1
When a fan is rotating, the capacitor is charged at 3 μA (typ) and discharged through the C with pulses according to the
rotational speed.
2
When a fan is locked, no discharge occurs through the C and the C voltage rises, turning OFF the output at 0.8

V
IN
.
3
When the output is turned OFF, discharge occurs through the C at 0.44 μA (typ). If the lock is not released when the C voltage
drops to V
TH
2, the capacitor is charged to V
TH
1 again. (At this moment, the output is turned ON.)
These operations

If the lock is released when the C voltage drops to V
TH
2, the output is turned ON, starting rotation.
