Introducing the BQ24074RGTR/BQ24074RGTT Battery Charger IC from Texas Instruments

The BQ24074RGTR and BQ24074RGTT are highly integrated lithium-ion battery chargers and power-path management devices from Texas Instruments, crafted for portability and efficiency. These advanced power management chips are designed to cater to a wide range of applications, particularly those requiring single-cell lithium-ion or lithium-polymer battery charging, such as smartphones, tablets, and other portable electronics.

Key Features

• High Integration: The BQ24074 series offers a complete charging solution with integrated power FETs, current sensing, and reverse-blocking protection, reducing the need for external components and simplifying the design process.
• Flexible Power Management: With an input voltage range of 4.35V to 10V, these devices can accommodate various power sources, including USB ports and wall adapters.
• Programmable Charging Parameters: Designers can set the charge current, pre-charge current, termination current, and charge voltage to match specific battery requirements, ensuring optimal charging for different battery chemistries and capacities.
• Thermal Regulation: To ensure safety and maintain longevity of the battery, the BQ24074 series incorporates a thermal regulation feature that reduces charge current during high-temperature conditions.
• Power-Path Management: The ICs allow the system to be powered from the adapter while simultaneously charging the battery, ensuring uninterrupted operation even when the battery is low or absent.
• Status Indicators: Integrated status outputs provide real-time charge status, which can be used to drive LEDs or interface with a host processor for charge monitoring.

Package Options and Part Numbers

The BQ24074 series is available in two package options:

• The BQ24074RGTR is offered in a 16-pin QFN package, providing a compact footprint for space-constrained applications.
• The BQ24074RGTT variant comes in a 16-pin TSSOP package, which is ideal for designs with more relaxed space requirements.

Both versions are engineered with the same precision and quality that Texas Instruments is known for, ensuring reliable and efficient battery management for your next portable project. Incorporating the BQ24074RGTR or BQ24074RGTT into your design will significantly enhance battery performance, extend battery life, and provide robust safety features, all while simplifying the overall design process.
