The devices are ideal for drivingpower MOSFETs and IGBTs used in a wide variety of inverter and motor controlapplications. The Si826x isolated gate drivers utilize Silicon Laboratories'proprietary silicon isolation technology, supporting up to 5.0 kVRMS withstandvoltage per UL1577. This technology enables higher-performance, reducedvariation with temperature and age, tighter part-to-part matching, and superiorcommon-mode rejection compared to opto-coupled gate drivers. While the inputcircuit mimics the characteristics of an LED, less drive current is required,resulting in higher efficiency. Propagation delay time is independent of input drivecurrent, resulting in consistently short propagation times, tighter unit-to-unitvariation, and greater input circuit design flexibility. As a result, the Si826x seriesoffers longer service life and dramatically higher reliability compared to opto-coupled gate drivers. Pin-compatible, drop-in upgrades forpopular high speed opto-coupledgate drivers Low power diode emulator simplifiesdesign-in process 0.6 and 4.0 Amp peak output drivecurrent Rail-to-rail output voltage Performance and reliabilityadvantages vs. opto-driversResistant to temperature and age10x lower FIT rate for longerservice life14x tighter part-to-part matchingHigher common-mode transientimmunity: >50 kV/µs typical Robust protection featuresMultiple UVLO ordering options(5, 8, and 12 V) with hysteresis 60 ns propagation delay,independent of input drive current Wide VDD range: 5 to 30 V 3.75 and 5 kV reinforced isolationUL, CSA, VDE AEC-Q100 qualified Wide operating temperature range–40 to 125 °C RoHS-compliant packagesSOIC-8 (Narrow body)DIP8 (Gull-wing)SDIP6 (Stretched SO-6)LGA8 IGBT/ MOSFET gate drives Industrial, HEV and renewableenergy inverters AC, Brushless and DC motorcontrols and drives Variable speed motor control inconsumer white goods Isolated switch mode and UPSpower supplies UL 1577 recognizedUp to 5000 Vrms for 1 minute CSA component notice 5A approvalIEC 60950-1, 61010-1, 60601-1(reinforced insulation) VDE certification conformityIEC60747-5-2/VDE0884 Part 10(basic/reinforced insulation) CQC certification approvalGB4943.1Patent pendingPin Assignments:See page 2412348765ANODECATHODENCVDDVOVOSOIC-8, DIP8, LGA8Industry Standard PinoutGNDUVLO13654ANODECATHODEVDDVOGNDSDIP6Industry Standard Pinout2NCUVLOee
