UCC5350MCDR

Overview

The UCC5350MCDR is a single-channel, galvanically isolated gate driver manufactured by Texas Instruments. It utilizes capacitive coupling technology to provide signal isolation with a rated voltage of 3-kVRMS. The device features a peak output current capability of 5 A for both sourcing and sinking. It operates within a supply voltage range of 3 V to 15 V on the input side and supports output drive voltages from 13.2 V to 33 V. Key timing parameters include a maximum propagation delay of 65 ns, rise and fall times of 10 ns, and a maximum pulse width distortion of 20 ns. The component is housed in an 8-SOIC package and functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Provides high-speed signal transmission via capacitive coupling isolation technology.
• Delivers robust common-mode transient immunity to ensure reliable operation in noisy environments.
• Supports flexible logic configurations including both inverting and non-inverting modes.

Applications

• Driving MOSFETs and IGBTs in industrial motor drives
• Power conversion systems requiring galvanic isolation
• Inverter circuits in renewable energy applications

Procurement Notes

Verify the specific suffix 'DR' indicates tape-and-reel packaging when ordering. Confirm that the 3-kVRMS isolation rating meets the safety requirements of the target application. Ensure compatibility with the required SOIC-8 footprint during PCB layout. Check for RoHS compliance status if environmental regulations apply to the manufacturing process.

Selection Notes

Select this component when a single-channel isolated driver with 5 A peak current is required. Consider the 3-kVRMS isolation barrier for applications needing significant voltage separation between control and power stages. Evaluate the 65 ns propagation delay against switching frequency requirements. Compare against other UCC53x0 variants if different current ratings or isolation voltages are needed.

Part Context

This part belongs to the UCC53x0 family of single-channel isolated gate drivers from Texas Instruments. The family shares similar capacitive coupling architecture but varies in current drive capabilities and isolation ratings. The UCC5350 specifically targets applications requiring moderate peak current with standard isolation levels, distinguishing it from higher-current or higher-voltage variants within the same series.

Replacement Considerations

Public confirmed substitute part numbers: UCC5350-MQDQRQ1 (Automotive grade variant). Verify pinout and electrical specifications match before substitution.
