Product Summary

The BQ27541DRZR is a single cell Li-Ion battery fuel gauge that provides fuel gauging for single-cell Li-Ion battery packs. The device requires little system microcontroller firmware development for accurate battery fuel gauging. The BQ27541DRZR resides within the battery pack or on the system’s main-board with an embedded battery (nonremovable). The BQ27541DRZR 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 (℃). The applications of the BQ27541DRZR include Smartphones, PDAs, Digital Still and Video Cameras, Handheld Terminals, MP3 or Multimedia Players.
