DESCRIPTION
The bqTINYC0116 series are highly integrated Li-Ion and
Li-Pol linear charge management devices targeted at
space limited portable applications. The bqTINYC0116
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 bqTINYC0116 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 bqTINYC0116 automatically
re-starts the charge if the battery voltage falls below an
internal threshold. The bqTINYC0116 automatically enters
sleep mode when V
CC
supply is removed.
In addition to the standard features, different versions
of the bqTINYC0116 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.
