UCC235134-A/5-A,5.7-kVRMSOpto-CompatibleSingleChannelIsolatedGate Driver The UCC23513 is an Opto-compatible, singlechannel,isolated gate driver for IGBTs, MOSFETsand SiC MOSFETs, with 4.5-A source and 5.3-A sinkpeak output current and 5.7-KVRMS reinforcedisolation rating. The high supply voltage range of 33-V allows the use of bipolar supplies to effectivelydrive IGBTs and SiC power FETs. UCC23513 candrive both low side and high side power FETs. Keyfeatures and characteristics bring significantperformance and reliability upgrades over standardopto-coupler based gate drivers while maintainingpin-to-pin compatibility in both schematic and layoutdesign. Performance highlights include high commonmode transient immunity (CMTI), low propagationdelay, and small pulse width distortion. Tight processcontrol results in small part-to-part skew. The inputstage is an emulated diode (ediode) which meanslong term reliability and excellent agingcharacteristics compared to traditional LEDs. It isoffered in a stretched SO6 package with >8.5mmcreepage ...
