The UCC23513 is an Opto compatible, singlechannel,isolated IGBT, SiC, and MOSFET gatedriver with 3-A peak output current and 5KVRMSreinforced isolation rating. The high supply voltagerange of 33 V allows the use of bipolar supplies toeffectively drive SiC power FETs. UCC23513 candrive both high side (with external boot strap diodeand capacitor) and low side power FETs. Keyfeatures and characteristics bring significant　performance 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 means small part-to-part skew. The inputstage is an emulated diode (ediode) which meanslong term reliability and excellent agingcharacteristics over traditional LEDs. In addition, theMaterial Group I mold compound and resultingcomparative tracking index (CTI) of >600 V meansrobust insulating material. UCC23513’s highperformance and reliability along with its stretched　SO-6 package,>8.5-mm clearance and creepagemakes it suitable for inverter applications in motordrive and solar, DC motor control, industrial powersupplies, and appliances. The higher operatingtemperature opens up opp...
