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 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 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.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

(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 DC and with respect to VSS.

(1) Pins VCC and IN must be tied together.
(2) If Vin is between UVLO and 4.35V, and above the battery voltage, then the IC is active (can deliver some charge to the battery), but the
IC will have limited or degraded performance (some functions may not meet data sheet specifications). The battery may be
undercharged (VO(reg) less than in the specification), but will not be overcharged (VO(reg) will not exceed specification).
