When a fan is rotating, the capacitor is charge at 2.8 μA (typ) and discharged through the C with pulses according to the
rotational speed.
When a fan is locked, no discharge occurs through the C and the C voltage rises, turning OFF the output at V
TH
1 (0.7

).
When the output is turned OFF, discharge occurs through the C at 0.38 μA (typ). If the lock is not released when the C
voltage drops to V
TH

), the capacitor is charged to V

These operations

If the lock is released when the C voltage drops to V

Open collector output (Drive mode: ‘‘L’’, Stop mode: ‘‘H’’)
(6) Radio noise reducing (B1 and B2 pins)
These are the base pins for Darlington connected output transistors. If radio noise is a problem, add a capacitor of
approximately 0.01 to 0.1 μF between B1 and B2, or 0.001 μF to 0.01 μF between OUT and B.
