These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam  
during storage or handling to prevent electrostatic damage to the MOS gates.  
DESCRIPTION (CONTINUED)  
The battery is charged in three phases: conditioning, constant current, and constant voltage. In all charge  
phases, an internal control loop monitors the IC junction temperature and reduces the charge current if the  
internal temperature threshold is exceeded.  
The charger power stage and charge current sense functions are fully integrated. The charger function has  
high-accuracy current and voltage regulation loops, charge status display, and charge termination. The input  
current limit and charge current are programmable using external resistors.

(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings  
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating  
conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. All voltage  
values are with respect to the network ground terminal unless otherwise noted.
