TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TA8068F
Intelligent Stepping Motor Driver
The TA8068F is a stepping motor driver with a current capacity
of 1.5A. Inputs INA and INB are combined to control the four
outputs.
Since the inputs are TTL-compatible, this IC can be controlled
directly from a CPU or other control system.
The IC also incorporates various protective functions as well as a
self-diagnostic function for diagnostic function for diagnostic
output.
