The UCC21520QDWRQ1 is an automotive-grade, isolated dual-channel gate driver IC from Texas Instruments, engineered to drive power MOSFETs, IGBTs, and SiC MOSFETs at switching frequencies up to 5MHz. Delivering 4A peak source and 6A peak sink current, the device features a 5.7kVRMS reinforced isolation barrier between the input and output sides with greater than 125V/ns common-mode transient immunity (CMTI), plus internal functional isolation between the two secondary-side drivers supporting working voltages up to 1500VDC. Packaged in a 16-pin SOIC (DW) with AEC-Q100 Grade 1 qualification and functional safety quality-managed documentation, this isolated gate driver targets HEV/EV power electronics, motor drives, and industrial power supplies requiring high efficiency, high power density, and robustness.
Applications
● HEV/EV traction inverters and onboard chargers (OBC).
● Motor drives and industrial inverters in servo and robotics systems.
● Solar inverters and energy storage power conversion stages.
● Switched-mode power supplies (SMPS) and DC-DC converters requiring isolated gate drive.
FAQs
Q: What is the CMTI rating? A: The UCC21520-Q1 delivers common-mode transient immunity greater than 125V/ns, ensuring reliable operation in high dV/dt SiC environments.
Q: What UVLO options are available? A: The driver offers 5V and 8V VDD UVLO thresholds, selectable by part number to match IGBT or SiC gate voltage requirements.
