BQ24073RGTT

Battery Chargers Overview

The BQ24073RGTT is a USB-friendly Li-Ion battery charger and power-path management IC from Texas Instruments. It operates within an input voltage range of 4.35 V to 6.4 V and supports a maximum charge current of 1.5 A. The device provides a regulated output voltage of 4.2 V for single-cell lithium-ion batteries. It features programmable charge current and timer functions, along with comprehensive fault protection including over-temperature, over-voltage, reverse current, and short-circuit safeguards. The component is housed in a 16-VQFN package measuring 3x3 mm.

Battery Chargers Feature Summary

• Integrates linear charging with system power path management for portable applications
• Supports non-regulated adapters with input voltage protection and dynamic power management
• Complies with USB-IF surge current specifications through precise input current limiting

Battery Chargers Applications

• Portable devices requiring space-constrained power solutions
• USB-powered consumer electronics
• Single-cell lithium-ion battery systems

Battery Chargers Procurement Notes

Verify the specific suffix 'RGTT' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration. Ensure compatibility with the required operating temperature range and lead-free RoHS standards before procurement. Cross-reference the part number with authorized distributors to validate authenticity and supply chain integrity.

Battery Chargers Selection Notes

Select this component for designs needing integrated power path management alongside charging. It is suitable for applications powered by USB ports or AC adapters where input surge compliance is critical. Consider the 16-VQFN footprint for PCB layout constraints and verify thermal dissipation requirements for the 1.5 A charge current capability.

Battery Chargers Part Context

This IC belongs to the BQ2407x family of battery chargers designed for USB-friendly applications. It shares functional similarities with models like the BQ24072 and BQ24079 but offers specific parameter configurations for single-cell lithium-ion systems. The device simplifies design by combining charger and power path management in a compact package.

Battery Chargers Replacement Considerations

Compatible substitutes include BQ24072RGTTG4 and BQ24079TRGTT. Verify pinout compatibility and electrical parameters such as input voltage range and charge current limits before substitution.
