Overview
The UCC23313BDWYR from Texas Instruments is a single-channel, isolated gate driver designed to drive IGBTs, MOSFETs, and SiC MOSFETs. It features an opto-compatible input stage, making it a pin-to-pin, drop-in upgrade for standard opto-isolated gate drivers. The device boasts a high supply voltage range of up to 33 V, allowing it to effectively drive bipolar supplies for IGBTs and SiC power FETs. It is capable of driving both low-side and high-side power FETs with peak output currents of 4.5 A (source) and 5.3 A (sink).
