BQ24741RHDR

Battery Chargers Overview

The BQ24741RHDR is a lithium-ion or lithium-polymer battery charger IC designed for single-cell applications. It supports input voltages up to 28V and delivers a maximum charge current of 1A. The device features an integrated power path management system, allowing operation from USB ports or wall adapters while simultaneously powering the system load. Key electrical parameters include a 5.85V overvoltage protection threshold on the input and a low quiescent current consumption. It operates within a junction temperature range of -40°C to 125°C and is housed in a compact 6-pin SOT-23 package.

Battery Chargers Feature Summary

• Integrates power path management to prioritize system load supply during charging
• Provides accurate trickle charging with configurable thresholds for deeply discharged batteries
• Includes comprehensive fault protection against over-voltage, over-temperature, and short circuits

Battery Chargers Applications

• Portable consumer electronics powered by single-cell Li-Ion or Li-Polymer batteries
• USB-powered devices requiring simultaneous charging and system operation
• Battery backup systems for embedded controllers and IoT modules

Battery Chargers Procurement Notes

Verify component authenticity through authorized Texas Instruments distributors or certified partners. Confirm the specific suffix RHDR corresponds to the required tape-and-reel packaging format. Check for obsolescence notices or lifecycle status updates prior to finalizing procurement plans to ensure long-term supply stability.

Battery Chargers Selection Notes

Select this component when designing systems requiring a single-cell charger with integrated power path switching. It is suitable for applications where the input source must support both charging and immediate system load demands without external switching components. Ensure the design accommodates the 28V maximum input rating and 1A current limit constraints.

Battery Chargers Part Context

This part belongs to the BQ2474x family of battery chargers from Texas Instruments. It shares functional similarities with the BQ24742 but is optimized for single-cell configurations. The family focuses on cost-effective solutions for portable devices, offering high integration levels to minimize external component counts and PCB area requirements.

Battery Chargers Replacement Considerations

Direct pin-to-pin replacements may include other single-cell chargers from the same manufacturer series. Verify compatibility regarding input voltage ranges and thermal performance before substitution.
