UCC5350SBD

Overview

The UCC5350SBD is a single-channel, galvanically isolated gate driver from the UCC53x0 family. It features a 3-kVRMS isolation rating and provides 5-A peak output current for driving power switches. The device supports supply voltages from 9.5 V to 33 V on the output side and operates within a temperature range of -40°C to +125°C. Key electrical parameters include a maximum propagation delay of 100 ns, rise/fall times of 10 ns, and a quiescent current of 1.67 mA. It is housed in an SOIC-8 package.

Feature Summary

• Provides high-voltage galvanic isolation with a 3-kVRMS rating for safe signal transmission between low-voltage control and high-voltage power stages.
• Delivers strong 5-A peak drive current capability to ensure fast switching of power devices such as MOSFETs, IGBTs, SiC, and GaN FETs.
• Utilizes capacitive coupling technology to achieve high common-mode transient immunity and reliable operation in electrically noisy environments.

Applications

• Driving Silicon Carbide (SiC) and Gallium Nitride (GaN) field-effect transistors in high-frequency power converters
• Industrial motor drives requiring robust isolation between control logic and power switches
• Isolated DC-DC converter topologies needing precise gate control

Procurement Notes

Verify the specific suffix 'SBD' against the manufacturer's official documentation to confirm pinout configuration and isolation specifications. Ensure compatibility with the target PCB footprint and thermal management requirements. Confirm that the selected component meets all necessary safety certifications for the intended application environment.

Selection Notes

Select this component when a single-channel driver with 3-kVRMS isolation and 5-A output current is required. It is suitable for applications demanding high common-mode transient immunity and fast switching speeds. Consider the SOIC-8 package constraints and operating temperature range relative to the system design.
