UCC20225AQNPLTQ1

Overview

The UCC20225AQNPLTQ1 is a single-input, dual-channel isolated gate driver designed for high-power density applications. It features a 4A peak source and 6A peak sink current capability, supporting switching frequencies up to 5MHz for power MOSFETs, IGBTs, and SiC MOSFETs. The device utilizes capacitive coupling technology with a 2.5kVRMS reinforced isolation barrier and a minimum common-mode transient immunity (CMTI) of 100V/ns. Internal functional isolation between the two secondary-side drivers allows operation at voltages up to 700VDC. It operates within a temperature range of -40°C to +125°C and is housed in a compact 5mm x 5mm LGA-13 package.

Feature Summary

• Single PWM input controls dual independent output channels for synchronized or phase-shifted driving.
• Capacitive coupling isolation provides robust signal transmission with high CMTI performance.
• Internal isolation between outputs enables floating supply configurations for high-side and low-side control.
• Optimized propagation delay and pulse width distortion support high-frequency switching operations.

Applications

• Driving power MOSFETs and IGBTs in high-density DC-DC converters
• Control circuits for Silicon Carbide (SiC) MOSFETs in electric vehicle inverters
• Isolated gate drive stages in industrial motor drives and traction systems

Procurement Notes

Verify the specific suffix 'A' indicates the enhanced variant specifications compared to the base model. Confirm AEC-Q100 qualification status is required for automotive integration. Check for End-of-Life notices as distribution availability may be limited. Ensure the 13-VLGA package footprint matches the PCB design constraints. Validate insulation ratings against system safety standards before procurement.

Selection Notes

Select this component when high-frequency switching above 1MHz is required alongside strict size constraints. The dual-channel architecture simplifies designs needing isolated half-bridge or full-bridge configurations. Consider the 700VDC internal isolation rating for floating supply applications. Evaluate the 4A/6A current drive strength against the target power device's gate charge requirements. Ensure the 2.5kVRMS isolation voltage meets the system's creepage and clearance regulations.
