BQ2092 具有 4 个 LED 驱动器的多化合物符合 SBS 0.95 的电量监测

BQ2092 描述

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 NiCd, NiMH, and Li-Ion battery chemistries.

The bq2092 uses the SMBus protocol that supports many of the Smart Battery Data (SBData) commands. The bq2092 also supports SBData charge control. Battery state-of-charge, capacity remaining, remaining time and chemistry are available over the serial link. Battery-charge state can be directly indicated using a four-segment LED display to graphically depict battery full-to-empty in 25% increments.

The bq2092 estimates battery self-discharge based on an internal timer and temperature sensor and user-programmable rate information stored in external EEPROM
