CSD88584Q5DCT

Overview

The CSD88584Q5DCT is a 40-V Half-Bridge NexFET Power Block manufactured by Texas Instruments. It integrates two N-channel MOSFETs in an 8-pin DFN package (5x6 mm). The device features low on-resistance and fast switching characteristics suitable for high-efficiency power conversion. Key electrical parameters include a drain-source voltage of 40 V, gate-source voltage of ±20 V, and maximum continuous drain current of 30 A at case temperature. The junction temperature range extends from -55°C to 150°C.

Feature Summary

• Integrated half-bridge configuration with common source connection
• NexFET technology for enhanced efficiency and thermal performance
• Low profile surface-mount packaging for space-constrained designs

Applications

• DC-DC converter modules
• Motor driver circuits
• Power management units

Procurement Notes

Verify the exact suffix 'CT' against official TI documentation to confirm cut-tape packaging status, as datasheets typically list standard reel quantities. Ensure component authenticity through authorized distribution channels and check RoHS compliance records prior to integration into production lines.

Selection Notes

Select this component for applications requiring a compact half-bridge solution with 40-V rating. Evaluate thermal resistance values against system heat dissipation requirements. Confirm gate drive compatibility with the specified threshold voltages and total gate charge specifications for optimal switching performance.

Part Context

This part belongs to the NexFET Power Block family, which combines complementary MOSFETs to reduce board space and parasitic inductance. It serves as a direct replacement for discrete half-bridge arrangements in synchronous buck converters and other power stages requiring integrated switching elements.

Replacement Considerations

Check for equivalent parts such as CSD87355Q5D or similar NexFET blocks with matching voltage and current ratings. Verify pinout compatibility and thermal pad dimensions before substituting to ensure mechanical and electrical fit within the existing design.
