UCC27444QDGNRQ1

Gate Driver Overview

The UCC27444QDGNRQ1 is an automotive-grade, dual-channel low-side gate driver manufactured by Texas Instruments. It features a HVSSOP-8 package and supports supply voltages from 4.5 V to 18 V. The device provides 4 A peak output current with non-inverting logic compatibility for CMOS and TTL inputs. Key timing parameters include a maximum propagation delay of 33 ns, rise time of 11 ns, and fall time of 7 ns. It operates within a temperature range of -40°C to +125°C and draws 39 mA of quiescent current.

Gate Driver Feature Summary

• Dual-channel low-side configuration designed for driving two MOSFETs simultaneously
• Automotive qualification ensuring reliability under harsh environmental conditions
• High-speed switching capability with fast rise and fall times for efficient power control

Gate Driver Applications

• Automotive powertrain systems requiring robust gate drive solutions
• Motor control applications utilizing low-side switching architectures
• Inverter circuits in electric vehicle power electronics

Gate Driver Procurement Notes

Verify the specific suffix QDGNRQ1 matches the required HVSSOP-8 package and automotive grade designation. Confirm that the component meets AEC-Q100 standards if explicitly documented in the official datasheet. Ensure input voltage levels align with the specified 4.5 V to 18 V operating range before integration into the final design.

Gate Driver Selection Notes

Select this component when a dual-channel low-side driver with automotive certification is required. It is suitable for applications needing high peak current capability without the complexity of bootstrap circuits associated with high-side drivers. Consider the non-inverting logic interface for direct compatibility with standard microcontroller outputs.

Gate Driver Part Context

This part belongs to the UCC27444 series of high-speed gate drivers. It shares functional similarities with other low-side drivers but is distinguished by its automotive qualification and dual-channel layout. The QDGNRQ1 variant specifically denotes the qualified version in the HVSSOP-8 package, differentiating it from commercial counterparts or alternative package options.

Gate Driver Replacement Considerations

UCC27444DGNR is the commercial equivalent without automotive qualification. UCC27423QDGNRQ1 offers similar performance but features an inverting logic configuration instead of non-inverting.
