DESCRIPTION (CONTINUED)
In addition to the standard features, different versions of the bqTINY-II offer a multitude of additional features. These include
temperature sensing input for detecting hot or cold battery packs; power good (PG) output 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 (TTE) input used to disable or enable the fast-charge timer and charge termination.
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 MOSFET gates.

(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.
(2) All voltages are with respect to VSS.
