Toshiba Electronics Europe TB67S549FTG

The new TB67S549FTG, is an ultra-small and highly integrated stepping-motor driver that helps miniaturize product designs and enhance reliability while cutting the bill of materials and time to market.

The TB67S549FTG also integrates a complete set of protection functions, including overcurrent detection, thermal shutdown, and under voltage lockout.

Alongside the stepping motor IC, a compact evaluation board is available. Created in partnership with MIKROE, the Stepper 12 Click board™ is supported by a mikroSDK compliant library and simplifies software development.
