BQ24203DGN

Battery Chargers Overview

The BQ24203DGN is a single-chip Li-Ion and Li-Pol charge management IC designed for current-limited wall supplies. Manufactured by Texas Instruments, this component integrates linear charge management functions within an 8-MSOP package with a PowerPad. It supports charging currents up to 1A and operates from input voltages as low as 4.5V. The device features programmable charge termination, thermal regulation, and status indication, making it suitable for portable applications requiring efficient power management from standard USB or AC adapters.

Battery Chargers Feature Summary

• Integrated linear charge management for Li-Ion and Li-Polymer batteries
• Designed specifically for current-limited wall supply applications
• Includes thermal regulation and charge termination logic

Battery Chargers Applications

• Portable electronic devices powered by current-limited sources
• USB-powered battery charging systems
• AC adapter-based consumer electronics

Battery Chargers Procurement Notes

Verify the manufacturer origin carefully, as Benchmarq is primarily an insurance provider and does not manufacture semiconductor components. The BQ24203DGN is a Texas Instruments product. Ensure the supplier provides authentic TI documentation and traceability. Confirm the package type matches the required MSOP-8 specification with PowerPad for proper thermal and electrical performance in your design.

Battery Chargers Selection Notes

Select this component when designing for environments with limited input current capability, such as standard USB ports or small wall adapters. It is appropriate for single-cell lithium-ion or lithium-polymer battery applications. Consider the thermal performance of the MSOP package if high ambient temperatures are expected. Verify compatibility with the target battery chemistry and required charge termination voltage before integration.

Battery Chargers Part Context

This part belongs to the bq2420x series of charge management ICs from Texas Instruments. These devices are optimized for simplicity and efficiency in portable applications. The series targets designs where space and cost are critical constraints while maintaining reliable charging profiles for lithium-based batteries from constrained power sources.

Battery Chargers Replacement Considerations

Check for direct pin-compatible alternatives within the bq2420x family or newer generations from Texas Instruments. Ensure any substitute maintains support for current-limited inputs and compatible package dimensions. Verify that replacement parts offer equivalent thermal management capabilities and meet the same safety standards for lithium battery charging.
