The LTC4160/LTC4160-1 are high efficiency power management 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.

An overvoltage circuit protects the LTC4160/LTC4160-1 from high voltage damage on the USB/wall adapter inputs with an external N-channel MOSFET and a resistor.

The LTC4160/LTC4160-1 are available in a 3mm × 4mm × 0.75mm QFN surface mount package.
