System-Side Impedance Track(TM) Fuel Gauge

The Texas Instruments BQ27500 01 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 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 gauging with the BQ27500 requires only PACK+ (P+), PACK? (P?), and Thermistor (T) connections to a removable battery pack or embedded battery. The bq27501 works with identification resistors in battery packs to gauge batteries of different fundamental chemistries and/or significantly different rated capacities.
