bq27501: Works With Battery ID Resistor in  
Battery Pack  
The Texas Instruments bq27500/01 system-side  
Li-Ion battery fuel gauge is  
peripheral that provides fuel gauging for single-cell  
Li-Ion battery packs. The device requires little system  
microcontroller  
bq27500/01 resides on the system main board, and  
manages an embedded battery (non-removable) or a  
removable battery pack.

The bq27500/01 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).  
•
Battery Fuel Gauge Based on Patented  
Impedance Track™ Technology  
–
Models the Battery Discharge Curve for  
Accurate Time-to-Empty Predictions  
Battery fuel gauging with the bq27500 requires only  
PACK+ (P+), PACK– (P–), and Thermistor (T)  
connections to  
embedded battery. The bq27501 works with  
identification resistors in battery packs to gauge  
batteries of different fundamental chemistries and/or  
significantly different rated capacities.
