Toshiba BiCD process integrated circuit silicon monolithic TB67S249FTG TB67S249FTG 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. P-VQFN48-0707-0.50-004 Features Weight 0.14 g (typ.) • Built-in Anti-stall architecture (AGC: Active Gain Control) • Built-in sense resistor less current control architecture (ACDS: Advanced Current Detection System) • Low Rds (on) MOSFET (High side+ Low side=0.33 Ω (typ.
