Circuit operation
(1)
Hall input
The 3-phase Hall signal is amplified in the hall amplifiers
and sent to the matrix section, where the signal is further
amplified and combined. After the signal is converted to
a current in the amplitude control circuit, the current is
supplied to the output driver, which then provides a motor
drive current. The phases of the Hall input signal, output
voltage, and output current are shown in Fig. 5.
output
(2)
The R
NF
-pin current depends on the torque control input
voltage (EC) as shown in Fig. 6.
Torque control pin
(3)
The motor is in the run mode when the pin input voltage
is 3.5V or more, and in the idle mode (all output transis-
tors are off) when the voltage is 1.5V or less.
Start / stop pin
(4)
The R
NF
pin is the output stage ground pin. Connect a re-
sistor (0.5
recommended) between this pin and the
ground to monitor the output current.
Power ground pin (R
NF
pin)
(5)
Connect and adjust a capacitor between this pin and the
ground if the output tends to oscillate.
Phase compensation pin (C
NF
pin)
