RT9536

Linear Single Cell Li-Ion Battery Charger IC for Portable

Applications

General Description

Features

^28V Maximum Rating for DC Adapter

The RT9536 is a fully integrated single cell Li-ion battery

charger IC ideal for portable applications. The RT9536

^Internal Integrated Power MOSFETs

optimizes the charging task by using a control algorithm

^Support 4.2V or 4.35V/2.3A Factory Mode

including pre-charge mode, fast charge mode and constant

^50mA Low Dropout Voltage Regulator

voltage mode. The input voltage range of the VIN pin can

^Status Pin Indicator

be as high as 28V. When the input voltage exceeds

^Programmed Charging Current

the OVP threshold, it will turn off the charging MOSFET

^Under Voltage Lockout

to avoid overheating of the chip.

^Over Voltage Protection

^Thermal Feedback Optimized Charge Rate

^RoHS Compliant and Halogen Free

In RT9536, the maximum charging current can be

programmed with an external resistor. For USB application,

the user can set the current to 100mA/500mA through

the EN/SET pin. For the factory mode, the RT9536 can

allow 4.2V or 4.35V/2.3A power pass through to support

system operation. It also provides a 50mA LDO to support

the power of peripheral circuit. The internal thermal

feedback circuit regulates the die temperature to optimize

the charge rate for all ambient temperatures. The RT9536

provides protection functions such as under voltage

protection, over voltage protection for VIN supply and

thermal protection for battery temperature.

Applications

 Cellular Phones

 Digital Cameras

 PDAs and Smart Phones

 Portable Instruments
