Overview

Description

BQ2060A-E619DBQR is a Texas Instruments single‑cell Li‑ion battery fuel gauge IC. It monitors pack voltage, current (via a sense resistor), and temperature to estimate state of charge (SOC) and remaining capacity using coulomb counting with voltage/temperature data. It provides an SMBus/I2C‑compatible serial interface for a host microcontroller to read SOC, capacity, voltage, current, temperature, and gauge status, and to configure parameters such as design capacity and alert thresholds. External components required include a current sense resistor and a temperature sensor (thermistor). Typical use is in portable devices with a single-cell battery to improve battery life estimation and safe operation. The suffix -E619DBQR denotes a specific packaging/lot/version variant in TI’s catalog (packaging, date/lot code); refer to the datasheet for exact electrical specs, package type, and supported features for this variant.
