RT9514
Linear Single Cell Li-Ion Battery Charger IC
General Description
The RT9514 is a fully integrated low cost single-cell Li-
Ion battery charger IC ideal for portable applications. The
RT9514 is capable of being powered up from AC adapter.
The RT9514 enters sleep mode when AC adapter is
removed.
The RT9514 optimizes the charging task by using a control
algorithm including preconditioning mode, fast charge
mode and constant voltage mode. The charging task is
terminated as the charge current drops below the preset
threshold. The AC adapter charge current can be
programmed up to 1A with an external resister. The internal
thermal feedback circuitry regulates the die temperature
to optimize the charge rate for all ambient temperatures.
The RT9514 features 18V maximum rating voltages for
AC adapter. The other features are under voltage
protection, over voltage protection for AC adapter supply.

Note 1. Stresses listed as the above “Absolute Maximum Ratings” may cause permanent damage to the device. These are for
stress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended
periods may remain possibility to affect device reliability.
Note 2. θJA is measured in the natural convection at TA = 25°C on a high effective thermal conductivity test board (4 layers,
2S2P) of JEDEC 51-7 thermal measurement standard. The case point of θJC is on the expose pad for the package.
Note 3. Devices are ESD sensitive. Handling precaution is recommended.
Note 4. The device is not guaranteed to function outside its operating conditions.
