Skyworks Solutions Inc. Si826x Digital Drivers
Skyworks Solutions Inc. Si826x Digital Drivers provide a digital CMOS drop-in replacement solution for optocoupler drivers (or opto-drivers). The Si826x drivers offer an ideal configuration, package, and footprint fit for a number of opto-driver products that are used in industrial drives and motor control, solar power inverters, switched-mode power supplies (SMPS), uninterruptible power supplies (UPS), and high-voltage medical equipment. Si826x devices provide superior common-mode transient immunity, more robust performance, and greater reliability than opto-drivers. This makes 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).Features
