Overview
The UCC21331CQDRQ1 is an automotive-grade, isolated dual-channel gate driver from Texas Instruments. It features a 3kVRMS capacitive isolation barrier and supports peak output currents of 4A source and 6A sink. The device operates within a supply voltage range of 13.5V to 25V and includes programmable dead time control. It utilizes SOIC-16 packaging and complies with AEC-Q100 standards for temperatures ranging from -40°C to +125°C.
Feature Summary
- Provides galvanic isolation via a robust capacitive coupling barrier rated at 3kVRMS.
- Integrates programmable dead-time functionality to prevent shoot-through in half-bridge configurations.
- Delivers high peak drive current capability suitable for fast-switching power devices.
Applications
- Automotive traction inverters
- On-board chargers (OBC)
- DC-DC converters
Procurement Notes
Verify the specific suffix 'CQDRQ1' against the official Texas Instruments datasheet to confirm package type, temperature grade, and automotive qualification status. Ensure compatibility with system isolation requirements and input logic levels before procurement.
Selection Notes
Select this component when designing isolated gate drive circuits requiring precise dead-time management and high reliability in automotive environments. Compare propagation delay specifications and isolation voltage ratings against alternative drivers to ensure adequate noise immunity and switching speed for the target application.
Part Context
This part belongs to the UCC2133x-Q1 family of isolated gate drivers. It shares architectural similarities with the UCC21330 but adds programmable dead-time capabilities. It is distinct from non-automotive variants and differentiates itself from other TI drivers by its specific combination of current drive and isolation rating.
Replacement Considerations
The UCC21330CQDRQ1 is a related variant within the same family but lacks programmable dead time. Verify functional equivalence regarding isolation voltage and drive current if substituting.
