BQ24780SRUYR

Battery Chargers Overview

The BQ24780 is a highly integrated battery charger and system power path manager designed for notebook, tablet, and industrial applications. It supports single-cell Li-ion or Li-polymer batteries with an input voltage range of 4.75V to 28V. The device integrates a synchronous buck converter capable of delivering up to 6A of charging current. It features a programmable system load limit to prevent host dropout when using limited USB or AC adapters. Integrated FETs eliminate the need for external switching components, reducing solution size.

Battery Chargers Feature Summary

• Integrated synchronous buck converter with internal high-side and low-side N-channel MOSFETs
• Programmable system load limit control to manage input current from various sources
• Supports multiple charging profiles including constant current/constant voltage (CC/CV) and trickle charge
• Comprehensive protection features including thermal regulation and input undervoltage lockout

Battery Chargers Applications

• Notebook computers and ultrabooks
• Tablets and mobile computing devices
• Industrial equipment requiring reliable battery management
• Portable medical devices

Battery Chargers Procurement Notes

Verify the specific suffix 'SRUYR' against the manufacturer's official datasheet to confirm package type (WQFN), temperature grade, and reel quantity. Ensure compatibility with your PCB footprint and thermal requirements. Cross-reference the date code and lot traceability if required for your supply chain standards. Confirm that the component meets RoHS and REACH directives as specified in the latest documentation.

Battery Chargers Selection Notes

Select this component when a compact, high-efficiency solution is needed for single-cell lithium batteries. It is suitable for designs requiring precise input current limiting to support USB PD or standard AC adapters without host system instability. Consider this part if minimizing external component count and board space is a priority while maintaining robust charging safety features.

Battery Chargers Part Context

This part belongs to Texas Instruments' BQ24xxx family of battery chargers. It is designed to replace discrete solutions by integrating power switches and control logic. The device is commonly used in portable electronics where space constraints and efficiency are critical. It complements other PMICs in complex power systems by handling the primary charging function.

Battery Chargers Replacement Considerations

Check for direct pin-to-pin replacements within the BQ247xx series. Verify that alternative parts support the same input voltage range and output current capabilities. Ensure that any substitute maintains compatible control interfaces and protection thresholds. Consult official substitution guides for validated alternatives.
