ISO5451QDWQ1

Isolators - Gate Drivers Overview

The ISO5451QDWQ1 is an automotive-grade, galvanically isolated gate driver designed for IGBT and MOSFET applications. It operates within a supply voltage range of 15 V to 30 V and delivers peak output currents of 2.5 A or 5 A. The device features a maximum propagation delay of 110 ns, with rise and fall times of 20 ns each. It supports both inverting and non-inverting configurations and includes integrated DESAT protection, Miller clamp, power good indication, fault output, and reset functionality. Qualified under AEC-Q100 standards, it functions reliably between -40°C and +125°C.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure the component meets AEC-Q100 grade requirements for your target automotive application. Cross-reference the full part number with Texas Instruments datasheets to validate pinout compatibility and thermal performance characteristics before integration.

Isolators - Gate Drivers Selection Notes

Select this component when high CMTI is required to prevent false triggering in high dv/dt environments. It is suitable for driving IGBTs and MOSFETs requiring up to 5 A peak current. Consider the SOIC-16 package constraints and thermal dissipation limits of 1.255 W during system design. Verify that the 15 V to 30 V supply range aligns with the target gate drive voltage requirements.

Isolators - Gate Drivers Part Context

This device belongs to the ISO5451 family of isolated gate drivers from Texas Instruments. It shares the SOIC-16 package form factor with other automotive interface components but is distinctively optimized for high-current gate driving rather than digital isolation or communication. It complements the broader ISO portfolio by addressing specific power stage control needs.

Isolators - Gate Drivers Replacement Considerations

Consult official substitution guides for equivalent isolated gate drivers with similar CMTI ratings and output current capabilities. Verify pin-to-pin compatibility if replacing existing designs. Ensure any substitute maintains AEC-Q100 qualification for automotive reliability standards.
