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.
