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 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 pre-charge
current and termination current threshold are programmed via an external resistor. The fast charge current value
is also programmable via an external resistor.

(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.
