4. Output protection function (C pin)
This pin connects the capacitor that forms the automatic recovery circuit. If rotation stops due to, for example, a
motor overload, the pin voltage rises and the output stops. The system automatically recovers from stopped to drive
mode when the load is set to an appropriate level. The lock detection time can be set by changing the value of the
capacitor.
For a 1-μF capacitor:Lock detection time
Lock protection time (output on)
(output off) About 6 seconds
About 2 seconds
About 1 second

While the blades are turning, the capacitor is charged with a current of about 3 μA (typical), and C is discharged by
pulses that correspond to the motor speed.
When the blades lock, the capacitor is no longer discharged, and the voltage across the capacitor increases. The
output is turned off when that voltage reaches 0.8
×
V
IN
.
When the output is turned off, the capacitor is discharged at a current of about 0.44 μA (typical). When the
capacitor voltage falls under V
TH
2, if the lock state is not yet cleared the capacitor continues discharging until
V
TH
1. (Note that the output is turned on at this time.) These operations, i.e. items
and
, are repeated with a
ton:toff ratio of about 1:6 to protect the motor.
{
If the lock state has been cleared when the capacitor voltage reaches V
TH
2, motor rotation is started by turning the
output on.
5. Rotation detection signal (RD pin)
This is an open collector output, and outputs a low level in drive mode and a high level when the motor is stopped.
6. Radio-frequency noise reduction function (B1 and B2 pins)
These are base pins for Darlington pair outputs. Add capacitors of about 0.01 to 0.1 μF if radio-frequency noise is a
problem.
7. Thermal shutdown function
Turns off the output in response to coil shorting or IC overheating.
