Si822x/3x Isolated Driver Family Block Diagram

The Si822x/3x isolated driver family combines an isolator and two independent drivers into a single package. The Si8230/1/3/4 are high-side/low-side drivers, and the Si8232/5 ICs are dual drivers. The Si8220/1 are opto-input single-channel driver ICs.

Based on Silicon Labs’ proprietary silicon isolation technology, ISOdrivers offer ultra-fast 50 ns propagation delays for better timing margins, rock-solid operation over temperature and time and unparalleled size and cost benefits. ISOdrivers are safety certified to 5.0, 3.75 or 2.5 kVrms and withstand ±1500 VDC between outputs for dual drivers. Driver outputs can be grounded to the same or separate grounds or connected to a positive or negative voltage. The TTL level compatible inputs are available in individual control input (Si8230/2/3/5/6) or PWM input (Si8231/4) configurations. All drivers operate with a maximum supply voltage of 24 V.

When to Use a Digital Isolator vs. an Optocoupler

Over the last four decades, optocouplers have been the "default" signal isolation device, but recent breakthroughs in silicon isolation technology have spawned smaller, faster, and more reliable and cost-effective solutions that have already begun supplanting optocouplers in many end applications. This white paper discusses industrial isolation issues and ways RF isolation technology can be applied to increase system robustness and performance.

Enhancing Power Delivery System Designs with CMOS-Based Isolated Gate Drivers

As emerging green standards challenge designers to deliver more energy-efficient, cost-effective and reliable power delivery systems in smaller form factors, the need for greater power and isolation device integration becomes increasingly important. A critical building block within ac-dc and isolated dc-dc power supplies is the isolated gate driver. While optocoupler-based solutions and gate-drive transformers have been the mainstay for switch-mode power supply (SMPS) systems for many years, fully-integrated isolated gate driver products based on RF technology and implemented in mainstream CMOS provide a more reliable and power-efficient solution.
