Overview
The UCC21739QDWQ1 is an automotive-grade, single-channel isolated gate driver designed for silicon carbide (SiC) MOSFETs and IGBTs. It features a 3 kVrms isolation rating and delivers ±10 A peak drive current. The device operates within a junction temperature range of -40°C to +150°C and supports supply voltages from 3 V to 5.5 V. Key electrical parameters include a maximum propagation delay of 130 ns, with rise and fall times of 33 ns and 27 ns, respectively. It is housed in a 16-pin SOIC package.
Feature Summary
- Provides galvanic isolation for high-voltage power switching applications
- Supports active short-circuit protection and shunt current sensing
- Optimized for fast switching speeds in SiC and IGBT modules
Applications
- Silicon Carbide (SiC) MOSFET gate driving
- Insulated Gate Bipolar Transistor (IGBT) control
- Automotive power electronics systems
Procurement Notes
Verify the specific suffix Q1 confirms AEC-Q100 automotive qualification status against the official Texas Instruments datasheet. Confirm the SOIC-16 package dimensions and thermal characteristics match your PCB layout requirements. Ensure input logic levels are compatible with your controller output before integration.
Selection Notes
Select this component when high dv/dt immunity and robust fault protection are required for wide-bandgap semiconductors. The integrated active short-circuit feature reduces external component count compared to standard drivers. Consider the 150°C operating limit for high-temperature environments where standard 125°C devices may fail.
Part Context
This part belongs to the UCC2173x-Q1 family of isolated gate drivers. It shares architectural similarities with other members like the UCC21736 and UCC21737 but offers specific insulation ratings and protection configurations tailored for demanding automotive power conversion topologies.
Replacement Considerations
Direct substitutes within the same family include UCC21736QDWRQ1 and UCC21737QDWRQ1. Verify that pinouts and isolation voltage ratings are identical before swapping. Note that some variants may have different shutdown or enable configurations.
