Product details

What this gate driver brings to an automotive BOM

The Texas Instruments UCC23511QDWYRQ1 is a single-channel isolated gate driver built around capacitive coupling technology, delivering 5700 Vrms of reinforced isolation in a 6-SOIC package.

Isolation and transient immunity — the numbers that matter for the power stage

The 5700 Vrms isolation voltage covers reinforced insulation requirements for motor-drive and grid-tied inverter designs. Common-mode transient immunity is specified at a minimum 150 kV/µs.

Output drive and supply range

The output supply rail accepts 14 V to 33 V, covering the typical gate-drive bias for standard IGBTs and SiC MOSFETs. Peak output current is rated 1.5 A source and 2 A sink.

Frequently asked questions

Is UCC23511QDWYRQ1 AEC-Q100 qualified?

Yes. The UCC23511QDWYRQ1 carries AEC-Q100 qualification, which is the automotive-grade standard for integrated circuits. The part also holds approvals from CQC, UL, and VDE for safety isolation.

What is the common mode transient immunity of UCC23511QDWYRQ1?

Minimum 150 kV/µs. This level of CMTI ensures the gate driver maintains its output state during the high-speed voltage transitions typical of SiC and GaN switching stages in traction inverters.

Can UCC23511QDWYRQ1 drive IGBTs and SiC MOSFETs?

Yes. With a 1.5 A source and 2 A sink peak output and a 14 V to 33 V supply range, it directly drives IGBTs and SiC MOSFETs in the 600 V–1200 V class. The 150 kV/µs CMTI and matched propagation delays suit hard-switched inverter topologies.

What are the alternatives to UCC23511QDWYRQ1?

The UCC23513QDWYRQ1 is a pin-compatible sibling with a higher 3 A peak output current rating, suitable for driving larger IGBT modules. Both share the same 6-SOIC footprint, 5.7 kVrms isolation, and AEC-Q100 qualification.
