The Silicon Labs Si826x family of digital drivers is an industry-first provider of a digital CMOS drop-in replacement solution for opto-coupled drivers (or opto-drivers). The Si826x drivers offer an ideal configuration, package, and footprint fit for a number of opto-driver products used in industrial drives and motor control, solar power inverters, switched mode power supplies (SMPS), uninterruptible power supplies (UPS), and high-voltage medical equipment. The Si826x devices provide superior common-mode transient immunity (CMTI), more robust performance, and greater reliability than opto-drivers, making them ideal solutions for applications such as high-power motor control that require long-term performance and longer product warranties (up to 20 years of fail-safe operation).
The Si826x family has key performance advantages over competing opto-drivers, while providing industry-leading isolation levels. The minimum CMTI specification for the Si826xB device is approximately 75% higher than competing opto-drivers. The Si826xA device uses about one-half the input turn-on current required by a similar opto-driver. All Si826x drivers have improved pulse-width distortion and propagation delay compared to competing opto-driver products.
Silicon Labs' Si871x family of digital isolators provides a drop-in replacement solution for optocouplers. The Si871x devices provide superior noise immunity, more robust performance, and greater reliability than optocouplers. They are also the first optocoupler replacements based on mainstream CMOS technology and incorporating an innovative LED emulator front-end.
The Si871x isolators offer ideal configurations, packages, and footprints to replace a wide range of optocoupler products used in solar power inverters, switched mode power supplies (SMPS), uninterruptible power supplies (UPS), industrial drives, programmable logic controllers (PLC), and high-voltage medical equipment.
