APPLICATION NOTES

Auto Restart Protection/Current Limit Protection

When the fan motor is locked, the device will cut off the drive current within two to six seconds and restart automatically

after a few seconds. 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).

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).

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).
