UCC23513 (PREVIEW) 3-A, 5-kVRMS opto-compatible single channel isolated gate driver

The UCC23513 is an Opto compatible, single-channel, isolated IGBT, SiC, and MOSFET gate driver with 3-A peak output current and 5KV_RMS reinforced isolation rating. The high supply voltage range of 33 V allows the use of bipolar supplies to effectively drive SiC power FETs. UCC23513 can drive both high side (with external boot strap diode and capacitor) and low side power FETs. Key features and characteristics bring significant performance and reliability upgrades over standard opto-coupler 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. Tight process control means small part-to-part skew. The input stage is an emulated diode (ediode) which means long term reliability and excellent aging characteristics over traditional LEDs. In addition, the Material Group I mold compound and resulting comparative tracking index (CTI) of >600 V means robust insulating material. UCC23513’s high performance and reliability along with its stretched SO-6 package, > 8.5-mm clearance and creepage makes it suitable for inverter applications in motor drive and solar, DC motor control, industrial power supplies, and appliances. The higher operating temperature opens up opportunities for applications not previously able to be supported by traditional optocouplers.
