The is a high efficiency USB PowerPath Controller and full-featured LiFePO4 Battery Charger for use with high reliability handhelds. The LTC4098-3.6 charge algorithm is optimized for LiFePO4 by implementing a 1-hour float voltage termination timer and a 0 to 60°C NTC-based charge qualification range. Furthermore, completely discharged batteries are charged at the full programmed charge current. The LTC4098-3.6"s switching regulator can automatically limit its input current for USB compatibility. For automotive and other high voltage applications, the LTC4098‑3.6 interfaces with an external switching regulator. Both the USB input and the auxiliary input controller feature Bat-Track optimized charging to provide maximum power to the application and reduced heat in high power density applications with input supplies from 5V to as high as 38V.
