CSD95480RWJ

Full Half-Bridge (H Bridge) Drivers Overview

The CSD95480RWJ is a NexFET Smart Power Stage integrating a synchronous buck converter controller with dual power MOSFETs in a single package. It delivers a continuous output current of 70 A and supports a switching frequency of 1.25 MHz. The device operates within an input voltage range of 4.5 V to 16 V, while the control supply voltage is limited to 4.5 V to 5.5 V. It features a maximum duty cycle of 85% and includes integrated bootstrap circuitry. The component is housed in a 41-VQFN-CLIP (5x6 mm) surface-mount package.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the component status as Not Recommended for New Designs (NRND). Confirm that the specific suffix RWJ corresponds to the correct tape and reel packaging configuration. Ensure compatibility with existing board layouts due to the fixed 41-VQFN-CLIP footprint. Check for moisture sensitivity level requirements during assembly handling.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this part when a 70 A continuous current capability is required in a small form factor. The integrated nature reduces external component count compared to discrete solutions. Verify that the system input voltage does not exceed 16 V and that the logic supply remains within the 4.5 V to 5.5 V range. Consider thermal performance given the high current density in the VQFN-CLIP package.

Full Half-Bridge (H Bridge) Drivers Part Context

This device belongs to Texas Instruments' NexFET Smart Power Stage family, which combines GaN or silicon power switches with intelligent drivers. The CSD95480 series specifically targets high-current DC/DC conversion applications where space efficiency and simplified design are priorities.
