BQ27426 Product details

Description

The Texas Instruments BQ27426 battery fuel gauge is a single-cell gauge that requires minimal userconfiguration and system microcontroller firmware development, leading to quick system bring-up.

Features

Single-cell Li-ion battery fuel gauge.
Resides on system board.
Supports embedded or removable batteries.
Powers directly from the battery with integrated LDO.
Supports a low-value external sense resistor (10 mΩ).
Ultra low 9 μA operating current when the load is below 10 mA, set by Sleep Current threshold.
Battery fuel gauging based on patented Impedance Track™ technology.
Provides three selectable preprogrammed profiles.
