Frequently Asked Questions
What is the state-of-charge accuracy of the BQ27441DRZT-G1A?
The BQ27441DRZT-G1A achieves up to ±1% state-of-charge (SOC) accuracy using Texas Instruments' Impedance Track algorithm, which continuously monitors battery impedance and adapts to cell aging without requiring a host processor to run gauge calculations.
Does the BQ27441DRZT-G1A require an external sense resistor?
No. The BQ27441DRZT-G1A integrates an internal sense resistor and ships with a default LiCoO2 battery chemistry profile pre-loaded, so it can operate in many designs without any external sense resistor or custom chemistry programming, simplifying BOM and PCB layout.
What package does the BQ27441DRZT-G1A use and what are its dimensions?
The BQ27441DRZT-G1A comes in a 12-pin DRZT SON (Small Outline No-lead) package. This compact leadless package is suitable for space-constrained portable and wearable applications and offers excellent thermal performance compared to leaded alternatives.
Which communication interface does the BQ27441DRZT-G1A use?
The BQ27441DRZT-G1A communicates via a standard I2C interface, allowing a host microcontroller to read battery parameters such as remaining capacity, full charge capacity, average current, temperature, and voltage with minimal pin count.
What are common applications for the BQ27441DRZT-G1A?
Typical applications include smartphones, tablets, wearables, portable medical devices, handheld industrial equipment, and IoT sensor nodes — any product powered by a single-cell Li-ion or Li-polymer battery that requires accurate fuel gauging with low power consumption.
