Application Circuit Example
*1.Power supply and ground lines
P-GND is connected to the motor power supply system and S-GND is connected to the control circuit power supply system.
These two systems should be formed from separate lines and the control system external components should be connected to
S-GND.
*2. Regeneration power supply stabilization capacitor
The capacitor CM provides power supply stabilization for both PWM drive and kickback absorption. A capacitor with a value of
over 0.1F is used for CM. A large capacitor must be used when the coil inductance is large or when the coil resistance is low.
Since this IC adopts a technique in which switching is performed by the high side transistor and regeneration is handled by the low
side transistor, the pattern connecting CM to VM and P-GND must be as wide and as short as possible.
*3.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.
*4.PWM oscillator frequency setting capacitor
If a value of 100pF is used for CP, the oscillator frequency will be f = 25kHz, and this will be the basic frequency of the PWM
signal.
*5.RD output
This is an open collector output. It outputs a low level when the motor is turning and a high level when it is stopped. This pin must
be left open if unused.
*6.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.
*7.HB pin
This pin provides a Hall effect sensor bias constant-voltage output of 1.25V.
*8.RMI pin
Connect this pin to VTH if unused. Even if unused, the IC is set internally to operate at a 10% drive duty at the voltage
corresponding to the lowest speed. (The capacitor is used to set up full-speed mode at startup.)
