UCC5320SCDWVR

Overview

The UCC5320SCDWVR is a single-channel current-isolated gate driver from Texas Instruments, housed in an SOIC-8 package. It provides galvanic isolation with a 3kVrms basic and 5kVrms reinforced rating. The device delivers a peak output current of 2.4 A and operates within a supply voltage range of 13.2 V to 33 V. Key electrical characteristics include a maximum propagation delay of 75 ns, a rise time of 12 ns, and a fall time of 10 ns. It supports both inverting and non-inverting configurations without a shutdown function. The component functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Utilizes capacitive coupling technology for high-speed signal transmission with robust common-mode transient immunity.
• Provides enhanced safety isolation ratings suitable for demanding industrial and power conversion environments.
• Features a compact eight-pin surface-mount package designed for efficient PCB layout integration.

Applications

• Industrial motor drives
• Solar inverters
• Uninterruptible power supplies (UPS)
• High-frequency DC-DC converters

Procurement Notes

Verify the complete part number against official Texas Instruments documentation to ensure correct suffix alignment. Confirm that the specific orderable part matches the required isolation rating and package variant. Cross-reference the manufacturer's latest datasheet for any updates regarding moisture sensitivity levels or recommended soldering profiles prior to procurement.

Selection Notes

Select this component when a single-channel isolated driver with high peak current capability is required. Ensure the application demands a wide input supply voltage range up to 33 V. Verify that the system architecture accommodates the absence of a dedicated shutdown pin. Confirm that the thermal dissipation requirements align with the specified power dissipation limits under expected operating conditions.

Part Context

This device belongs to the UCC53x0 family of single-channel isolated gate drivers. It shares architectural similarities with other members like the UCC5350 but differs in specific isolation ratings and current drive capabilities. The series is designed to replace traditional optocouplers in applications requiring higher speed and reliability.

Replacement Considerations

Consult official substitution guides for compatible alternatives such as the UCC5350SCDR. Verify that any substitute maintains equivalent isolation voltages and package dimensions to ensure mechanical compatibility.
