BQ24704RGET

Battery Chargers Overview

The BQ24704RGET is a host-controlled battery charger IC designed for lithium-ion and lithium-polymer batteries. It supports 2 to 4 series cells with an adjustable output voltage and delivers up to 8 A of output current. The device operates on a supply voltage ranging from 8 V to 18 V. It is housed in a 24-pin VQFN-EP package (4x4 mm) suitable for surface mount installation. The component functions within a temperature range of -40°C to +125°C.

Battery Chargers Feature Summary

• Host-controlled architecture enabling system management integration
• Supports multi-chemistry battery types including lithium-ion and lithium-polymer
• Integrated low input power detection capability

Battery Chargers Applications

• Portable electronic devices requiring efficient charging solutions
• Battery-powered products utilizing 2S to 4S cell configurations
• Systems integrating host microcontrollers for charge management

Battery Chargers Procurement Notes

Verify the specific suffix 'RGET' against the manufacturer datasheet to confirm tape-and-reel packaging and moisture sensitivity level. Ensure the ordering part number matches the required thermal pad configuration and pinout specifications for the target PCB layout. Cross-reference RoHS compliance status with the latest official documentation before finalizing procurement.

Battery Chargers Selection Notes

Select this component when a host processor manages the charging profile rather than autonomous control. It is appropriate for designs requiring input power limiting to protect upstream power sources. Consider the 24-pin VQFN package constraints for thermal dissipation and board space. Validate that the application voltage range aligns with the 8 V to 18 V operating specification.

Battery Chargers Part Context

This part belongs to the BQ2470x family of battery chargers from Texas Instruments. It shares architectural similarities with models like the BQ24707 but differs in pin count and specific feature sets. The RGET suffix indicates a specific reel quantity and package variant within the broader product line, distinguishing it from other packaging options available for the same core silicon.

Battery Chargers Replacement Considerations

Direct substitutes include other parts within the BQ2470x family such as the BQ24705 or BQ24707, provided pin compatibility and feature requirements match. Verify electrical parameters and package dimensions before swapping. Consult the manufacturer's substitution guide for validated alternatives.
