BQ24232HARGTT

Battery Chargers Overview

The BQ24232HARGTT 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 4.35V batteries with an output current of 500 mA and operates within a wide input voltage range of 4.35 V to 28 V. The component features dynamic power path management (DPPM) and input dynamic power management (VIN-DPM). It is housed in a 16-pin VQFN package measuring 3 mm x 3 mm, suitable for surface mount installation across temperatures from -40°C to +85°C.

Battery Chargers Feature Summary

• Integrates dynamic power path management to supply system loads while independently charging the battery
• Supports USB-friendly operation with programmable input current limits and surge current control
• Includes comprehensive protection against over-temperature, over-voltage, reverse current, and short circuits

Battery Chargers Applications

• Portable devices requiring compact battery charging solutions
• USB-powered consumer electronics
• Applications utilizing unregulated wall adapters

Battery Chargers Procurement Notes

Verify the specific suffix 'ARGTT' against official Texas Instruments documentation to confirm temperature grade and tape/reel specifications. Ensure compatibility with the 16-VQFN footprint and check for moisture sensitivity level requirements during storage and handling. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and avoid counterfeit components.

Battery Chargers Selection Notes

Select this component when designing systems that require simultaneous system power and battery charging without external MOSFETs. It is suitable for applications needing high input voltage tolerance up to 28 V and precise USB input current limiting. Consider the small 3x3 mm package size for tight board space constraints and verify thermal performance under maximum load conditions.

Battery Chargers Part Context

This device belongs to the bqTINY family of battery chargers, which are optimized for single-cell lithium-based batteries. The BQ24232H variant specifically targets 4.35V chemistry support. The 'A' suffix typically denotes a specific temperature rating or manufacturing lot code, while 'RTT' indicates the reel packaging format for automated assembly.

Battery Chargers Replacement Considerations

Consult official substitution lists for direct replacements. Generic equivalents may lack integrated power path management or specific USB compliance features.
