UCC5350MCD

Overview

The UCC5350MCD is a single-channel galvanically isolated gate driver from Texas Instruments, housed in an 8-SOIC package. It provides 3-kVRMS isolation and supports both inverting and non-inverting configurations. The device delivers a typical peak output current of 5A source and 5A sink. It operates within a supply voltage range of 3V to 15V on the input side and 13.2V to 33V on the output side. Key electrical parameters include a maximum propagation delay of 65ns, rise/fall times of 10ns, and a minimum common-mode transient immunity of 100kV/µs. It functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Provides high-speed signal transmission with low propagation delay and fast rise/fall times for efficient switching control.
• Features robust galvanic isolation capability to protect low-voltage control circuits from high-voltage power stages.
• Supports flexible logic configuration with selectable inverting or non-inverting output modes.

Applications

• Driving MOSFETs and IGBTs in industrial motor drives
• Power conversion systems requiring isolated gate control
• Inverter topologies in renewable energy applications

Procurement Notes

Verify the specific suffix 'CD' indicates the SOIC-8 package variant when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure design compatibility with required isolation voltage ratings and operating temperature ranges specified in the datasheet.

Selection Notes

Select this component for applications requiring single-channel isolation with moderate peak drive current. Compare against other UCC535x variants if higher current (10A) or different packaging options are needed. Validate that the 3-kVRMS isolation rating meets system safety requirements.

Part Context

This part belongs to the UCC5350 series of isolated gate drivers designed for basic or reinforced isolation applications. It complements other devices in the family such as the UCC5350-Q1 for automotive use or variants with different output currents.

Replacement Considerations

Check for direct pin-compatible substitutes within the UCC535x family. Verify functional equivalence regarding isolation voltage and drive strength before substitution.

FAQ
