Typical Applications

Packaging

  • Transformer isolation barrier
  • Power-Thru integrated isolated bias
    • No need for high-side bootstrap
    • No need for external secondary-side bias  
  • AEC-Q100 Grade 2 qualification
  • 50 ns propagation delay
  • Separate drive output pins: pull-up (2.8 Ω) and pull-down (1.0 Ω)
  • Supply voltage 10.5 V < VDRV < 13.2 V
  • Undervoltage lockout on primary VDRV and secondary VSEC
  • Enable pin with fast response
  • Continuous ON capability—no need to recycle IN or recharge bootstrap capacitor
  • CMTI > 100 V/ns dv/dt immunity
  • Creepage distance 8.4 mm
  • Safety Regulatory Approvals
    • 5 kV RMS VISO per UL 1577
    • 8 kV pk VIOTM maximum transient isolation voltage
