CSD95482RWJT

Full Half-Bridge (H Bridge) Drivers Overview

The CSD95482RWJT is a synchronous buck converter from the NexFET Smart Power stage family by Texas Instruments. It integrates a high-side and low-side power MOSFET with a gate driver in a single package. The device supports an input voltage range of 4.5 V to 16 V and delivers up to 40 A of continuous output current. It operates at a switching frequency of 1.25 MHz with a maximum duty cycle of 85%. The unit functions within a junction temperature range of -40°C to +150°C and utilizes a 41-pin VQFN-CLIP package for surface mount installation.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify component authenticity through authorized channels, as counterfeit risks exist for high-volume power ICs. Confirm the specific suffix 'JT' indicates tape and reel packaging if required for automated assembly. Check for Obsolescence notices, as this part may be marked Not Recommended for New Designs (NRND). Ensure ESD handling protocols are followed due to the sensitivity of the integrated gate driver inputs.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component when a 40 A continuous current capability is required within a small footprint. The 1.25 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the thermal requirements of the application can be met by the VQFN-CLIP package's exposed pad design. Ensure the control loop compensation matches the internal driver characteristics for stable operation across the specified load range.

Full Half-Bridge (H Bridge) Drivers Part Context

This part belongs to the CSD9548x series of smart power stages designed for high-efficiency DC-DC conversion. It is functionally similar to the CSD95480RWJ and CSD95481RWJ but differs in its rated output current capacity. The series represents Texas Instruments' integration of power and control elements to reduce solution size and simplify PCB layout for demanding power applications.
