UCC21739QDWRQ1

Overview

The UCC21739QDWRQ1 is a single-channel automotive-grade isolated gate driver manufactured by Texas Instruments. It utilizes capacitive coupling technology to provide galvanic isolation with a rated insulation voltage of 3 kVrms. The device delivers a peak output current of +/-10 A, supporting high-speed switching for power semiconductors. Key electrical parameters include a maximum propagation delay of 130 ns, a rise time of 28 ns, and a fall time of 24 ns. It operates within a supply voltage range of 3 V to 5.5 V and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

Capacitive coupling architecture provides robust galvanic isolation for noise immunity
Automotive qualification ensures reliability in demanding vehicle environments
High peak drive current capability supports fast switching of power devices

Applications

Electric vehicle traction inverters
On-board charger (OBC) systems
DC-DC converter modules

Procurement Notes

Verify the complete part number including the Q suffix to confirm automotive grade status. Ensure the SOIC-16 package variant matches the PCB footprint requirements. Confirm that the specific revision level meets the design specifications for electromagnetic compatibility and thermal management in the target application environment.

Selection Notes

Select this component when a single-channel driver with 3 kVrms isolation is required. The 10 A output current is suitable for driving IGBTs or SiC MOSFETs in medium-power applications. Consider the 130 ns propagation delay for timing constraints. Compare against higher isolation variants if system safety requirements exceed 3 kVrms.

Part Context

This device belongs to the UCC217xx-Q1 family of isolated gate drivers. These components are designed to replace traditional optocouplers in automotive power electronics. The family offers improved performance metrics regarding speed and reliability while maintaining compact form factors suitable for modern electric vehicle powertrains.
