The thermal protection circuit is implemented to prevent the IC from being thermally damaged or burned when exposed to an environment exceeding
the guaranteed operating temperature range. Thermal design must be carried out so that the thermal protection circuit will never be activated while the
fan is running in a stable condition.
Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product performance may not be
indicated by the Electrical Characteristics if operated under different conditions.

GND
*1 <Power supply - GND wiring>
GRD of the IC is connected to the control circuit power supply system and GRD of the external N-channel is
connected to the motor power supply system. Groundings must be installed separately and all external control
components must be connected to the GND line of the IC.
*2 <Power stabilization capacitor for regeneration>
For the CM capacitor, that is a power stabilization capacitor for PWM drive and for absorption of kick-back, a
capacitance of 4.7F/25V or higher must be used. The CM capacitor must be connected without fail to prevent the
IC from being damaged when power is tuned on or off.
*3 <Speed control>
1) Control voltage
The PWM duty ratio is determined by comparing the VTH pin voltage and the PWM oscillation waveforms.
When the VTH pin voltage drops, the 'ON' duty ratio increases, and when it drops to or below the PWM output L
level voltage, the duty ratio is 100%.
2) Thermistor
In thermistor applications, the 6VREG voltage is usually divided by a resistor, and the voltage thus generated is
supplied to the VTH pin.
The PWM duty ratio is varied by the changes in the VTH pin voltage which result from changes in temperature.
*4 < Setting the current limiter >
The current limiter is actuated when the voltage of the current-sensing resistors between V
0.5V or more.
and VM increases to
CC
Since the current of a current limiter circuit is limited by the current determined by I = VRf/Rf (where VRf = 0.5V
O
typ, Rf: current-sensing resistance), the current limiter is actuated at I = 1A when Rf = 0.5. The Rf resistor must
O
be connected without fail, and its constant must be within the recommended operating range for current limiters.

*5 <Hall input>
Wiring need to be short to prevent carrying of the noise. The Hall input circuit is a comparator having a hysteresis of
20mV. It is recommended that the Hall input level be more than three times (60mVp-p) this hysteresis.
*6 < PWM oscillation frequency setting capacitor >
The oscillation frequency is 23kHz when CP = 200pF and 46kHz when CP = 100pF, and this serves as the PWM
fundamental frequency.
For the most part, the PWM frequency can be obtained from the following formula:
f [kHz] (4.6106) ÷C [pF]
*7 <RD output>
This is the open collector type output, which outputs ''L'' during rotation. It is set to 'OFF' when a lock is detected.
This output is left open when not in use.
*8 <HB pin>
This is a Hall element bias pin, that is, the 1.25V constant-voltage output pin.
*9 <RMI pin>
Lowest speed setting pin for speed control.
The minimum output duty setting is made with R3 and R4. The R4 is left open to stop operation at a duty ratio
of 0%.
