ISO5852SDW

Isolators - Gate Drivers Overview

The ISO5852SDW is a single-channel isolated gate driver from the ISO5852S series, manufactured by Texas Instruments. It features 5.7kVrms galvanic isolation and supports split output configurations with peak currents of 2.5A (source) and 5A (sink). The device operates within a supply voltage range of 15V to 30V and includes integrated protection features such as DESAT detection, Miller clamp, and soft turn-off. It offers a maximum propagation delay of 110ns, rise time of 18ns, and fall time of 20ns. Operating temperatures span from -40°C to +125°C in a 16-pin SOIC package.

Isolators - Gate Drivers Feature Summary

• Integrated DESAT protection for monitoring power device health
• Split output architecture enabling independent control of source and sink paths
• Miller clamp functionality to prevent false triggering during high dv/dt events
• Soft Turn-Off (STO) capability to manage switching transitions

Isolators - Gate Drivers Applications

• Silicon Carbide (SiC) power module gate driving
• Insulated Gate Bipolar Transistor (IGBT) switching applications
• High-voltage industrial motor drives
• Isolated power conversion systems requiring robust fault protection

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'DW' confirms the 16-pin SOIC package and commercial temperature grade (-40°C to +125°C). Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure input signals match the logic level requirements specified in the electrical characteristics table of the official datasheet.

Isolators - Gate Drivers Selection Notes

Select this component when designing circuits for SiC or IGBT modules requiring high common-mode transient immunity and integrated fault management. The split output feature is critical for optimizing switching speed and minimizing cross-conduction risks. Consider the 5.7kVrms isolation rating against the system's working voltage and creepage/clearance requirements. Evaluate the need for Soft Turn-Off to reduce electromagnetic interference in sensitive environments.

Isolators - Gate Drivers Part Context

This part belongs to the ISO5852S family of isolated gate drivers designed specifically for wide-bandgap semiconductors. It complements evaluation tools like the ISO5852SDWEVM-017 for rapid prototyping. The device addresses the need for compact, high-performance isolation in modern power electronics, replacing discrete solutions with an integrated approach that simplifies layout and improves reliability.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes include other parts within the ISO5852S family, such as the ISO5852SMDWREP, which shares identical electrical specifications but may differ in packaging format (e.g., Digi-Reel vs. standard reel). Verify pinout compatibility and thermal performance before swapping.
