DESCRIPTION
The L6515 is a monolithic integrated circuit in
BCD-Technology assembled in a PLCC-44 plastic
chip carrier.
The device contains all functions for a complete
dual DC-Motor positioning system. For the motor
driver stage only digital switched bridges are
needed.
Useful are L293E, L298, L6203 and L6202. The
device is intended to drive DC-Motors in typewrit-
ers, printers, plotters and general purpose indus-
trial applications.

POSITION ENCODER
Main advantage of the operation principle of the
positioning system is that a high performance po-
sition encoder is not required.
The system accepts several phases and ampli-
tude errors of the encoder output signal without
affecting the system performance.
Two position sensors are useful.
1) Optical-Encoder with IR-LED and Phototransistor
Figure 1.
2) Magnetic Encoder with hall-effect sensors
Figure 2.
The allowed spread of the encoder output signal refer to reference level is shown in Fig.3.
