BQ2052 锂原电池电量监测计，具有高速 1 线 (HDQ) 接口、3 种可编程 LED 模式

BQ2052 描述

The bq2052 Lithium Primary Gas Gauge IC is intended for battery-pack or in system installation to maintain an accurate record of available battery capacity. The IC monitors a voltage drop across a sense resistor connected in series with the cells to determine discharge activity of the battery. The bq2052 applies compensations for battery temperature and discharge rate to the available charge counter to provide available capacity information across a wide range of operating conditions.

Compensated available capacity may be directly indicated using an LED display. The LED display is programmable and can be configured as two, four, or five segments. These segments are used to depict available battery capacity
