BQ24400PW

Battery Chargers Overview

The BQ24400PW 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 ambient temperature range of -20°C to +70°C and is housed in an 8-TSSOP package.

Battery Chargers Feature Summary

• Implements switch-mode topology for efficient energy conversion during the charging process.
• Integrates peak voltage detection circuitry to accurately terminate the charge cycle for NiCd and NiMH batteries.

Battery Chargers Applications

• Portable electronic devices requiring NiCd or NiMH battery management
• Consumer electronics utilizing rechargeable nickel-based power sources
• Industrial equipment with nickel-cadmium backup power systems

Battery Chargers Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm exact package dimensions and thermal characteristics. Ensure compatibility with the target NiCd or NiMH cell chemistry before integration. Confirm that the operating environment remains within the specified -20°C to +70°C range for reliable performance.

Battery Chargers Selection Notes

Select this component when designing systems specifically for Nickel-Cadmium or Nickel-Metal Hydride chemistries. The integrated peak voltage detection simplifies the design by removing the need for external termination logic. Consider the 8-TSSOP package constraints regarding thermal dissipation and board space availability.

Battery Chargers Part Context

This part belongs to the BQ24400 family of battery chargers from Texas Instruments. Variants such as BQ24400D offer different packaging options, while BQ24401 provides similar functionality with potential pinout differences. The PW suffix specifically denotes the 8-TSSOP surface-mount package configuration.

Battery Chargers Replacement Considerations

BQ24400D offers the same functional capabilities in a SOIC-8 package. BQ24400PWG4 indicates a lead-free compliant version of the same component. Verify pin-to-pin compatibility and thermal performance when substituting these variants.
