1 / 40 page  Rev. 1.3 5/15 Copyright © 2015 by Silicon Laboratories Si826x Si826x 5 KV LED E MULATOR I NPUT, 4.0 A I SOLATED G ATE D RIVERS Features Applications Safety Regulatory Approvals Description The Si826x isolators are pin-compatible, drop-in upgrades for popular opto- coupled gate drivers, such as 0.6 A ACPL-0302/3020, 2.5 A HCPL-3120/ACPL- 3130, HCNW3120/3130, and similar opto-drivers. The devices are ideal for driving power MOSFETs and IGBTs used in a wide variety of inverter and motor control applications. The Si826x isolated gate drivers utilize Silicon Laboratories' proprietary silicon isolation technology, supporting up to 5.0 kVRMS withstand voltage per UL1577 and 10kV surge protection per IEC60747. This technology enables higher-performance, reduced variation with temperature and age, tighter part-to-part matching, and superior common-mode rejection compared to opto- coupled gate drivers. While the input circuit mimics the characteristics of an LED, less drive current is required, resulting in higher efficiency. Propagation delay time is independent of input drive current, resulting in consistently short propagation times, tighter unit-to-unit variation, and greater input circuit design flexibility. As a result, the Si826x series offers longer service life and dramatically higher reliability compared to opto-coupled gate drivers. Pin-compatible, drop-in upgrades for popular high speed opto-coupled gate drivers Low power diode emulator simplifies design-in process 0.6 and 4.0 Amp peak output drive current Rail-to-rail output voltage Performance and reliability advantages vs. opto-drivers Resistant to temperature and age 10x lower FIT rate for longer service life 14x tighter part-to-part matching Higher common-mode transient immunity: >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: 6.5 to 30 V Up to 5000 VRMS isolation 10 kV surge withstand capability 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 renewable energy inverters AC, Brushless, and DC motor controls and drives Variable speed motor control in consumer white goods Isolated switch mode and UPS power 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/VDE0884-10 (basic/reinforced insulation) CQC certification approval GB4943.1 Patent pending Pin Assignments: See page 22 1 2 3 4 8 7 6 5 ANODE CATHODE NC VDD VO VO SOIC-8, DIP8, LGA8 Industry Standard Pinout GND UVLO 1 3 6 5 4 ANODE CATHODE VDD VO GND SDIP6 Industry Standard Pinout 2 NC UVLO e e |
