The bqTINY_ series are highly integrated Li-Ion and Li-Pol linear charge management devices targeted at space
limited portable applications. The bqTINY_ series offer integrated powerFET and current sensor,reverse blocking
protection, high accuracy current and voltage regulation, charge status, and charge termination, in a small
package.The bqTINY_ charges the battery in three phases: conditioning, constant current, and constant voltage.
Charge is terminated based on minimum current. An internal charge timer provides a backup safety feature for
charge termination. The bqTINY_ automatically re-starts the charge if the battery voltage falls below an internal
threshold. The bqTINY_ automatically enters sleep mode when VCC supply is removed.
In addition to the standard features, different versions of the bqTINY_ 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
¨
Clevel charge-enable input (CE) used to disable or enable the charge process;
and a TTL-level timer and termination enable (TTE) input used to disable or enable the fast-charge timer and
charge termination.
