Isolated Gate Driver SKYWORKS SI8271GBD-IS for Power Supply Inverter and Motor Control Applications

Product Overview

The Si827x isolators are 4 Amp ISOdrivers designed for driving power switches in power supply, inverter, and motor control applications. Utilizing Skyworks' proprietary silicon isolation technology, they offer industry-leading common-mode transient immunity (CMTI), tight timing, reduced variation, and high reliability. Key features include separate pull-up/down outputs, driver shutdown on UVLO fault, and precise dead-time programmability, providing a longer service life and higher reliability compared to opto-coupled drivers. These drivers support up to 2.5 kVRMS withstand voltage per UL1577 and VDE0884, with fast 60 ns propagation times. Available in TTL level compatible inputs with hysteresis, they come in individual control or PWM input configurations. The Si827x family is ideal for isolated MOSFET/IGBT and SiC or GaN FET gate drive applications due to its high integration, low propagation delay, small size, flexibility, and cost-effectiveness. Automotive Grade products are also available, built with automotive-specific manufacturing flows for enhanced robustness.
