Si8239x Isolated Gate Drivers

The Silicon Labs Si8239x isolators are ideal for driving power MOSFETs and IGBTs used in a wide variety of switched power and motor control applications. Based on our proprietary silicon isolation technology, our isolators provide high noise immunity, low prop delays and skew, reduced variation with temperature and age, and tight part-to-part matching. The Si8239x devices support up to 5 kVRMS withstand voltages. 

The Si8239x combines two isolated drivers with either an independent input control or a single input for high power applications. The Si8239x offers a wide variety of distinct features, including an output UVLO fault detection, feedback, automatic shutdown for both drivers, an EN (active high) instead of a DIS (active low) pin, a safe delayed start-up time of 1 ms, fail-safe drivers with default low in case of VDDI power-down, and highly precise dead time programmability. All drivers operate with a 2.5 V - 5.5 V input VDD and a maximum drive supply voltage of 24 V.   

Features

  • UVLO safety feature
    • UVLO status feedback to controller
    • Both drivers shutdown feature on UVLO fault
  • 1ms safe start-up delay: Allows safe system start-up
  • EN (active high) instead of DIS for added safety
    • EN pin ESD circuit does not power up chip
  • 2.5 V VDDI capability
  • High CMTI: 100kV/µs
  • Safety certified: UL, IEC/VDE, CSA, CQC
