Product Summary
The BQ27200DRKR is a single cell li-ion and li-pol battery gas gauge IC. This IC monitor a voltage drop across a small current sense resistor connected in series with the battery to determine charge and discharge activity of the battery. Compensations of the BQ27200DRKR for battery temperature, self-discharge, and discharge rate are applied to the capacity measurments to provide available time-to-empty in-formation across a wide range of operating conditions. The applications of the BQ27200DRKR include: PDA, Smart Phones, MP3 Players, Digital Cameras, Internet Appliances, Handheld Devices.
