Product InformationFeatures
Impedance Track, bqEASY are trademarks of Texas Instruments. Description
The Texas Instruments bq27501 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 bq27501 resids on the system main board, and manages an embedded batery (non-removable) or a removable battery pack. The device uses the patented impedance Track algoritm for fuel gauging, and provides information such as remaiing battery capacity (mAh), state-of-charge (%), run-time to empty (min.), battery voltage (mV), and temperature (°C). The device works with identification resistors in battery packs to gauge batteries of different funamental chemistries and/or different rated capacities. |
