Overview

The BQ27441DRZR-G1A is a single-cell lithium-ion battery fuel-gauge IC from Texas Instruments that reports state-of-charge and other battery metrics over an I2C interface. It comes in a small 12-VFDFN exposed-pad package (approx. 2.5 x 4 mm) and is specified for operation from -40 C to 85 C. TI provides software and integration support in its gauge ecosystem to help tune and deploy the part in portable products.

Why Choose This Part

Choose this part when you need a compact, single-cell fuel gauge with an I2C interface and broad temperature range. The device benefits from TI's established software and documentation for gauge tuning and integration, which can shorten bring-up time. Its small exposed-pad VFDFN package suits space-constrained portable designs.

Applications

Wearables and smartwatches
Compact fuel-gauge for single-cell Li-ion packs where small package size and low current draw matter.
Battery-powered IoT sensors
Accurate state-of-charge reporting for remote nodes that need long battery life and occasional telemetry over I2C.
Handheld instruments and scanners
Provides remaining run-time and capacity reporting to user interface and power management subsystems.
Portable medical devices
Monitors single-cell battery health and charge state for safety and maintenance scheduling.
Power banks and backup power
Fuel-gauge reporting for single-cell power packs and consumer battery products.

Getting Started

Use TI's gauge software tools and reference designs available from the TI website to configure and tune parameters for your battery chemistry and usage profile. Integration typically involves connecting the device to your system I2C bus, providing the recommended sense resistor and layout for the exposed pad, and loading the tuned parameters from TI example code or the Gauge Studio utilities.

Also Consider

MAX17048 Maxim Integrated - Low-power single-cell fuel gauge for small battery-powered devices where minimal quiescent current is critical.
BQ27441DRZR TITexas Instruments - Functionally the same BQ27441 gauge in the standard qualification/package variant for non-AEC applications or alternate sourcing.
