Function Descriptions
HALL SENSOR LOCATION
The Fig 2 is the hall sensor location, where marks the IC number. The best sensitivity,
which can be intensified as much as possible, depends on the vertical distance and position
between magnetic pole and the hall sensor (Fig 3). For the single-phase motor, this design
is very important.

Application Note
The Example of Typical Application Circuit
Fig 4 is the example of typical application circuit. The red, yellow, and black wires are the
input points of the motor system: red, the input of power supply; yellow, the output of FG;
black, the ground signal. RC is an external pull-up resistance for the use of measuring FG
signal. In view of the design, the value of RC could be decided by the transistor saturation
voltage (VON), sink current (IC), and off-level voltage (VC).
V
C −
V
ON
The formula is:
RC=
I
C
For example:
VC = +5V for TTL level.
IC = 10mA at 0.2V saturation voltage
The safety value of RC= 470Ω
D1 is the reverse protection diode. As if the red and black wires reversely connect with the
power source, the current will flow through the ground via IC and coils L1 and L2 to power
supply. Under such kind of circumstances, the IC and coils are easy to be burned out.
Therefore, D1, the reverse protection diode, is necessary for the design. However, D1 will
also cause an extra voltage drop on the supply voltage.
C1 is a capacitor to reduce the ripple noise caused during the transient of the output stages.
The volume of the ripple noise depends on the coil impedance and characteristics.
