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.
detecting hot or cold battery packs, a power-good output (PG) indicating the presence of input power, a
TTL-level charge-enable input (CE) used to disable or enable the charge process, and a TTL-level timer and
taper-detect enable input (TTE) used to disable or enable the fast-charge timer and charge termination.

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.
