2 Rev. 0.2 This architecture provides numerous advantages over opto-drivers: Pin and Package Drop-In Opto-Coupler Upgrade Faster propagation time and better parametric stability over voltage and temperature compared to opto- drivers. Standard CMOS Process Technology CMOS is a well-understood process technology with 40+ years of development and offers 5.5 times lower FIT rate (failures-in-time) than legacy opto-drivers as well as an expanded operating temperature range of –40 to +125 °C (compared to –40 to +85 °C for opto-drivers). The Si826x isolation barrier lifetime is 10 times higher than that of opto-drivers. Part-to-part matching is 14 times tighter than the Gallium Arsenide (GaAs) process technologies used by opto-drivers. Precise Current Thresholds with Hysteresis The Si826x output is either low or high, with none of the ambiguous output states found in opto-drivers, and excellent threshold stability over voltage and temperature. Improved Performance Faster and more precise timing, lower-power operation, higher reliability, reduced internal parasitic coupling for better CMTI, and greater parametric stability over temperature than opto-drivers. Silicon Dioxide Based Capacitive Isolation Barrier Silicon dioxide is an ultra-stable material enabling an unparalleled lifetime of over 60 years, compared to less than 15 years for the mold compound and polyimide tape used in opto-drivers. Superior Surge Tolerance Withstands 10 kV surge per IEC 60065. Wide Product Range The Si826x digital isolators are available in SOIC-8, DIP8, LGA8, and SDIP6 packages. (For more information, see the Si826x isolated driver data sheet.)

Rev. 0.2 5 5. Summary The Si826x isolated gate driver upgrad e is the first and only enhanced opto -driver replacement technology. This device family offers higher perfo rmance and grea ter reliability and ease-of-use t han legacy opto-drivers. The Si826x easily retrofits into existing opto-driver sites and requires no PCB changes. These devices are ideal for retrofit or new designs.
