2-Phase Stepping Motor Driver 19-Pin ZIP

The STK672-732A-E is a hybrid IC for use a unipolar, 2-phase stepping motor driver Hybrid IC. It features the use of A, AB, B and BB 2-pahse input signals. It is with built-in current resistor. and motor current is set by the voltage on the Vref pin. In addition the STK672-732A-E has various protective functions against over-current and over-heat. And it is pin-compatible with STK672-740A-E.

• Protective function against over-current and over-heat is built in
• Common-mode input protection circuit is built in
• Current detection resistors is built in
