DESCRIPTION
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
restarts the charge if the battery voltage falls below
an internal threshold. The bqTINY™ automatically
enters sleep mode when V
CC
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 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.
