36 V APPLICATIONS • Cellular Phones • PDAs • MP3 Players • Digital Cameras • Internet Appliances 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 g...
