UCC5390SCDR

Overview

The UCC5390SCDR is a single-channel current-isolated gate driver from Texas Instruments, housed in an SOIC-8 package. It provides galvanic isolation with a 3-kVRMS rating and delivers 10 A peak output current for both sourcing and sinking. The device operates within a supply voltage range of 3 V to 15 V on the input side and supports output voltages from 13.2 V to 33 V. Key electrical parameters include a maximum propagation delay of 100 ns, rise and fall times of 10 ns, and a quiescent supply current of 1.67 mA. It functions across a temperature range of -40°C to +125°C.

Feature Summary

• Provides high-speed signal transmission through capacitive coupling technology
• Delivers robust 10 A drive capability for efficient power switch control
• Ensures safety via 3-kVRMS reinforced insulation barrier
• Supports both inverting and non-inverting logic configurations

Applications

• Industrial motor drives requiring isolated switching
• Inverter circuits in renewable energy systems
• High-frequency power conversion topologies
• Automotive power electronics interfaces

Procurement Notes

Verify the specific suffix 'CDR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the SOIC-8 footprint matches the target PCB design guidelines. Ensure compliance with RoHS directives as indicated in manufacturer specifications before finalizing procurement orders.

Selection Notes

Select this component when a single-channel solution with high peak current drive is necessary. The 3-kVRMS isolation rating suits applications demanding significant potential differences between control and power domains. Consider the 100 ns propagation delay for timing-sensitive designs where moderate speed is acceptable.

Part Context

This part belongs to the UCC5390 series of single-channel isolated gate drivers. It utilizes Texas Instruments' iCoupler technology for signal transmission without magnetic components. The series is designed to replace traditional optocouplers in modern power management applications requiring higher reliability and faster switching speeds.

Replacement Considerations

Consult official substitution guides for compatible alternatives within the same isolation class. Verify pinout compatibility if replacing legacy optocoupler-based designs directly.
