BQ24004PWPR

Battery Chargers Overview

The BQ24004PWPR is a two-cell lithium-ion charge management integrated circuit manufactured by Texas Instruments. Designed for portable applications, it supports lithium-ion and lithium-polymer battery chemistries. The device operates within an input voltage range of 8.4 V to 10 V and provides a regulated output voltage of 8.4 V with a maximum output current of 1.2 A. It is housed in a thermally enhanced HTSSOP-20 package suitable for surface mount installation. The component functions within a temperature range of -20°C to +70°C.

Battery Chargers Feature Summary

• Integrated linear charge management controller optimized for two-cell series configurations
• Supports standard charging profiles including constant current and constant voltage termination
• Thermally enhanced PowerPAD package design for efficient heat dissipation

Battery Chargers Applications

• Portable digital assistants (PDAs)
• Internet appliances
• Two-cell lithium-ion battery packs

Battery Chargers Procurement Notes

Verify the specific suffix 'PWPR' against the manufacturer datasheet to confirm the package type and reel specifications. Ensure compatibility with the required thermal management solution for the HTSSOP-20 package. Confirm that the application environment remains within the specified operating temperature limits of negative twenty degrees Celsius to positive seventy degrees Celsius.

Battery Chargers Selection Notes

Select this component when designing systems requiring dedicated charge management for two-series lithium cells. It is appropriate for space-constrained designs due to its compact HTSSOP-20 footprint. Engineers should evaluate the thermal performance requirements relative to the 1.2 A output capability and ensure the power supply input aligns with the 8.4 V to 10 V operational window.

Battery Chargers Part Context

This part belongs to the BQ2400x family of single-chip charge management ICs from Texas Instruments. It serves as a specialized solution for low-power portable electronics, distinct from higher-current switching regulators or single-cell variants like the BQ24001. The PWPR designation indicates the specific tape-and-reel packaging format used for automated assembly processes.

Battery Chargers Replacement Considerations

Direct functional substitutes include the BQ24004PWP for non-reel packaging. For single-cell applications, the BQ24001 is a related alternative. Higher integration levels may require the BQ24085.
