Sample Application Circuit
Description of Operation
The DC 3-phase brushless motor generally uses a permanent magnet for the rotor and places the stator coil around it.
When the rotor and stator coil are excited, magnetic force is generated between the poles, which is used for revolution
torque. For efficient revolution it is necessary to know precisely where the rotor pole is in relation to the stator pole. In
the brushless motor Hall devices and Hall ICs are widely used for this purpose, by detecting the electric power generated
along the lines of magnetic force.

Motor rotating force
The block diagram for this HIC is given in Fig. 2.
The conditions before input of V
1, with V
2 on, are START/STOP pin H level, CW/CCW pin H level, BRAKE
pin H level and Vref
pin (speed control input) H level. The position detect signal at this time, due to the effect of
the rotor magnetic field, will be output signals from 1 or 2 devices (of the 3) so that H
>H
is input to HIC pins 7
to 12. The signals input to pins 7 to 12 are input to the motor controller and converted into signals compatible with
3-phase brushless motor revolution. When V
1 is supplied the charge pump circuit activates, generating V
1
MOSFET gate voltage V
. This outputs excitation current to the motor phase windings as indicated in the timing
chart (Fig. 3), and rotating the motor.
For revolution speed control, the Vref
pin voltage is converted and used for PWM drive to increase GND transistor
efficiency, controlling the conduction of motor current Io (Fig. 1). Control of Io means control of power supplied
to the motor, which controls motor rpm. In general motor rpm N is proportional to the PWM on duty (when motor
load is constant). The PWM on duty is proportional to the size of Vref
1
(see Fig. 13), and the relation of N is as
outlined below.
