BQ24032ARHLT

Battery Chargers Overview

The BQ24032ARHLT is a single-cell lithium-ion and lithium-polymer battery charger IC from the bqTINY III series. It features dynamic power-path management to optimize system power distribution between the input source and the battery. The device supports dual inputs, typically an AC adapter or USB host, with a supply voltage range of 4.3 V to 16 V. It regulates the output to 4.2 V for the battery and provides a programmable charge current up to 1.5 A. The IC is housed in a compact 20-VQFN package (3.5x4.5 mm) and operates within a temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

• Integrates dynamic power-path management to balance system load and battery charging simultaneously
• Supports dual-input architecture allowing flexible connection to AC adapters or USB hosts
• Includes comprehensive fault protection mechanisms such as thermal regulation and reverse current blocking

Battery Chargers Applications

• Single-cell handheld portable devices
• Personal digital assistants (PDAs)
• MP3 players and audio devices
• GPS navigation units

Battery Chargers Procurement Notes

Verify the specific suffix 'HLTR' confirms the tape-and-reel packaging format required for automated assembly processes. Ensure compatibility with the target PCB footprint for the 20-VQFN package. Confirm that the selected component meets RoHS compliance standards for the intended market. Cross-reference the manufacturer datasheet for any recent design warnings or recommended circuit modifications.

Battery Chargers Selection Notes

Select this component when designing systems requiring simultaneous operation and charging from limited power sources. It is suitable for applications needing a small form factor due to the QFN package. Consider the maximum input voltage limits if using high-voltage adapters. Evaluate the need for external programming resistors to set specific charge currents and termination voltages according to the battery specifications.

Battery Chargers Part Context

This part belongs to the bqTINY III family of battery chargers designed for space-constrained mobile electronics. It shares functional similarities with other models in the BQ2403xA series but offers specific pinout and performance characteristics tailored for single-cell applications. The device integrates the power switch and control logic into a minimal footprint solution.

Battery Chargers Replacement Considerations

Compatible substitutes include BQ24030ARHLR and BQ24031ARHLR from the same manufacturer series. These alternatives share similar pinouts and functionality but may differ in specific current ratings or feature sets. Verify electrical parameters and package dimensions before substitution.
