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.

PIN DESCRIPTION
PIN No. 1 SYMBOL VCC

DESCRIPTION Power supply pin. This pin has a function to turn off the output when the applied
voltage exceeds 30V (Typ.), thus protecting the IC and the motor load. When this pin is opened or grounded, the output turns off, thus reducing the current consumption to 100µA or less. If standby mode is not needed, the pin is connected to VCC. This is input terminal wh...
