UCC5320ECDR

Overview

The UCC5320ECDR is a single-channel galvanically isolated gate driver from Texas Instruments, utilizing capacitive coupling technology. It operates within an extended temperature range of -40°C to +125°C and is housed in an 8-SOIC package. The device provides high-speed signal transmission with a maximum propagation delay of 75 ns, featuring rise and fall times of 12 ns and 10 ns respectively. It supports peak output currents up to 4.3 A and delivers continuous drive currents of 2.4 A. The isolation rating is specified at 3 kVrms for basic isolation and 5 kVrms for reinforced isolation. The driver accepts CMOS logic inputs and functions with supply voltages ranging from 13.2 V to 33 V.

Feature Summary

• Capacitive coupling architecture enables high common-mode transient immunity of 100 kV/µs
• Single-channel configuration supports both inverting and non-inverting logic operations
• Galvanic isolation separates control and power domains without magnetic components

Applications

• Industrial motor drives requiring robust isolation
• Inverter systems for renewable energy applications
• High-frequency switching power supplies

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required isolation ratings and package variants. Confirm that the component meets RoHS3 standards and humidity sensitivity level 2 requirements for your assembly process. Cross-reference the part number with official Texas Instruments documentation to validate authenticity and avoid counterfeit risks during sourcing.

Selection Notes

Select this component when a single-channel isolated driver with high CMTI is required. Ensure the application voltage does not exceed the 33 V limit and that the PCB layout accommodates the SOIC-8 footprint. Consider the 75 ns propagation delay for timing-sensitive designs and verify thermal management capabilities for operation up to 125°C.

Part Context

This device belongs to the UCC53x0 series of isolated gate drivers. It complements other models in the family by offering a cost-effective solution for single-channel applications. The series utilizes Texas Instruments' proprietary capacitive isolation technology to provide reliable performance in noisy electrical environments while maintaining compact form factors suitable for modern power electronics.

Replacement Considerations

Consult the UCC5320 datasheet for direct pin-compatible alternatives within the UCC53x0 family. Verify functional equivalence regarding isolation voltage and drive strength before substitution.
