BQ24278RGET

Battery Chargers Overview

The BQ24278RGET is a single-input, single-cell switch-mode Li-ion battery charger from Texas Instruments. It integrates power path management for system power sharing. The device supports an input voltage range of 4 V to 10.5 V and delivers up to 2.5 A output current. It features a fixed 4.2 V charge voltage for lithium-ion cells. The component operates within a temperature range of -40 °C to +85 °C. It is housed in a 24-pin VQFN package with dimensions of 4x4 mm.

Battery Chargers Feature Summary

• Integrates power path management for automatic source selection between adapter and battery
• Supports single-cell lithium-ion battery charging via switch-mode topology
• Includes programmable input current limit to protect upstream power sources

Battery Chargers Applications

• Portable consumer electronics requiring efficient single-cell charging
• Battery-powered devices with USB or wall adapter power inputs
• Systems requiring integrated power path management for seamless operation

Battery Chargers Procurement Notes

Verify the specific suffix RGET confirms the reel packaging format when ordering. Confirm the 24-pin VQFN footprint matches your PCB layout requirements. Ensure the design accommodates the specified 4 V to 10.5 V input range. Check for any recent product change notifications regarding pinout or thermal characteristics before finalizing procurement.

Battery Chargers Selection Notes

Select this component for applications requiring a single-input solution with integrated power path management. It is suitable for systems needing up to 2.5 A charging current from a 4 V to 10.5 V source. Consider the VQFN-24 package size for space-constrained designs. Verify compatibility with single-cell lithium-ion chemistry constraints.

Battery Chargers Part Context

This part belongs to the BQ24278 series of battery chargers. It is designed as a compact solution for single-cell applications. The series emphasizes efficiency and integration by combining the charger controller with power switches. It targets portable devices where board space and component count are critical factors.

Battery Chargers Replacement Considerations

Check datasheets for alternative TI models like the BQ24271RGET if lower current (1.5 A) or different input voltage ranges are required. Verify pin-to-pin compatibility before substituting. Ensure the replacement supports the same 24-pin VQFN package and single-cell architecture.
