BQ24081DRCRG4

Battery Chargers Overview

The BQ24081DRCRG4 is a single-cell Li-ion and Li-polymer linear charger IC from Texas Instruments, designed for space-constrained portable applications. It operates with an input supply voltage up to 6.5 V and delivers a programmable charging current of up to 1 A. The device features a 4.2 V output voltage for battery charging and includes integrated thermal regulation to manage junction temperature. Packaged in a compact 10-VSON (3x3 mm) format, it supports surface-mount installation and functions within an operating temperature range of -40°C to +125°C.

Battery Chargers Feature Summary

• Integrates power stage, charge termination logic, and thermal regulation into a single chip
• Supports automatic recharge functionality when battery voltage drops below the threshold
• Includes status indicator pin for monitoring charge state and fault conditions

Battery Chargers Applications

• Portable consumer electronics
• Handheld medical devices
• Industrial handheld instruments

Battery Chargers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS standards during procurement. Confirm package dimensions match the 10-VSON specification. Ensure the design accounts for the maximum input voltage rating of 6.5 V. Validate thermal performance under expected load conditions.

Battery Chargers Selection Notes

Select this component for designs requiring a compact solution for single-cell lithium batteries. It is suitable where input sources are limited to 6.5 V or lower. Consider the 1 A current limit for smaller capacity cells. Evaluate thermal dissipation requirements due to linear regulation characteristics.

Battery Chargers Part Context

This part belongs to the BQ2408x family of battery chargers. It shares functional similarities with other models in the series but differs in specific electrical ratings and packaging options. The G4 suffix typically denotes environmental compliance modifications within the product line.

Battery Chargers Replacement Considerations

Direct substitutes include BQ24080DRCR and BQ24082DRCR. Verify compatibility regarding input voltage ranges and maximum charging currents before substitution.
