UCC23514 Gate Driver

Texas Instruments UCC23514 Gate Driver is an opto-compatible, single-channel, isolated gate driver for IGBTs, MOSFETs, and SiC MOSFETs. It comes with a 4.5A source and 5.3A sink peak output current, and a 5.0kV_RMS reinforced isolation rating. The high supply voltage range of 33V allows the use of bipolar supplies to effectively drive IGBTs and SiC power FETs. UCC23514 can drive both low side and high side power FETs. Key features and characteristics bring significant performance and reliability upgrades over standard optocoupler based gate drivers while maintaining pin-to-pin compatibility in both schematic and layout design. Performance highlights include high common-mode transient immunity (CMTI), low propagation delay, and small pulse width distortion.
