The LTC®4071 is an easy-to-use, tiny shunt battery system for Li-Ion/Polymer batteries, which integrates a charger and battery pack protection in one IC. The LTC4071, with its 550nA operating current, charges and protects batteries at up to 50mA from previously unusable very low current, intermittent or continuous charging sources. A near zero current (<0.1nA) low battery latching disconnect function protects even low capacity batteries from deep discharge and potentially irreparable damage. Housed in a low profile (0.75mm) 8-lead 2mm × 3mm DFN package, the LTC4071 provides the only complete and ultracompact battery charger and protection solution operating with low level power sources such as energy scavenging/ harvesting, resistive isolation or solar-powered systems. It can charge Li-Ion/Polymer, coin cell and thin film batteries.
