The BQ2060A-E619DBQG4 is a multi-chemistry SBS v1.1 compliant Gas Gauge with 5 LED drivers. It monitors capacity and other critical battery parameters for NiCd, NiMH, Li-ion and lead-acid chemistries. The BQ2060A uses a voltage-to-frequency converter with automatic offset error correction for charge and discharge counting. For voltage, temperature and current reporting, It uses an A-to-D converter. The on board ADC also monitors individual cell voltages in a Li-ion battery pack and allows the gauge to generate control signals that may be used with a pack supervisor to enhance pack safety. It supports the smart battery data (SBData) commands and charge-control functions. It communicates data using the system management bus (SMBus) 2-wire protocol or the Benchmarq 1-wire HDQ16 protocol. The data available include the remaining battery capacity, temperature, voltage, current and remaining run-time predictions.
