Product Summary

The LTC 4160/LTC4160-1 are high efficiency power man- ? agement and Li-Ion/Polymer battery charger ICs. They each include a bidirectional switching PowerPath? controller with automatic load prioritization, a battery charger, and an ideal diode. The LTC4160/LTC4160-1’s bidirectional switching regulator transfers nearly all of the power available from the USB port to the load with minimal loss and heat which eases thermal constraints in small spaces. These devices feature a precision input current limit for USB compatibility and Bat-Track output control for efficient charging. In addition, the ICs can also generate 5V at 500mA for USB On-The- Go applications
