Overview
The UCC23313-Q1 is an opto-compatible, single-channel isolated gate driver designed by Texas Instruments. It is specifically tailored for driving IGBTs, MOSFETs, and SiC MOSFETs with high performance and reliability. This component features a 4.5-A source and 5.3-A sink peak output current, along with a 3.75-kV RMS basic isolation rating. The UCC23313-Q1 is AEC-Q100 qualified, making it ideal for automotive applications such as traction inverters, on-board chargers, DC charging stations, and automotive HVAC and heating systems. Its high supply voltage range of up to 33 V allows the use of bipolar supplies to effectively drive power FETs, and it maintains pin-to-pin compatibility with standard opto-isolated gate drivers.
