurements for precise voltage determination. ADI’s battery fuel gauges accurately measure and report battery capacity in single cell or multicell handheld applications, with uncompromised charge accuracy thanks to a variety of unique sensing techniques that appear seamless to the user. Some models also provide battery voltage and temperature, while others integrate a sense resistor to minimize component count and increase accuracy even further.

Analog Devices offers multifunctional power management integrated circuits (PMICs) that combine advanced battery charging capabilities with multiple system rails, all within a compact form factor. These highly integrated multifunction battery chargers simplify design, reduce PCB space, and lower BOM costs while enabling seamless power management across input sources like wall adapters, USB ports, and lithium batteries. Featuring PowerPath control, high efficiency switch-mode power management, and precise thermal regulation, our PMICs ensure optimal battery charging and power flow, with support for high charge currents and accurate float voltage for portable applications.

Analog Devices’ USB charging and management products utilize key battery charging features and include a PowerPath circuit topology that enables managed power flow, allowing a load to be powered from both VIN and the battery. Our USB charging products offer shorter charging times, instant-on operation (even with a dead battery), and more flexibility for the device designer. Both linear charging for simplicity, and switch mode for higher charging efficiency topologies are offered. Other key features of the USB power family include standalone operation with onboard charge termination, high voltage operation, and thermal regulation.
