(see figure 1 below). application notes figure 1 current limit protection pulse sensor/tachometer signal/fg pulse sensor is for detecting the rotational speed of the fan motor. at locked rotor condition, the signal stops cycling and the output is fxed at voh or vol (see figures 2~3 below). vs=4~5 v figure 3 fg signal output circuit: open collector ic=10m a max figure 2 output waveform pmw control signal a speed control lead can be provided that will accept a pwm signal from the customer circuit to vary the speed of the fan. the change in speed is linear by changing the duty-cycle of the pwm. open collector type and pull-up voltage is changed by maximum operating voltage and sink current by consuming current. (see figure 4 below).
