Pololu TB67S249FTG Stepper Motor Driver Compact Carrier

This is a TB67S249FTG Stepper Motor Driver Compact Carrier. This product is a carrier board or breakout board for Toshiba’s TB67S2x9FTG family of stepper motor drivers; we therefore recommend careful reading of the corresponding driver’s datasheet before using this product. This stepper motor driver lets you control one bipolar stepper motor and is available in two different versions: the TB67S249FTG  can deliver about 1.6 A per phase continuously (4.5 A peak), and the TB67S249FTG can deliver about 1.1 A per phase continuously (2 A peak). This breakout board for Toshiba’s TB67S249FTG micro stepping bipolar stepper motor driver is arranged in the popular 16-pin Pololu form factor, making it a more compact alternative to our full breakout. This TB67S249FTG Stepper Motor Driver Compact Carrier features adjustable current limiting and seven micro-step resolutions (down to 1/32-step). Additionally, it dynamically selects an optimal decay mode by monitoring the actual motor current, and it can automatically reduce the driving current below the full amount when the motor is lightly loaded to minimize power and heat. The TB67S249FTG has a wide operating voltage range of 10 V to 47 V, and our carrier board can deliver approximately 1.6 A per phase continuously without a heat sink or forced air flow (up to 4.5 A peak). It features built-in protection against under-voltage, over-current, and over-temperature conditions.

Features:

1. Simple step and direction control interface
2. Seven different step modes: full-step, non-circular half-step, circular half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
3. Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates
4. Advanced Dynamic Mixed Decay (ADMD) dynamically switches between slow and fast decay modes by monitoring the state of current decay (not according to fixed timing)
5. Configurable Active Gain Control (AGC) can be enabled to automatically reduce drive current by up to 40% to minimize power consumption and heat generation when maximum torque is not needed.
6. Motor supply voltage: 10 V to 47 V
