UCC21759QDWQ1

Overview

The UCC21759QDWQ1 is an automotive-grade, single-channel isolated gate driver from Texas Instruments. It provides 3.0kVrms basic isolation and delivers a peak output current of +/-10A. The device operates within a supply voltage range of 3V to 5.5V on the input side and supports output voltages up to 33V. Key electrical parameters include a maximum propagation delay of 130ns, a rise time of 33ns, and a fall time of 27ns. It features both inverting and non-inverting configurations and is housed in a 16-pin SOIC package with an operating temperature range of -40°C to +150°C.

Feature Summary

• Provides galvanic isolation for safe control of high-voltage power switches
• Capable of driving SiC and IGBT devices with high peak current
• Supports flexible logic input configurations

Applications

• Automotive traction inverters
• On-board chargers (OBC)
• DC-DC converters

Procurement Notes

Verify the specific suffix 'DWQ1' to confirm the SOIC-16 tube packaging and automotive qualification grade. Confirm that the component meets AEC-Q100 Grade 1 requirements for your target environment. Check for end-of-life notifications as some variants in this family may have discontinuance statuses. Ensure design compatibility with the required isolation voltage standards for your application.

Selection Notes

Select this component when a single-channel driver with 3.0kVrms isolation is sufficient. Compare against the UCC21750QDWQ1 if higher 5.7kVrms isolation is required. Consider the UCC21739QDWRQ1 if active short-circuit protection or shutdown functionality is needed. Evaluate thermal dissipation capabilities given the 985mW power dissipation rating in the SOIC-16 package.

Part Context

This part belongs to the UCC2175x series of isolated gate drivers designed for automotive power electronics. It utilizes capacitive coupling technology to achieve signal transmission across the isolation barrier. The Q1 suffix indicates compliance with automotive reliability standards, making it suitable for critical vehicle systems requiring robust performance under varying thermal conditions.

Replacement Considerations

UCC21759QDWRQ1 offers the same electrical specifications but in a tape-and-reel package format.
