3. Hall Sensor Amplifier
Figure 2. Hall Sensor Interface
The hall current (I
H
) is determined as follows;
Where, R
H1
or R
H2
is an external limiting resistor and Ri is input impedance of hall sensor. An external resistor, R
H1
or R
H2
, can be
used to decide an amplitude of hall signal. The input range of hall amplifier is between 0.3V and V
CC
-1.0V as shown in following fig-
ure.

4. Open Collector FG and 1/2FG Output for Speed Feedback
The FG output comes from the hall amplifier output. Because the FG output is open collector type, end user can pull up this pin with
a external resistor to the supply voltage of their choice(that is 5 or 3.3V). This FG output signal has two pulses per revolution on a four
pole motor and 1/2FG output signal has one pulse per revolution on a eight pole motor. It is recommended that this FG output be
higher than the GND potential.
5. Supply Voltage Consideration
A supply sustain capacitor(C
R)
should be placed as close to VCC pin with GND as layout permits. A reverse supply protection
diode(D
R
) prevent motor current from recirculating to power source when phase commutation occur. This results in increasing VCC
pin voltage. This capacitor absorbs motor recirculating current and limits VCC pin voltage. In general, large motor winding inductance
and current need large value of C
R.
6. Thermal Shutdown
TSD on: Two high side outputs are off.(Typ. 175
o
C)
TSD off:The circuit can be reactivated and begin to operate in a normal condition. (Typ. 150
o
C)
