A.
Minimum speed setting (stop) mode. The low speed fan rotation occurs at the minimum speed set with the RMI pin.
When the minimum speed is not set (RMI pin pulled up to 5VREG), the motor stops.
B.
Low
high speed. PWM control is made by comparing the CPWM oscillation voltage (1.1 V 3 V) and VTH
voltage. Both upper and lower output TRs are turned ON when the VTH voltage is low. The upper output TR is turned
OFF when the VTH voltage is high, regenerating the coil current in the lower TR. Therefore, as the VTH voltage
decreases, the output on duty cycle increases, causing an increase in the coil current, raising the motor rotation
speed. The rotation speed can be monitored with the FG output.
C.
Full-speed mode. The full-speed mode becomes effective with the VTH voltage of 1.65 V or less. (VTH must be equal
to GND when the speed control is not used.)
D.
PWM-IN input disconnection mode. The full-speed mode becomes effective when the VTH voltage is 1.1 V or less.
Set VTH = GND when the speed control is not used.
