BQ24023DRCRG4

Battery Chargers Overview

The BQ24023DRCRG4 is a single-chip lithium-ion and lithium-polymer charger IC from Texas Instruments. It features autonomous USB-port and AC-adapter inputs, supporting dual-input power management. The device operates within a voltage range of 4.35V to 5.5V and supports charge currents up to 1A. It utilizes a 10-VSON package with dimensions of 3mm x 3mm. The operating temperature range spans from -40°C to +85°C.

Battery Chargers Feature Summary

• Autonomous switching between USB and AC adapter power sources without external control logic
• Integrated thermal regulation to manage heat dissipation during charging cycles
• Supports both lithium-ion and lithium-polymer battery chemistries

Battery Chargers Applications

• Portable consumer electronics requiring compact power management
• USB-powered devices needing automatic source detection
• Battery-powered handheld instruments

Battery Chargers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per Texas Instruments documentation. Confirm the 10-VSON package marking code matches your assembly requirements. Ensure the input voltage range aligns with your system's USB or AC adapter specifications before procurement.

Battery Chargers Selection Notes

Select this component for applications requiring integrated dual-input source management in a minimal footprint. It is suitable for designs where automatic transition between USB and wall adapter power is necessary without additional microcontroller intervention. Consider the 1A current limit when sizing the PCB copper traces for thermal performance.

Battery Chargers Part Context

This part belongs to the bqTINY-II family of chargers, designed for space-constrained portable devices. It integrates linear charging technology with source detection capabilities. The series focuses on reducing bill-of-materials count by combining charger management and input selection into a single small-outline package.

Battery Chargers Replacement Considerations

Check for direct pin-compatible alternatives within the bq240xx series if higher current ratings are needed. Verify that any substitute maintains the same 10-VSON footprint and autonomous input switching functionality to ensure board compatibility.
