Product Summary
The BQ2060A is a SBS-Compliant Gas Gauge IC for battery pack or in-system installation maintains an accurate record of available charge in rechargeable batteries. The BQ2060A monitor capacity and other critical battery parameters for NiCd, NiMH, Li-Ion, and lead-acid chemistries. The BQ2060A uses a V-to-F converter with automatic offset error correction for charge and discharge counting. For voltage, temperature, and current reporting, the device uses an A-to-D converter. The onboard ADC also monitors individual cell voltages in a Li-Ion battery pack and allows the BQ2060A to generate control signals that may be used in conjunction with a pack supervisor to enhance pack safety.
