BQ24753ARHDR

Battery Chargers Overview

The BQ24753ARHDR is a host-controlled synchronous battery charger designed for lithium-ion and lithium-polymer batteries. It operates within an input voltage range of 7 V to 24 V and supports an output current of 10 A. The device features adjustable output voltage and utilizes a VQFN-28 package for surface-mount installation. It functions across a temperature range of -40 °C to +85 °C.

Battery Chargers Feature Summary

• Integrates system power selector logic for efficient power distribution
• Includes high-accuracy current-sense amplifier for input current monitoring
• Features low quiescent current operation to minimize standby losses

Battery Chargers Applications

• Host-controlled charging systems for portable devices
• Battery management in consumer electronics using Li-Ion or Li-Poly cells
• Power supply units requiring precise input current regulation

Battery Chargers Procurement Notes

Verify the specific suffix 'RHDR' corresponds to the tape-and-reel packaging configuration as indicated by distributor listings. Confirm that the VQFN-28 footprint matches your PCB design requirements. Ensure the operating environment stays within the specified -40 °C to +85 °C range. Check for RoHS compliance documentation if required for your manufacturing standards. Validate compatibility with your host controller interface before finalizing procurement.

Battery Chargers Selection Notes

Select this component when a host processor manages the charging profile rather than autonomous control. It is suitable for applications requiring integrated system power path management. The device is appropriate for designs needing accurate input current limiting to protect upstream power sources. Consider the VQFN-28 package size constraints during layout planning. Ensure the application supports the 7 V to 24 V input voltage window.

Battery Chargers Part Context

This part belongs to the BQ24753A series of battery chargers from Texas Instruments. It is distinct from the BQ24751, which supports additional battery chemistries like lead-acid and NiMH. The BQ24753 focuses specifically on lithium-based chemistries with host-controlled functionality. It shares the same package form factor as other devices in the family but differs in supported battery types and control architecture.
