BQ24400PWR

Battery Chargers Overview

The BQ24400PWR is a switch-mode battery charger designed for Nickel-Cadmium (NiCd) and Nickel-Metal Hydride (NiMH) cells. It utilizes peak voltage detection termination to manage charging cycles efficiently. The device operates within an input voltage range of 4.5 V to 6 V and supports programmable charge currents up to 1 A. It features a compact 8-pin TSSOP package with an operating temperature range of -20°C to +70°C.

Battery Chargers Feature Summary

• Implements peak voltage detection termination for NiCd/NiMH batteries
• Supports programmable charge current control
• Integrated switching regulator architecture

Battery Chargers Applications

• Portable electronic devices requiring NiCd or NiMH power sources

Battery Chargers Procurement Notes

Verify the specific suffix 'PWR' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official Texas Instruments documentation, as manufacturing revisions may affect material specifications. Ensure the supplier provides valid traceability data for quality assurance purposes.

Battery Chargers Selection Notes

Select this component for applications requiring efficient charging of single-cell NiCd or NiMH batteries. It is suitable where space constraints favor the TSSOP package. Consider thermal performance requirements relative to the specified operating temperature range during system design.

Battery Chargers Part Context

This part belongs to the BQ2440x family of battery chargers from Texas Instruments. It shares functional similarities with variants like the BQ24400PW but differs in packaging format. The PWR suffix specifically denotes the reel-based packaging configuration used for automated surface-mount assembly processes.

Battery Chargers Replacement Considerations

Direct substitutes include the BQ24400PW and BQ24400PWG4. Verify pin compatibility and electrical parameters before substitution. Alternative packages such as DFN may require schematic and layout modifications.
