SI8261AAC-C-IP Silicon LabAs, 600mA Gate Driver Capacitive Coupling 3750Vrms 1 Channel 8-DIP Gull Wing
The Si826x isolators are pin-compatible, drop-in upgrades for popular optocoupled gate drivers, such as 0.6 A ACPL-0302/3020, 2.5 A HCPL-3120/ACPL- 3130, HCNW3120/3130, and similar opto-drivers. The devices are ideal for driving power MOSFETs and IGBTs used in a wide variety of inverter and motor control applications. The Si826x isolated gate drivers utilize Silicon Laboratories' proprietary silicon isolation technology, supporting up to 5.0 kVRMS 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 offers longer service life and dramatically higher reliability compared to opto-coupled gate drivers.
