4.0 Amp ISODrivers with Integrated DC-DC Converters
The Si828x family (Si8281/82/83/84) is made up of isolated, high-current gate drivers
with integrated system safety and feedback functions. These devices are ideal for driving
power MOSFETs and IGBTs used in a wide variety of inverter and motor control applications.
The Si828x isolated gate drivers utilize Silicon Labs' proprietary silicon isolation
technology, supporting up to 5.0 kVrms withstand voltage per UL1577. This technology
enables higher-performance, reduced variation with temperature and age, tighter part-topart
matching, and superior common-mode rejection compared to other isolated gate
driver technologies.
