BQ24031RHLR

Battery Chargers Overview

The BQ24031RHLR is a single-chip charge and system power-path management IC from the bqTINY family. It integrates a synchronous switch-mode charger for single-cell lithium-ion or lithium-polymer batteries with an integrated system power path. The device manages charging current and voltage while prioritizing system load requirements. It operates within a specified input voltage range and supports adjustable charge termination thresholds.

Battery Chargers Feature Summary

• Integrates synchronous rectification for high-efficiency battery charging
• Manages system power path to prioritize loads during input power limitations
• Supports auto-start functionality when input voltage exceeds battery voltage

Battery Chargers Applications

• Portable consumer electronics requiring compact power solutions
• Single-cell lithium-ion battery powered devices
• Systems with limited USB or wall adapter input power budgets

Battery Chargers Procurement Notes

Verify the specific suffix and revision code against the manufacturer's official datasheet to ensure compatibility with required operating temperatures and regulatory standards. Confirm package markings match the intended application design. Cross-reference ordering information with authorized distributors to avoid counterfeit components.

Battery Chargers Selection Notes

Select this component for applications requiring a minimal footprint solution for single-cell battery charging. Ensure the input source can provide sufficient current for both charging and system operation. Evaluate thermal performance based on the expected ambient temperature and PCB copper area available for heat dissipation in the QFN package.

Battery Chargers Part Context

This part belongs to Texas Instruments' bqTINY series, designed for space-constrained portable devices. It serves as a complete power management solution combining charging and system distribution. The series emphasizes low component count and high integration levels compared to discrete charging solutions.

Battery Chargers Replacement Considerations

Compatible alternatives include the BQ24030 and BQ24070 series. Verify pinout compatibility and electrical specifications before substitution. The BQ24031-Q1 variant offers automotive qualification if required.
