UCC23313

4A 3KVrms Isolated Gate Driver

描述

The UCC23313 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 peak output current and 3.75-kVRMS basic isolation rating. The high supply voltage range of 33 V allows the use of bipolar supplies to effectively drive IGBTs and SiC power FETs. UCC23313 can drive both low side and high 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 results in small part-to-part skew. The input stage is an emulated diode (ediode) which means long term reliability and excellent aging characteristics compared to traditional LEDs. It is offered in a stretched SO6 package with >8.5-mm creepage and clearance, and a mold compound from material group I which has a comparative tracking index (CTI) >600 V. UCC23313’s high performance and reliability makes it ideal for use in all types of motor drives, solar inverters, industrial power supplies, and appliances. The higher operating temperature opens up opportunities for applications not previously able to be supported by traditional optocouplers.
