... The FGR pin is an open-drained output. The output frequency is dividing the hall switching frequency with 2 for ST1117A, the same frequency with hall switching for ST1117B, and the rotating detection for ST1117C. With suitable pull up, the fan tachometer output can be used directly with bipolar or MOS logic for motor speed monitoring/control ...
