TA8068L

TA8068L TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC TA8068L INTELLIGENT STEPPING MOTOR DRIVER The TA8068L 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. FEATURES l Output current capacity l Low standby current : 1.5A (ｍax.) : 100μA (max.) Weight: 7.95 g (typ.) l Built−in Protective Functions : Over-Voltage Protection / Short-Circuit Protection (latch) / Thermal-Shutdown l Self−diagnostic Output : On Short-Circuit Detection l Separate GND for output and logic control sections l Plastic package HSIP-12pin BLOCK DIAGRAM AND PIN LAYOUT 1 2002-02-27 PIN DESCRIPTION TA8068L PIN No. 1 2 3 4 5 6 7 8 9 10 11 12 SYMBOL VCC ST INA OA OA P-GND NC OB OB INB L-GND DG 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 which controls output condition of pin 4 and pin 5.PNP-type voltage comparator is built in. PNP-type complementary outpu...
