Product Summary

The BQ27500DRZR-V120 system-side Li-Ion battery fuel gauge is a microcontroller peripheral. It provides fuel gauging for single-cell Li-lon battery packs. The BQ27500DRZR-V120 requires little system microcontroller firmware development. The BQ27500DRZR-V120 resides on the system’s main board and manages an embedded battery (non-removable) or a removable battery pack. The applications of the BQ27500DRZR-V120 include Smartphones, PDAs, Digital Still and Video Cameras, Handheld Terminals, MP3 or Multimedia Players.
