1.3 DESCRIPTION
– Accurate Battery Fuel Gauging
– Internal Temperature Sensor for System
The Texas Instruments bq27500 system-side Li-Ion
Temperature Reporting
battery fuel gauge is a microcontroller peripheral that
– Battery Low Interrupt Warning
provides fuel gauging for single-cell Li-Ion battery
– Battery Insertion Indicator
packs. The device requires little system
– 96 Bytes of Non-Volatile Scratch-Pad FLASH
microcontroller firmware development. The bq27500
• Battery Fuel Gauge Based on Patented
resides on the system main board and manages an
Impedance Track™ Technology
embedded battery (non-removable) or a removable
– Models the Battery Discharge Curve for
battery pack.
Accurate Time-to-Empty Predictions
The bq27500 uses the patented Impedance Track
– Automatically Adjusts for Battery Aging,
algorithm for fuel gauging, and provides information
Battery Self-Discharge, and
such as remaining battery capacity (mAh),
Temperature/Rate Inefficiencies
state-of-charge (%), run-time to empty (min.), battery
– Low-Value Sense Resistor (10 mΩ or Less)
voltage (mV), and temperature (°C).
