Product Features
- An integrated battery fuel gauge IC designed for multi-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 monitoring.
- Integrates a high-accuracy battery State-of-Charge (SoC) estimation system.
- Incorporates 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 battery learning process that requires full charge and full discharge cycles.
- 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 historical battery usage data.
- Programmable low-battery indication output pin.
- Provides 96 bytes of embedded Flash memory.
