Product Features

  • An integrated battery fuel gauge IC designed for 1-cell to 3-cell lithium battery packs.
    • Integrates dual 16-bit ADCs for accurate measurement of battery voltage, current, and temperature.
    • Supports low-cost current sensing resistors and provides automatic calibration functionality.
    • Features both an internal temperature sensor and external temperature sensing inputs for precise temperature measurement.
  • Integrates a high-accuracy battery State-of-Charge (SoC) estimation system.
    • Employs the proprietary GaugePack™ algorithm, which combines Coulomb Counting, Open-Circuit Voltage (OCV) estimation, and cell characteristic profile-based fuel gauging techniques.
    • Provides automatic compensation for load conditions, temperature variations, battery aging, and self-discharge effects.
    • Eliminates the conventional learning cycle requiring full charge and full discharge operations.
    • Automatically updates battery information and stores it in Flash memory.
  • Programmable voltage, current, and temperature protection modes and protection thresholds.
  • Programmable low-battery warning thresholds.
  • Automatically backs up battery usage history data.
  • Programmable low-battery indication output pin.
  • Provides 96 bytes of embedded Flash memory.
  • Features programmable battery capacity indication.
  • Supports 3-LED or 4-LED battery capacity indication.
  • Supports multiple power management modes.
  • Can be powered directly from battery cells.
  • Supports a 2-wire communication interface.
