UCC21220AD

Overview

The UCC21220AD is a dual-channel isolated gate driver from Texas Instruments, designed for high-performance power conversion applications. It features a wide supply voltage range of 3.75 V to 26 V for both channels and supports peak output currents of up to 4 A source and 8 A sink. The device provides robust isolation with a reinforced isolation rating of 5000 Vrms and a common mode transient immunity (CMTI) of 150 kV/µs. It operates within an extended industrial temperature range of -40°C to +125°C and is available in a compact SOIC-16 package.

Feature Summary

Dual-channel architecture enabling independent control of high-side and low-side switches
High common-mode transient immunity ensuring reliable operation in noisy environments
Wide operating supply voltage range compatible with various logic families
Integrated bootstrap diode option for simplified high-side drive circuitry

Applications

Industrial motor drives and inverters
Solar micro-inverters and string inverters
Uninterruptible power supplies (UPS)
Switched-mode power supplies (SMPS)

Procurement Notes

Verify the specific suffix 'AD' indicates the tape and reel packaging variant when ordering. Confirm that the required isolation voltage ratings align with your system's safety standards. Ensure the PCB footprint matches the SOIC-16 package dimensions specified in the mechanical drawings. Check for any regional compliance certifications required for your target market before finalizing procurement.

Selection Notes

Select this component when dual-channel isolation is required with high CMTI specifications. Consider the UCC21220AD over single-channel drivers if space efficiency and channel matching are priorities. Evaluate the 4A/8A current drive capability against the gate charge requirements of the target MOSFETs or IGBTs. Ensure the 150 kV/µs CMTI meets the dv/dt stress conditions of the application.

Part Context

The UCC21220AD belongs to Texas Instruments' UCC21xxx family of isolated gate drivers. This series is engineered for demanding power electronics applications requiring galvanic isolation between control logic and power switches. The AD suffix typically denotes a specific packaging configuration within the broader product line, distinguishing it from other variants like the UCC21220AQ for automotive qualification.
