SI8284 - 4.0 Amp ISODrivers

Download the SI8284 datasheet PDF. This datasheet also covers the SI8281 variant, as both devices belong to the same 4.0 amp isodrivers family and are provided as variant models within a single manufacturer datasheet.

Description

The operation of an Si828x channel is analogous to that of an optocoupler and gate driver, except an RF carrier is modulated instead of light.

This simple architecture provides a robust isolated data path and requires no special considerations or initialization at start-up.

Si8281/82/83/84 Data Sheet 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.
