(
7) I/O of hysteresis amplifiers
Note that resistance values of the I/O circuits can vary
±
30%
(2)
Torque control
The R
NF
-pin output voltage is plotted against the torque
control input voltage (E
C
) in Fig. 10.
(3)
The I/O equivalent circuit of the start/stop pin is shown
in (1). 1) of “Precautions for use.” The pin has a tempera-
ture dependence of
7mV/ C, and the resistance can
vary
±
30%. Take the temperature effect into consider-
ation when designing your application.
Start/stop pin

The I/O equivalent circuit of the Hall input pins is shown
in (1). 5) of “Precautions for use.” The Hall devices can
be connected in either series or parallel.
Hall input

The output current can be limited by applying a voltage
to the torque limit pin. Control is provided so that this pin
will have the same potential as the power ground pin.
Note that there is a voltage offset on this pin. The R
NF
-pin
voltage is 0.325V when the TL-pin voltage is 0.4V (typi-
cal) and the R
NF
-pin resistance is 0.5
. Note that the volt-
age offset changes with the R
NF
-pin resistance.
Torque limit pin (pin 18)

Unpredictable outputs may occur when the amplifier in-
put is outside the recommended range.
Amplifiers 1 and 2
(7)
An input range of 0.6V to (V
CC
Unpredictable outputs may occur when the input is out-
side this range.
Hysteresis amplifier
1.2V) is recommended.
(8)
The circuit puts the driver outputs (A1, A2, and A3) to the
open state at the temperature of 175 C (typical). There
is a temperature difference of about 20 C between the
temperatures at which the circuit is activated and deacti-
vated.
