DESCRIPTION
The bqTINYt series are highly integrated Li-Ion and
Li-Pol linear charge management devices targeted at
space limited portable applications. The bqTINYt
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 bqTINYt 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 bqTINYt automatically
re-starts the charge if the battery voltage falls below an
internal threshold. The bqTINYt automatically enters
sleep mode when V
CC
supply is removed.
In addition to the standard features, different versions
of the bqTINYt 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 valid input power; a
TTL−level 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.
