BQ24104RHLT

Battery Chargers Overview

The BQ24104RHLT is a standalone synchronous switched-mode battery charger IC from Texas Instruments, designed for single-cell and two-cell lithium-ion or lithium-polymer battery packs. It operates within an input voltage range of 4.3 V to 16 V and delivers a programmable output current up to 2 A with a fixed 4.2 V charging voltage. The device integrates thermal regulation and timer-based fault protection to ensure safe charging cycles. Packaged in a compact 20-pin VQFN (RHL) footprint measuring 3.5 mm by 4.5 mm, it supports surface-mount installation and functions reliably across an operating temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

• Synchronous switched-mode architecture for high-efficiency charging
• Integrated thermal regulation and timer-based fault protection
• Programmable charge current capability

Battery Chargers Applications

• Single-cell lithium-ion battery pack charging
• Two-cell lithium-ion battery pack charging
• Lithium-polymer battery management systems

Battery Chargers Procurement Notes

Verify the specific suffix 'G4' if environmental compliance data is required, as the base part number may differ in RoHS status documentation. Confirm package dimensions against the official datasheet to ensure PCB layout compatibility. Check for updated revision levels that may affect electrical characteristics or pinout definitions before finalizing procurement specifications.

Battery Chargers Selection Notes

Select this component for applications requiring high efficiency in space-constrained designs utilizing single or dual cell Li-Ion/Polymer batteries. Ensure the system input voltage remains within the 4.3 V to 16 V operational window. Verify that the required charge current does not exceed the 2 A maximum rating and that the thermal environment stays within the specified -40°C to +85°C range for reliable operation.

Battery Chargers Part Context

This device belongs to the BQ2410x family of synchronous buck battery chargers. It shares architectural similarities with the BQ24103 and BQ24105 but is specifically optimized for one or two series cells. The RHL package designation indicates a 20-pin VQFN form factor, distinguishing it from other pin counts or thermal pad configurations found in related TI battery management products.

Battery Chargers Replacement Considerations

The BQ24103ARHLT is a documented alternative within the same family, though it targets different cell configurations. Verify pin-to-pin compatibility and electrical parameter alignment with the official datasheet before substitution. No other direct cross-references are confirmed in public documentation.
