1. Description
The LTC®4099 is an I²C controlled high efficiency USB PowerPath™ controller and full-featured Li-Ion/Polymer battery charger. It seamlesslymanages power distribution from multiple sources including USB, a wall adapter and a Li-Ion/Polymer battery. The LTC4099EUDC#PBF automatically limits its input current for USB compatibility. For automotive and other high voltage applications, the LTC4099 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. The I²C port allows digital control of important application parameters including input current limit, charge current and float voltage. Several status bits can also be read back via I²C. An overvoltage protection circuit guards the LTC4099 fromhigh voltage damage on the lowvoltage VBUS pin.The LTC4099 is available in a 20-Lead 3mm × 4mm × 0.75mm QFN Package.
