BQ24078RGTR

Battery Chargers Overview

The BQ24078RGTR is a standalone single-cell linear battery charger and power-path management IC manufactured by Texas Instruments. It supports lithium-ion and lithium-polymer batteries with a regulated output voltage of 4.35 V and a programmable input current limit up to 1.5 A. The device operates from an input supply voltage range of 4.35 V to 6.4 V. It integrates automatic recharge, thermal regulation, and input undervoltage lockout. The component is housed in a 16-pin Very Thin Quad Flat No-lead (VQFN) package measuring 3 mm by 3 mm, designed for surface-mount installation.

Battery Chargers Feature Summary

• Integrates power-path management to prioritize system load while charging the battery
• Includes thermal regulation to reduce input current based on junction temperature
• Supports USB-compatible host ports with programmable input current limits
• Features automatic recharge triggered when battery voltage drops below threshold

Battery Chargers Applications

• Portable consumer electronics powered by single-cell lithium batteries
• USB-powered devices requiring integrated charge management
• Handheld gadgets with limited input power availability

Battery Chargers Procurement Notes

Verify the specific suffix RGTR corresponds to the tape-and-reel packaging configuration required for automated assembly lines. Confirm that the 16-VQFN footprint matches the target PCB land pattern dimensions. Ensure compatibility with the intended input voltage source within the specified operational range before finalizing procurement orders.

Battery Chargers Selection Notes

Select this component when a compact solution for single-cell lithium battery charging is required alongside system power distribution. It is suitable for applications where space constraints necessitate a small VQFN package. Choose this part if the design requires automatic power-path switching between the input source and the battery without external control signals.

Battery Chargers Part Context

This IC belongs to the BQ2407x family of linear chargers from Texas Instruments. It shares functional similarities with models like the BQ24076 and BQ24072 but differs in specific output voltage settings and feature configurations. The series is designed for cost-effective, high-volume portable applications requiring reliable battery management.

Battery Chargers Replacement Considerations

The BQ24076RGTR serves as a public confirmed substitute part number within the same product family.
