ONTROL
DC motors can be controlled in an analog manner using
the OTA.
For the analog control an external transistor is required.
The OTA can supply the base current for this transistor
and act as a control amplifier (see Fig.8).

IRECTION FUNCTION
If the voltage at pin 10 is <0.8 V, the motor is running in
one direction (depending on the motor connections). If the
voltage at pin 10 >2.0 V, the motor is running in the other
direction.
BRAKE
FUNCTION
If the voltage at pin 9 is >2.0 V, the motor brakes. In that
condition, the 3 outputs MOT1, MOT2 and MOT3 are
forced at a LOW voltage level and the current limitation is
done internally by the sink drivers.
RESET
FUNCTION
If the voltage at pin 21 is >2.0 V, the output states are
shown in Table 2.
