Skyworks SI8261BAC-C-IP

容性耦合13750Vrms

Overview

The Si826x series Isolated Gate Driver ideal for driving power MOSFETs and IGBTs used in a wide variety of inverter and motor control applications. It utilizes Silicon Laboratories' proprietary silicon isolation technology, supporting up to 5kVRMS withstand voltage per UL1577 and 10kV surge protection per IEC60747. This technology enables higher-performance, reduced variation with temperature and age, tighter part-to-part matching and superior common-mode rejection compared to optocoupled gate drivers. While the input circuit mimics the characteristics of an LED, less drive current is required, resulting in higher efficiency. Propagation delay time is independent of input drive current, resulting in consistently short propagation times, tighter unit-to-unit variation and greater input circuit design flexibility. As a result, the Si826x series longer service life and dramatically higher reliability compared to opto-coupled gate drivers.
