DC Fan Drive
The HV7100 controls the fans with a PWM supply voltage.
However, some fans require a steady DC voltage for proper
operation. In order for these fans to function properly, an LC
low pass filter should be added to cancel the PWM output to
a steady DC voltage.
The LC filter also provides another advantage. Some fans
draw large spikes of current during start-up and/or during
normal operation. Without the LC filter, these current spikes
would be drawn directly from the +24 or +48V supply, caus-
ing potential conducted EMI problems. The LC filter prevents
these spikes from occuring and/or reaching the +24 or +48V
supply.

Setting a Lower Speed Limit
When using the linear control input, the digital control in-
puts may be used to set a lower limit on the duty cycle. This
is based on the fact that the higher control setting, linear
or digital, dominates. In the example above, duty cycle is
prevented from falling below 25% even if the linear control
signal goes to 0V.
