If the lock situation is continued, the device will work on a repeated cycle of cut-off and restart until the lock is released. (See Figure 1 below). Figure 1 Current Limit Protection Lock Sensor/Rotation Detector Lock Sensor is used to detect if the fan motor is operating or stopped. Alarm High: the output will be logical low when fan is operating and be logical high when fan motor is locked. (See Figures 2~3 below). Figure 3 RD Signal Output Circuit: Open Collector Figure 2 Alarm High Output Waveform Ic=5mA max 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 fixed at VoH or VoL (See Figures 4~5 below). Figure 4 Output Waveform Figure 5 FG Signal Output Circuit: Open Collector Ic=10mA max 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 6 below).
