FUNCTION DESCRIPTIONS

HALL SENSOR LOCATION

The Fig 4 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 5). For the single-phase motor, this design

is very important.

H-BRIDGE TRANSISTOR OUTPUT

The Fig 6 is the circuit diagram of H-bridge transistors. The single-phase motor rotation

depends on a switching current of coil L1. When the magnetic pole is N pole, Q2, Q3, Q5 is

turn-off and Q1, Q4, Q6 is turn-on, L1 has a current from SO to NO. And when the magnetic

pole is S pole, Q1, Q4, Q6 is turn-off and Q2, Q3 is turn-on, L1 has a current from NO to

SO.

APPLICATION NOTE

The Example of Typical Application Circuit

Fig 7 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. R_Cis an external pull-up resistance for the use of measuring FG

signal. In view of the design, the value of R_Ccould be decided by the transistor saturation

voltage (V_ON), sink current (I_C), and off-level voltage (V_C).

C −

The formula is:

R_C=

For example:

V_C= +5V for TTL level.

I_C= 10mA at 0.2V saturation voltage

The safety value of R_C= 470

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.
