TA8068F

TA8068F 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. FEATURES · · · · · · · Output current capacity : 1.5 A (max) Low standby current : 0.1 mA (max) Self−diagnostic Output : On Short-Circuit Detection Weight: 0.79 g (typ.) Built−in Protective Functions : Over-Voltage Protection/ Short-Circuit Protection(latch) / Thermal-Shutdown Recommended operating supply voltage range : VCC = 8~16 V Separate GND for output and logic control sections HSOP20-Pin Power Flat Pakage BLOCK DIAGRAM AND PIN LAYOUT LATCH R S R R CONTROL LOGIC MULT PROTECTION 1 VCC 4 ST 5 INA 6 OA 7 10 P-GND 14 OB 15 OB 16 INB 17 L-GND 20 DG OA 1 2002-02-27 TA8068F PIN DESCRIPTION PIN No. 1 SYMBOL VCC ST 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...
