FEATURES
LTC4098 USB Compatible Switching Power Manager/Li-Ion Charger with Overvoltage Protection DESCRIPTIO
The LTC®4098 is a high efficiency USB PowerPathTM controller and full-featured Li-Ion/Polymer battery charger.

It seamlessly manages power distribution from multiple sources including USB, wall adapter, automotive, firewire or other high voltage DC/DC converters, and a Li-Ion/Polymer battery. The LTC4098's internal switching regulator automatically limits its input current for USB compatibility. For automotive and other high voltage applications, the LTC4098 interfaces with a Linear Technology external switching regulator to provide a high efficiency high voltage power path. Both the USB and the optional high voltage inputs feature Bat-Track optimized charging to provide maximum power to the application and ease thermal issues in high power density applications with input supplies from 5V to as high as 38V. An overvoltage circuit protects the LTC4098 from high voltage damage
