MAX8934 LiIon battery char­ger

Using MAX8934 LiIon battery char­ger can be designed a simple battery charger which monitors the battery temperature (TBATT) while charging, and automatically adjusts the fast-charge current and charge termination voltage as the battery temperature varies.
The MAX8934 LiIon battery char­ger can monitor the battery temperature while the battery is discharging, and provides a warning flag (OT) to the system in the event that the battery is over temperature. The MAX8934 operates with either separate inputs for USB and AC adapter power .
The MAX8934 battery charger can operate over an input voltage range of 4.1-6.6 volts for both , DC and USB power supply .
Charge current limit and DC current limit can be set up to 1.5A and 2A respectively, while USB input current can be set to 100mA or 500mA
