BQ24201DGNRG4

Battery Chargers Overview

The BQ24201DGNRG4 is a single-chip Li-Ion and Li-Pol charge management IC designed for current-limited applications. It features an integrated power path manager that optimizes system power distribution between the input source and the battery. The device supports a 4.2-V output voltage for single-cell lithium batteries and includes programmable charge current and termination current settings. It operates within a wide input voltage range and provides thermal regulation to manage heat dissipation during charging.

Battery Chargers Feature Summary

• Integrates a power path manager for optimized system power distribution
• Supports single-cell Li-Ion and Li-Po battery chemistries
• Includes thermal regulation to limit die temperature rise
• Provides charge status indication via dedicated pins

Battery Chargers Applications

• Portable consumer electronics with limited USB host power
• Battery-powered medical devices
• Industrial handheld instruments
• IoT sensor nodes requiring efficient charging

Battery Chargers Procurement Notes

Verify the specific suffix 'RG4' against the manufacturer's official documentation to confirm RoHS compliance and lead-free status. Ensure the MSOP-8 package variant matches the required PCB footprint and thermal pad specifications. Cross-reference the full part number with the latest datasheet revision to confirm pinout compatibility and electrical characteristics before finalizing procurement orders.

Battery Chargers Selection Notes

Select this component when designing systems powered by current-limited sources such as standard USB ports or wall adapters where input current must be strictly managed. It is suitable for applications requiring a compact solution with integrated power path management to prevent input brownouts. Consider the thermal performance in enclosed enclosures due to the small package size.

Battery Chargers Part Context

This part belongs to the BQ2420x family of single-chip chargers from Texas Instruments, which are tailored for portable applications. It shares functional similarities with the BQ24200 but offers specific packaging and compliance variations. The DGNR designation indicates the MSOP-8 package with a PowerPAD for improved thermal handling compared to standard SOIC packages.

Battery Chargers Replacement Considerations

The BQ24200DGNRG4 is a direct functional substitute within the same family. Verify that the replacement part maintains identical pinout configuration and thermal pad requirements. Confirm that any changes in suffix codes do not alter the RoHS status or operating temperature range specified in the original design.
