Brushless DC Fan Controllers and Fan Fault Detectors Products

Fan Controllers


Closed loop fan control includes look-up tables, PID loop control, alert to locked rotors and blocked air path. A majority of the PWM and linear fan controllers feature integrated temperature sensing.
Closed Loop Fan Controllers:


  • Built-in Fan ramp rate and Spin-up Control
  • Integrated temperature measurement
  • Multi-zone Control- up to 4 temps
  • 8 entry lookup tables


Fan Controller and Fault Detectors:


  • Temperature proportional fan speed control
  • FanSense technology protects against fan and system failure and eliminates need for 3-wire fans
