UCC21540AQDWKRQ1

Overview

The UCC21540AQDWKRQ1 is an automotive-grade, reinforced isolated dual-channel gate driver from Texas Instruments. It features capacitive coupling for signal transmission and operates within a wide temperature range of -40°C to +125°C. The device provides independent high-current drive capabilities with peak output currents of 4A and 6A. It supports supply voltages up to 25V and includes programmable dead time control. Key electrical specifications include a maximum propagation delay of 40ns, rise time of 5ns, and fall time of 6ns. It is housed in a SOIC-14 package and meets AEC-Q100 qualification standards.

Feature Summary

Reinforced isolation capability with 5700VRMS insulation voltage rating
Dual-channel architecture with independent 4A and 6A output drivers
Programmable dead-time control for precise switching management
Capacitive coupling technology ensuring high common-mode transient immunity

Applications

Automotive powertrain systems
Electric vehicle (EV) traction inverters
On-board chargers (OBC)
DC-DC converters in automotive environments

Procurement Notes

Verify the specific suffix 'RQ1' confirms automotive grade and reel packaging configuration. Confirm the 'A' variant designation against current manufacturer lifecycle status, as some sources indicate potential obsolescence for this specific marking. Ensure compatibility with SOIC-14 footprint requirements during procurement planning.

Selection Notes

Select this component when reinforced isolation and programmable dead time are required for automotive applications. Compare against UCC21530 or UCC21520 variants if different isolation ratings or channel configurations are needed. Consider the 5700VRMS rating for safety-critical designs requiring enhanced barrier protection.

Part Context

This part belongs to the UCC21540-Q1 family of isolated gate drivers designed for harsh automotive environments. It utilizes TI's capacitive isolation technology to provide robust performance against electromagnetic interference. The SOIC-14 package allows for compact PCB layout in high-density power modules.
