UCC5350MCQDRQ1

Overview

The UCC5350MCQDRQ1 is an automotive-grade, single-channel isolated gate driver featuring a typical peak output current of 10A source and 10A sink. It utilizes capacitive coupling technology to provide galvanic isolation with a reinforced insulation rating of 5000Vrms. The device operates within a supply voltage range of 3V to 15V for the input side and supports output drive voltages from 13.2V to 33V. Key electrical parameters include a maximum propagation delay of 65ns, rise and fall times of 10ns each, and a minimum common-mode transient immunity (CMTI) of 100kV/µs. It is housed in an 8-SOIC package.

Feature Summary

• Provides reinforced galvanic isolation via capacitive coupling technology for high noise immunity.
• Features integrated Miller clamp functionality to prevent false turn-on during high dv/dt events.
• Supports split-output configuration to optimize switching speed and reduce electromagnetic interference.
• Designed for robust performance in harsh automotive environments with wide operating temperature ranges.

Applications

• Automotive traction inverters and motor drives
• On-board chargers (OBC) and DC-DC converters
• Industrial motor control systems
• High-voltage power supply gate driving

Procurement Notes

Verify that the specific suffix 'MCQDRQ1' corresponds to the automotive qualification and packaging requirements. Confirm the datasheet revision matches the design-in specifications. Ensure compliance with RoHS and REACH directives as stated in the manufacturer's documentation. Check for any recent product change notices regarding assembly sites or marking standardization.

Selection Notes

Select this component when automotive reliability and reinforced isolation are required. The 10A peak current capability suits medium-power MOSFET and IGBT applications. Consider the integrated Miller clamp if driving loads susceptible to parasitic turn-on. Verify that the SOIC-8 package fits the PCB layout constraints and thermal management strategy.

Part Context

This part belongs to the UCC5350-Q1 family of isolated gate drivers from Texas Instruments. It is specifically designed for automotive applications, meeting AEC-Q100 standards. The family includes variants with different current ratings and isolation levels, but this specific model emphasizes high peak current and reinforced isolation for critical power electronics.

Replacement Considerations

Direct substitutes may include other UCC5350-Q1 variants with different suffixes indicating package or temperature variations. Cross-referencing with UCC5350MCDR is possible for non-automotive contexts, but functional equivalence must be verified against isolation ratings and peak current capabilities.
