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.

Parametrics

BQ2060A absolute maximum ratings: (1)VCC—Supply voltage Relative to VSS: -0.3 to +6.0 V; (2)VIN–All other pins Relative to VSS: -0.3 to +6.0 V; (3)TOPR Operating temperature: -20 to +70 ℃.

Features

BQ2060A features: (1)Provides accurate measurement of available charge in NiCd, NiMH, Li-Ion, and lead-acid batteries; (2)Supports SBS Smart Battery Data Specification v1.1; (3)Supports the 2-wire SMBus v1.1 interface with PEC or 1-wire HDQ16; (4)Reports individual cell voltages; (5)Monitors and provides control to charge and discharge FETs in Li-Ion protection circuit; (6)Provides 15-bit resolution for voltage, temperature, and current measurements; (7)Measures charge flow using a V-to-F converter with offset of less than 16μV after calibration; (8)Consumes less than 0.5mW operating; (9)Drives a 4- or 5-segment LED display for remaining capacity indication; (10)28-pin 150-mil SSOP.
