Overview
The UCC5350SBQDRQ1 is an automotive-grade, single-channel isolated gate driver designed for high-speed switching applications. It features a typical peak source and sink current of 5A, supporting robust drive capabilities for power switches. The device utilizes capacitive coupling technology to provide galvanic isolation with a rated isolation voltage of 3kVRMS. Key electrical parameters include a maximum propagation delay of 65ns, rise and fall times of 10ns each, and a minimum common-mode transient immunity of 100kV/µs. It operates within a supply voltage range of 9.5V to 33V on the output side and functions reliably across a temperature range of -40°C to 125°C.
Feature Summary
- Capacitive coupling technology ensures high-speed signal transmission with superior common-mode transient immunity.
Applications
- Automotive motor control systems
- Inverter bridge driving in electric vehicles
- High-voltage DC-DC converter isolation stages
Procurement Notes
Verify that the specific part number suffix matches the required package width and isolation rating. Confirm AEC-Q100 Grade 1 qualification status if automotive reliability is mandatory. Ensure the procurement channel provides valid RoHS compliance documentation. Cross-reference the datasheet revision to confirm compatibility with existing design specifications.
Selection Notes
Select this component when a single-channel driver with 5A peak current capability is required for automotive environments. It is suitable for applications demanding high common-mode noise rejection and fast switching speeds. Consider the SOIC-8 package dimensions for PCB layout constraints. Verify that the input logic levels are compatible with the controlling microcontroller or DSP.
Part Context
This component belongs to the UCC53x0 family of isolated gate drivers from Texas Instruments. The family includes variants with different isolation ratings and package options, such as the standard UCC5350 and the wider-body UCC5350DWV. The SBQDRQ1 designation indicates the automotive qualification, specific package type, and tape-and-reel packaging format.
Replacement Considerations
Direct substitutes within the same family include the UCC5350MCDR for non-automotive applications or the UCC5350-Q1 for alternative package configurations. Verify pinout compatibility and thermal performance before swapping. Check if the replacement meets the specific 3kVRMS isolation requirement.
