AnalogicTech Announces Highest Power Density 2A Battery Charger

Advanced Analogic Technologies Incorporated unveiled its high power density linear battery charger for Lithium-ion/polymer batteries, the AAT3697. The charger is housed in a 3mm x 3mm TDFN package, and offers 2A of charge current. The new battery charger includes two status monitor output pins capable of driving external LEDs to indicate charge status. One also comes across a battery charge timer and the device automatically shuts down in case of voltage or over-temperature.

"Power density is an increasingly important consideration in a wide variety of high performance handheld systems, like smart phones, GPS systems and portable media players that use high capacity batteries," notes Bill Weiss, product line director for AnalogicTech. "This new linear charger offers the industry's highest charge-current-to-solution-footprint ratio while the integration of AnalogicTech's intelligent digital thermal loop feature enables the host system to use a high current linear charger without the risk of pulse charging the battery."
