Description for the UCC23514

The UCC23514 is an Opto-compatible, single-channel,isolated gate driver for IGBTs, MOSFETs and SiC MOSFETs, with 4.5-A source and 5.3-A sink peakoutput current and 5.0-kVRMS reinforced isolation rating. The high supplyvoltage range of 33-V allows the use of bipolar supplies to effectively drive IGBTs and SiC powerFETs. UCC23514 can drive both low side and high side power FETs. Key features and characteristicsbring significant performance and reliability upgrades over standard opto-coupler based gatedrivers while maintaining pin-to-pin compatibility in both schematic and layout design. Performancehighlights include high common mode transient immunity (CMTI), low propagation delay, and smallpulse width distortion.

Tight process control results in small part-to-part skew. The input stage is an emulateddiode (e-diode) which means long term reliability and excellent aging characteristics compared totraditional LEDs. It is offered in an 8-Pin surface mount 7.5 mm x 5.85 mm (typical) SOIC package,with creepage and clearance ≥ 8.5 mm, and a mold compound from material group I which has acomparative tracking index (CTI) > 600 V. UCC23514’s high performance andreliability makes it ideal for use in all types of motor drives, solar inverters, industrial powersupplies, and appliances. The higher operating temperature opens up opportunities for applicationsnot previously able to be supported by traditional opto-couplers.

The UCC23514V option provides the gate drive output on a single terminal. Forapplications requiring split gate drive output, the UCC23514S version provides two separate outputpins, OUTH and OUTL. The UCC23514E version suits applications requiring an UVLO referenced to aseparate COM pin, which facilitates bipolar gate drive supply applications. The UCC23514M optionconnects the gate of the transistor to an internal clamp to prevent false turn-on caused by Millercurrent.
