R2A20057BM

Lithium-Ion Battery Switching Charger IC with Auto Load Current Distribution

R03DS0069EJ0050

Rev.0.50

Dec 10, 2012

This is a target specification. Some specs are subject to change.

Description

R2A20057BM is a semiconductor integrated circuit designed for Lithium-ion battery charger control IC.

Built-in Input current limitation circuit compliant with USB requirements and dual output (system and battery)

control circuit allows to supply the system power and the battery charging power simultaneously from input

power.

Features

- Allows to USB charging

- Automatic DPDM detection and automatic input current limitation setup

(USB battery charging 1.2 and VBUS divided port)

- Input current limitation is programmable

I²C 100mA/500mA/1000mA/1500mA/2100mA/Limitless/Suspend

External control signal (CTL and USUP) 100mA/500mA/Suspend

- Weak battery charge function

- High precision charge control voltage : 4.2V+/-21mV (+/-0.5%),4.35V+/-22mV (+/-0.5%)

- Auto load current distribution control

- Auto power management between system load and battery charge within input current limitation

- Built-in low Ron path switch (30mohm)

- System output voltage Switching regulation:battery voltage + 0.3V

- Compliance with JEITA guideline

- Thermistor I/F detects battery temp. to control CC/CV parameters by built-in charge profile

- I2C interface

- Adjustable charging parameters

- Protection function

- Input UVLO/OVLO

- Battery over voltage detection

- Timer

- Chip temperature detection - Thermal shutdown

- Recharge function

- Gate control for system Load SW (/SG)

- Input power OK output (/POK)

- Charge status output (/STAT)

Application

- Digital Still Camera

- Digital Video Camera

- Mobile Phone

- PDA/PND

- Tablet/Note PC

- Portable Audio Player

- Portable Game Machine
