RT9503A

Fully Integrated Linear Single Cell Li-Ion Battery Charger

with Power Path

General Description

Features

^zAutomatic Input Supplies Selection

^z18V Maximum Rating for AC Adapter

^zIntegrated Selectable 100mA and 500mA USB

Charge Current

The RT9503A is a fully integrated low cost single-cell Li-

Ion battery charger IC ideal for portable applications. The

RT9503Ais capable of being powered up via theAC adapter

and USB (Universal Serial Bus) port inputs. The RT9503A

can automatically detect and select the AC adapter and

the USB port as the power source for the charger. The

RT9503A enters sleep mode when both supplies are

removed.

^zInternal Integrated Power MOSFETs

^zAC Adapter Power Good Status Indicator

^zCharge Status Indicator

^zExternal Capacitor Programmable Safety Timer

^zUnder Voltage Protection

The RT9503A 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 USB charge current can be selected

from preset ratings of 100mA and 500mA, while the AC

adapter charge current can be programmed up to 1Awith

an external resistor. The internal thermal feedback circuitry

regulates the die temperature to optimize the charge rate

for all ambient temperatures.

^zOver Voltage Protection

^zAutomatic Recharge Feature

z Battery Temperature Monitoring

z Small 16-Lead WQFN Package

z Thermal Feedback Optimizing Charge Rate

z Power Path Controller

z RoHS Compliant and Halogen Free

Applications

z Digital Cameras

The RT9503A features 18V and 7V maximum rating

voltages forAC adapter and USB port inputs respectively.

Other features include external programmable safety timer,

under voltage protection, over voltage protection for AC

adapter supply, battery temperature monitoring, power

supply status indicators and charge status indicator.

z Cellular Phones

z PDAs , Smart Phones and MP3 Players
