Bare Die Product Detail: SiS4080A

Full-Bridge Driver:
80V/2.6A Peak Full Bridge FET Driver with Charge Pump & Comparator. Switch frequency >1MHz enables drive of Voice Coil Motors, Switching Power Amplifiers & Power Supplies. Brushed + Stepper Motors can be driven via Single/Dual configs respectively.
Produced using a unique SOI (Silicon-On-Insulator) design, this device is a ruggedized electrical upgrade of the industry standard HIP4080A. The SiS4080A is specified for high reliability & enhanced performance over temperature.
  • Latchup free operation via all-around dielectric isolation
  • Reduced leakage current & parasitic capacitance for improved power consumption & higher speed
  • Enhanced stability at high temperature
  • N-Channel FET full bridge with high side chop capability
  • Built-in hysteresis comparator assists Voice Coil Motor Drive & Audio Amplifier applications
  • Maximum bootstrap supply voltage 95VDC
  • 1000pF load drive at >1MHz, tr / tf = 10ns
  • User-programmable dead time
  • Charge-pump & bootstrap maintain upper bias supplies
  • DIS (Disable) pin pulls gates low
  • Input logic thresholds interface 5V to 15V logic levels
  • Very low power consumption
  • Under-voltage protection
  • Wide automotive temperature range
