BQ24201DGNR

Battery Chargers Overview

The BQ24201DGNR is a single-cell lithium-ion and lithium-polymer battery charger integrated circuit manufactured by Texas Instruments. It operates within an input supply voltage range of 4.35 V to 28 V and delivers a fixed charge current of 500 mA. The device provides a regulated output voltage of 4.35 V, suitable for high-voltage cells. Packaged in an 8-MSOP (0.118 inch width) surface-mount package, it supports operation across a temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

• Integrates power path management for system load prioritization during input presence
• Supports USB-friendly charging profiles compliant with standard host port limits
• Includes thermal regulation to reduce charge current based on junction temperature

Battery Chargers Applications

• Portable consumer electronics powered by single-cell Li-Ion or Li-Po batteries
• USB-powered devices requiring integrated charge management
• Battery backup systems for microcontrollers and sensors

Battery Chargers Procurement Notes

Verify the specific suffix 'DGNR' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration. Ensure compatibility with the required 8-MSOP footprint dimensions. Cross-reference the part number with the latest Texas Instruments documentation to validate active status and any recent design changes.

Battery Chargers Selection Notes

Select this component for applications requiring a compact solution for single-cell chemistry charging. The fixed 500 mA output current suits low-power portable devices. Confirm that the input source can sustain the required voltage headroom above the 4.35 V cell voltage. Evaluate thermal dissipation requirements given the small MSOP package size under continuous charging loads.

Battery Chargers Part Context

This device belongs to the bqTINY family of battery chargers from Texas Instruments. It is designed as a cost-effective, space-saving alternative to discrete charging solutions. The series focuses on integrating essential protection features and power path control into a minimal footprint for mobile and IoT applications.

Battery Chargers Replacement Considerations

The BQ24205DGN is a pin-compatible alternative within the same family offering similar functionality. Verify electrical parameter alignment before substitution.
