Si8261BCC-IS 

The Si8261BCC-IS ISOdrivers are pin-compatible, drop-in upgrades for popular gate drive optocouplers. The devices are ideal for driving power MOSFETs and IGBTs used in a wide variety of inverter and motor control applications. The Si8261BCC-IS isolated gate drivers utilize Silicon Labs' proprietary silicon isolation technology, supporting up to 3.75 kV RMS withstand voltage per UL1577. This technology enables higher-performance, reduced variation with temperature and age, tighter part-to-part matching and superior common-mode rejection compared to opto-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 Si8261BCC-IS series offers longer service life and dramatically higher reliability compared to optocoupled gate drivers. Package options include the SO8, DIP8, LGA8 and SDIP6.
