BQ24232HRGTR

Battery Chargers Overview

The BQ24232HRGTR is a highly integrated lithium-ion linear charger and system power path management device from Texas Instruments, designed for space-constrained portable applications. It supports charging currents ranging from 25mA to 500mA and operates with a maximum input voltage of 28V. The device features a 4.35V battery regulation voltage and utilizes a 16-pin VQFN package measuring 3mm x 3mm. It includes dynamic power path management (DPPM) to supply the system while charging the battery independently.

Battery Chargers Feature Summary

• Integrates dynamic power path management to maintain system operation during charging
• Supports USB-friendly input current limiting compliant with USB-IF standards
• Includes comprehensive protection against over-temperature, reverse current, and short circuits

Battery Chargers Applications

• Portable consumer electronics requiring compact battery charging solutions
• USB-powered devices needing precise input current management
• Applications utilizing unregulated wall adapters with high input voltage tolerance

Battery Chargers Procurement Notes

Verify the specific suffix HRGTR corresponds to the reel packaging configuration when ordering. Confirm that the 4.35V output specification aligns with the target battery chemistry requirements. Ensure the 16-VQFN footprint matches the design layout constraints. Cross-reference the datasheet for thermal performance expectations under maximum load conditions.

Battery Chargers Selection Notes

Select this component for designs prioritizing small form factors and integrated power path functionality. It is suitable for systems where maintaining operation without a battery or during low-input scenarios is critical. Consider the programmable charge current limits and the need for external NTC thermistor support for thermal monitoring.

Battery Chargers Part Context

This part belongs to the bqTINY family of battery chargers, which are optimized for single-cell lithium-based batteries. The BQ24232H series specifically targets applications requiring USB compatibility and robust power path management within a minimal footprint, distinguishing it from higher-current multi-cell solutions.

Battery Chargers Replacement Considerations

Direct substitutes include other variants within the BQ24232H series, such as BQ24232HRGTT, provided the packaging format difference between tape-and-reel and cut-tape is acceptable. Verify pinout and electrical specifications remain identical before substitution.
