*3: This is a design guarantee and is not tested in individual units. The thermal protection circuit is included to prevent any thermal damage to the IC. Since this
would imply operation outside the IC's guaranteed temperature range, the application thermal design must be such that the thermal protection circuit will
not operate if the fan is operating constantly.
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 and ground lines
The IC ground is the control current power supply system ground, and the external n-channel transistor ground is the motor power
supply system ground.
These two systems should be formed from separate lines and the control system external components should be connected to the
IC ground.
*2. Regeneration power supply stabilization capacitor
Use a 4.7µF/25V capacitor at least for CM, which is the power supply stabilization capacitor for both PWM drive and kickback
absorption.
The capacitor CM must be connected to prevent destruction of the IC when power is applied or removed.
*3.Speed Control
(1) Control voltage
The PWM duty is determined by comparing the VTH pin voltage with the PWM oscillator waveform.
When the VTH voltage falls, the on duty increases and when the VTH voltage falls below the PWM output low level, the duty will
go to 100%.
(2) Thermistor
For thermistor applications, normally the 6VREG level will be resistor divided and the divided level input to the VTH pin.
The PWM duty is changed by changes in the VTH pin voltage due to changes in temperature.
*4. Current limiter setting
The current limiter circuit operates if the voltage across the resistor between V
and the VM pin exceeds 0.5V.
Since the current limiter circuit applies limitation at a current determined by I = VRf/Rf (where VRf = 0.5V (typical), Rf:
CC
O
resistance of the current detection resistor), the current limiter will operate at I = 1A when Rf = 0.5.
O
The resistor RF must be connected in the circuit and it must have a value such that the circuit operates within the recommended
current limiter operating range.

*5.Hall sensor input
Lines that are as short as possible must be used to prevent noise from entering the system. The Hall sensor input circuit consists of
a comparator with hysteresis (20mV). We recommend that the Hall sensor input level be at least three times this hysteresis, i.e. at
least 60mVp-p.
*6.PWM oscillator frequency setting capacitor
The PWM oscillator oscillates at f = 23kHz when CP is 200pF and at f = 46kHz when CP is 100pF, and this frequency becomes the
PWM reference frequency.
Note that the PWM frequency is given approximately by the following equation.
f [kHz] (4.6×106) ÷C [pF]
*7.FG output
This is an open collector output, and a rotation count detection function can be implemented using this FG output, which
corresponds to the phase switching. This pin must be left open if unused.
*8.HB pin
This pin provides a Hall effect sensor bias constant-voltage output of 1.25V.
*9.RMI pin
This pin is the speed control minimum speed setting.
The minimum output duty is set by R3 and R4. Leave R4 open to have the motor stop when the duty is 0%.
