UCC27524AQDGNRQ1

Gate Driver Overview

The UCC27524AQDGNRQ1 is a dual high-speed low-side gate driver from Texas Instruments, designed for driving power MOSFETs and IGBTs. It delivers a peak output current of 5A source and sink. The device operates within a supply voltage range of 4.5V to 18V. Key timing parameters include a typical propagation delay of 13ns, with rise and fall times of 7ns. It features an enable pin and non-inverting configuration. Qualified under AEC-Q100 standards, it supports junction temperatures up to 140°C and is housed in an MSOP-PowerPad-8 package.

Gate Driver Feature Summary

• Dual-channel architecture with matched internal propagation delays for critical timing applications like synchronous rectification.
• High-peak current capability delivering 5A source and sink pulses into capacitive loads.
• Inherent design minimizes shoot-through current while providing rail-to-rail drive capability.
• Channels can be paralleled to increase current drive or drive two switches with a single input signal.

Gate Driver Applications

• Synchronous rectifiers requiring precise dual-gate timing
• Automotive power electronics systems
• Industrial motor drives
• DC-DC converter topologies

Gate Driver Procurement Notes

Verify the specific suffix 'DGNRQ1' against official Texas Instruments documentation to confirm the tape-and-reel packaging format and automotive qualification status. Ensure the ordering part number matches the exact package type and temperature rating required for the target application environment.

Gate Driver Selection Notes

Select this component when high-speed switching with matched channel delays is required for dual low-side configurations. It is suitable for designs needing 5A drive strength and operation at elevated junction temperatures up to 140°C. Consider parallel channel usage if higher peak current is necessary beyond the standard 5A specification.

Gate Driver Part Context
