Smart Phones  
PDAs  
• Resides on System Main Board  
Digital Still and Video Cameras  
Handheld Terminals  
MP3 or Multimedia Players  
– Works With Embedded or Removable  
Battery Packs  
• Uses PACK+, PACK–, and T Battery Terminals  
• Microcontroller Peripheral Provides:  
– Accurate Battery Fuel Gauging  
1.3 DESCRIPTION  
– Internal Temperature Sensor for System  
Temperature Reporting  
– Battery Low Interrupt Warning  
– Battery Insertion Indicator  
– 96 Bytes of Non-Volatile Scratch-Pad FLASH  
The Texas Instruments bq27500 system-side Li-Ion  
battery fuel gauge is a microcontroller peripheral that  
provides fuel gauging for single-cell Li-Ion battery  
packs.  
The  
device  
requires  
little  
system  
microcontroller firmware development. The bq27500  
resides on the system main board and manages an  
embedded battery (non-removable) or a removable  
battery pack.  
• Battery Fuel Gauge Based on Patented  
Impedance Track™ Technology  
– Models the Battery Discharge Curve for  
Accurate Time-to-Empty Predictions  
The bq27500 uses the patented Impedance Track  
algorithm for fuel gauging, and provides information  
such as remaining battery capacity (mAh),  
state-of-charge (%), run-time to empty (min.), battery  
voltage (mV), and temperature (°C).  
– Automatically Adjusts for Battery Aging,  
Battery Self-Discharge, and  
Temperature/Rate Inefficiencies  
– Low-Value Sense Resistor (10 mΩ or Less)  
• I2C™ Interface for Connection to System  
Microcontroller Port  
Battery fuel gauging with the bq27500 requires only  
PACK+ (P+), PACK– (P–), and Thermistor (T)  
• 12-Pin 2,5-mm × 4-mm SON Package  
connections to  
a
removable battery pack or  
embedded battery.
