Si828x ISOdriver Gate Drivers

Silicon Labs' Si828x isolated gate driver family provides ultimate protection for inverters and motor drives

Image of Silicon Labs' Si828x ISOdriver Gate Drivers Silicon Labs' 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.

Features
  • Industrial-grade isolation: high transient immunity, high reliability, 5 kVRMS withstand
  • Most comprehensive feature integration in the isolated gate driver market
  • Optional integrated DC-DC converter simplifying board layout and driver supply design
  • Industry's fastest desaturation detection: up to 10x faster than competitive alternatives
  • Fastest, most accurate timing specs with low propagation delay (<55 ns): up to 10x better than optocoupler solutions and up to 2x better than competing CMOS solutions
  • Long lifetimes under high-voltage conditions (100 years at 1000 V)

Applications

  • Motor control
  • Power inverters
