Battery Chargers datasheet and documents for BQ24031RHLT

BQ24031RHLT

Battery Chargers Overview

The BQ24031RHLT is a single-chip charge and system power-path management IC from the bqTINY family. It supports Li-Ion and Li-Polymer batteries with an input voltage range of 4.35 V to 16 V. The device provides a programmable charging current up to 1.5 A and regulates the battery output to 4.2 V. It features a 100 kΩ NTC thermistor for thermal regulation and operates within a junction temperature range of -40 °C to 85 °C. The component is housed in a 20-VQFN package measuring 3.5 mm by 4.5 mm.

Battery Chargers Feature Summary

Integrates dynamic power path management to prioritize system load while charging the battery
Includes built-in thermal regulation using an external 100 kΩ NTC thermistor
Supports USB host or wall adapter inputs with automatic source detection
Provides comprehensive fault protection against over-temperature, reverse current, and short circuits

Battery Chargers Applications

Portable consumer electronics powered by USB
Smartphones and mobile phones
Personal digital assistants (PDAs)
MP3 players and portable media devices

Battery Chargers Procurement Notes

Verify the specific suffix RHLT confirms the 20-VQFN package and tape-and-reel packaging format. Ensure the design utilizes a 100 kΩ NTC thermistor for the thermal regulation pin as specified in the datasheet. Confirm RoHS compliance status matches current manufacturing standards before finalizing procurement orders.

Battery Chargers Selection Notes

Select this component for applications requiring integrated power path management and compact footprint. It is suitable for systems needing up to 1.5 A charging current from standard USB sources. Consider alternative models if higher input voltage tolerance or automotive-grade reliability is required.

Battery Chargers Part Context

This part belongs to the bqTINY III series of battery chargers. It shares functional similarities with the BQ24030 and BQ24032 but offers specific integration levels for cost-sensitive portable designs. The device simplifies design by combining linear charging and power path control in a single small package.
