Active Gain Control Clock-in control Bipolar stepping motor driver
The TB67S249FTG is a clock-in controlled bipolar stepping motor driver with a built-in Active Gain Control architecture. The TB67S249FTG also has an internal current feedback control (ACDS) which enables the driver to control the motor current without using a sense resistor. Using the BiCD process, the TB67S249FTG is rated at 50 V, 4.5 A.
