Product Summary

The Texas Instruments BQ27510DRZT system-side Li-Ion battery fuel gauge is a microcontroller peripheral that provides fuel gauging for single-cell Li-Ion battery packs. The BQ27510DRZT requires little system microcontroller firmware development. The BQ27510DRZT resides on the system’s main board and manages an embedded battery (non-removable) or a removable battery pack. The BQ27510DRZT 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 BQ27510DRZT requires only PACK+ (P+), PACK– (P–), and Thermistor (T) connections to a removable battery pack or embedded battery. Applications include Smartphones, PDAs, Digital Still and Video Cameras, Handheld Terminals and MP3 or Multimedia Players.
