BQ24161BRGET

Battery Chargers Overview

The BQ24161BRGET is a single-cell switchmode lithium-ion battery charger IC manufactured by Texas Instruments. It supports input voltages up to 10V and delivers a maximum programmable charging current of 2.5A. The device utilizes an I2C interface for configuration and monitoring. It operates within a temperature range of -40°C to +85°C and is housed in a 24-VQFN (4x4) package with an exposed pad.

Battery Chargers Feature Summary

• Integrates power path management for system load prioritization during input presence
• Supports I2C digital interface for precise control and status reporting
• Includes JEITA-compliant battery temperature monitoring via thermistor pin
• Features integrated protection against overvoltage and overtemperature conditions

Battery Chargers Applications

• Single-cell lithium-ion or lithium-polymer battery charging systems
• Portable consumer electronics requiring compact power management solutions
• Industrial devices operating in extended temperature environments
• USB-powered applications with power path management requirements

Battery Chargers Procurement Notes

Verify the specific suffix BRGET corresponds to the required tape-and-reel packaging quantity when ordering. Confirm that the 24-VQFN footprint matches the target PCB layout, particularly regarding the exposed thermal pad dimensions. Ensure compatibility with the intended I2C address configuration before finalizing procurement specifications.

Battery Chargers Selection Notes

Select this component for designs requiring a single-cell Li-Ion/Polymer solution with integrated FETs and power path management. It is suitable for applications needing high efficiency and digital control via I2C. Consider the 2.5A maximum current limit and 10V input voltage ceiling when defining system power requirements. Evaluate the 24-VQFN package constraints for thermal dissipation needs.
