Si828x ISOdriver Gate Drivers

Skyworks Solutions' Si828x ISOdriver portfolio is a family of 4 amp isolated gate drivers designed to protect insulated-gate bipolar transistor (IGBT) switches in power inverter and motor drive applications with features such as desaturation detection and secondary side power-on indication that are essential for IGBT drive applications.

The Si828x ISOdriver family provides industrial-grade isolation, optional integrated DC-DC converter, fast desaturation detection, superior timing characteristics, and exceptional noise and transient immunity.

The defining Si828x feature is a 4 amp gate driver coupled with desaturation detection to monitor the IGBT for overcurrent, in that event the Si828x driver initiates a controlled shutdown of the switch while updating the controller with the fault status, thus protecting the IGBT and the system. Additional integrated features include split outputs, a Miller clamp to prevent parasitic gate turn-on, and driver power state and fault feedback to the controller.
