    BQ27426YZFR

    The Texas Instruments BQ27426 battery fuel gauge
    is a single-cell gauge that requires minimal userconfiguration and system microcontroller firmware
    development, leading to quick system bring-up.
    Three chemistry profiles are preprogrammed to
    enable minimum user-configuration, and to help
    manage customer inventory across projects with
    different battery chemistries. The BQ27426 battery
    fuel gauge has very low sleep power consumption
    leading to longer battery run time. Configurable
    interrupts help save system power and free up the
    host from continuous polling. Accurate temperature
    sensing is supported via an external thermistor.
    The BQ27426 battery fuel gauge uses the patented
    Impedance Track™ algorithm for fuel gauging, and
    provides information such as remaining battery
    capacity (mAh), state-of-charge (%), and battery
    voltage (mV).
    Battery fuel gauging with the BQ27426 fuel gauge
    requires connections only to PACK+ (P+) and PACK–
    (P–) for a removable battery pack or embedded
    battery circuit. The tiny, 9-ball, 1.62 mm × 1.58
    mm, 0.5 mm pitch NanoFree™ chip scale package
    (DSBGA) is ideal for space-constrained applications.

      SPECIFICATION

      • Single-cell Li-ion battery fuel gauge
      – Resides on system board
      – Supports embedded or removable batteries
      – Powers directly from the battery with integrated
      LDO
      – Supports a low-value external sense resistor
      (10 mΩ)
      • Ultra low 9 μA operating current when the load is
      below 10 mA, set by Sleep Current threshold.
      • Battery fuel gauging based on patented
      Impedance Track™ technology
      – Provides three selectable preprogrammed
      profiles for 4.2-V, 4.35-V, and 4.4-V cells
      – Reports remaining capacity and state-of-charge
      (SOC) with smoothing filter
      – Adjusts automatically for battery aging, selfdischarge, temperature, and rate changes
      – Estimates battery state-of-health (aging)
      • Microcontroller peripheral interface supports:
      – 400-kHz I2C serial interface
      – Configurable SOC interrupt or
      battery low digital output warning
      – Internal temperature sensor or host reported
      temperature or external thermistor
