BQ24298RTWT

Battery Chargers Overview

The BQ24298RTWT is a single-cell USB switch IC and charger from Texas Instruments, designed for portable applications. It operates within a supply voltage range of 3.9 V to 6.2 V and supports a maximum output current of 3 A. The device utilizes an I2C control interface for configuration and monitoring. It is housed in a WQFN-24 package suitable for surface mount technology. The component functions as both a charge management unit and a USB switch, enabling power path management for lithium-ion or lithium-polymer batteries.

Battery Chargers Feature Summary

• Integrates USB switch functionality with single-cell battery charging capabilities
• Supports I2C digital interface for precise control and system monitoring
• Features power path management to optimize system power distribution

Battery Chargers Applications

• Portable consumer electronics requiring integrated USB charging and switching
• Smartphones and tablets utilizing single-cell lithium-based batteries
• Wearable devices with strict space and power efficiency constraints

Battery Chargers Procurement Notes

Verify the specific ordering suffix RTWT against the manufacturer's official datasheet to confirm the tape and reel packaging configuration. Ensure compatibility with I2C bus voltage levels and check humidity sensitivity classification prior to assembly. Confirm that the WQFN-24 thermal pad requirements align with the target PCB design for adequate heat dissipation during high-current operation.

Battery Chargers Selection Notes

Select this component when a combined USB switch and charger solution is required for single-cell systems. It is appropriate for designs needing I2C programmability rather than fixed RC-set parameters. Consider the 3 A output limit and 6.2 V input ceiling to ensure they meet the specific power delivery and source requirements of the application environment.

Battery Chargers Part Context

This part belongs to the BQ24298 series of charge management ICs from Texas Instruments. It is categorized under PMIC - Power Management ICs, specifically within the Battery Charger subcategory. The device is distinct from higher-current variants like the BQ25895 series, focusing on compact integration for standard USB-powered portable devices.

Battery Chargers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with other BQ2429x series variants only if pinout and electrical specifications match exactly.
