RT9528

I²C Programmable Linear Single Cell Li-Ion Battery Charger

with Auto Power-Path Management and USB/AV Switch

General Description

Features

^z28V Maximum Rating for AC Adapter

^zAuto Power Path Management (APPM)

^zHigh-Speed USB Operation

The RT9528 is a programmable single-cell Li-ion battery

charger with I²C programmable control I/F, Auto Power-

Path Management IC and USB/AV Switch. For the

RT9528, there is no need to use external MOSFET. The

RT9528 enters sleep mode when supplies are removed.

The RT9528 optimizes the charging task by using a control

algorithm including pre-charge mode, fast charge mode

and constant voltage mode. The RT9528 includes

termination, timer, charge current and V_SYSsettings via a

serial I²C control I/F.

^zUSB/Audio/Video Switches

^zNegative Rail Audio Signal Path

^zI²C controlled Interface

^zIntegrated 3.3V LDO for TS Circuitry

^zIntegrated Power MOSFETs

^zInterrupt Status Indicator

^zPower Good and Charge Status Indicators

^zUnder/Over Voltage Protection

z Thermal Feedback Optimizing Charge Rate

z 28-Lead WQFN Package

The RT9528 provides protections for the battery pack,

charger and input circuitry such as over current, under

voltage, over voltage, thermal regulation and thermal

protection. Status can be monitored via the serial port for

charge state and fault conditions.

z RoHS Compliant and Halogen Free

Applications

z Digital Cameras

The internal thermal feedback circuitry regulates the die

temperature to optimize the charge rate for all ambient

temperatures.

z PDAs and Smart Phones

z Portable Instruments
