Li-Ion battery fuel gauge is a microcontroller•
Microcontroller Peripheral Provides:peripheral that provides fuel gauging for single-cell
– Accurate Battery Fuel Gauging Li-Ion battery packs. The device requires little system
– Internal Temperature Sensor for System microcontroller firmware development. The
Temperature Reporting bq27500/01 resides on the system main board, and
– Battery Low Interrupt Warning managesan embedded battery (non-removable)ora
– Battery Insertion Indicator removable battery pack.
– BatteryID Detection 96 Bytesof Non-Volatile Scratch-Pad The bq27500/01 uses the patented Impedance
FLASH Track™ algorithm for fuel gauging, and provides
information such as remaining battery capacity•
Battery Fuel Gauge Based on Patented(mAh), (%), run-timeto empty (min.),
Impedance Track™ Technologybattery voltage (mV), and temperature (°C).
– Models the Battery Discharge Curve for
Accurate Time-to-Empty Predictions Battery fuel gauging with the bq27500 requires only
– Automatically Adjusts for Battery Aging, PACK+ (P+), PACK– (P–), and Thermistor (T)
Battery Self-Discharge, and connections to a removable battery pack or
