Linear Single Cell Li-Ion Battery Charger IC

General Description

Features

^z18V Maximum Rating for AC Adapter

^zInternal Integrate P-MOSFETs

^zAC Adapter Power Good Status Indicator

^zCharge Status Indicator

The RT9505 is a fully integrated low cost single-cell Li-

Ion battery charger IC ideal for portable applications. The

RT9505 is capable of being powered up fromAC adapter.

The RT9505 enters sleep mode when AC adapter is

removed.

^zUnder Voltage Protection

^zOver Voltage Protection

The RT9505 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 1Awith an external resister. The internal

thermal feedback circuitry regulates the die temperature

to optimize the charge rate for all ambient temperatures.

^zAutomatic Recharge Feature

^zBattery Temperature Monitoring

^zSmall 10-Lead WDFN Package

^zThermal Feedback Optimizing Charge Rate

^zRoHS Compliant and 100% Lead (Pb)-Free

Applications

z Digital Cameras

The RT9505 features 18V maximum rating voltages for

AC adapter. The other features are under voltage

protection, over voltage protection forAC adapter supply

and battery temperature monitoring.

z Cellular Phones

z Personal Data Assistants (PDAs)

z MP3 Players

z Hand Held PCs
