General Description
The bq2092 Gas Gauge IC With SMBus-Like Interface is intended for battery-pack or in-system installation to maintain an accurate record of available battery charge. The bq2092 directly supports capacity monitoring for Ni Cd, Ni MH, and Li-Ion battery chemistries.
The bq2092 uses the SMBus protocol that supports many of the Smart Battery Data (SBData) mands. The bq2092 also supports SBData charge control. Battery state-ofcharge, capacity remaining, remaining time and...
