TA8068L

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 features of the TA8068L are: (1)output current capacity: 1.5A; (2)low standby current: 100A; (3)built-in protective functions: over-voltage protection/ short-circuit protection/thermal shutdown; (4)self-diagnostic output: on short-circuit detection; (5)separate GND for output and logic control sections; (6)plastic package HSIP-12pin.

The maximum ratings of TA8068L are: (1)supply voltage: 30V; (2)input voltage: -0.3 to 7V; (3)output voltage: -0.3 to VCC; (4)output current: 1.5A; (5)power dissipation: 25W; (6)operating temperature: -40 to 110; (7)storage temperature: -55 to 150; (8)lead temperature: 260.

The following is about the electrical characteristics of TA8068L: (1)current consumption: 12mA min, 25mA typical and 40mA max; (2)input voltage: 0.8V max; (3)input current: -50A min; (4)input voltage: 0.8V max; (5)output saturation voltage: 1.25V typical and 1.5V max; (6)output leakage current: 10A max; (7)output voltage: 0.3V max; (8)over-current detection: 1.8A min, 4A typical and 6A max; (9)over-voltage detection: 27.5V min, 30V typical and 33V max.
