Overview

Description

The bq34110PW is a Texas Instruments standalone lithium‑ion/Li‑polymer battery gas gauge designed for single‑cell packs. It provides accurate state of charge (SoC) and remaining capacity estimation, using a model‑based estimation that combines coulomb counting with cell impedance/voltage/temperature data. It supports calibration/learning to adapt to aging and temperature, and reports SoC, state of health (SoH) proxies, and fault/status information to the host.
Key features (high level)
- SoC, remaining capacity, and health estimation with loss/aging compensation
- Coulomb counting plus voltage, current, and temperature sensing
- Host communication via SMBus/I2C; multiple addressing options
- Low quiescent current; suitable for compact battery packs
- Small PW package variant
Typical applications
- Mobile devices, wearables, IoT sensors, and other single‑cell battery packs
Notes
- For exact pinout, electrical specs, and integration guidelines, refer to the bq34110PW datasheet and TI resources.
