STK672-732AN-E: Stepper Motor Driver, Unipolar 2-Phase

Product Description
The STK672-732A-E is a hybrid IC for use a unipolar, 2-phase stepper 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.
Features   Benefits
     
  • Protective function against over-current and over-heat is built in
 
  • Superior in safety drive
  • Common-mode input protection circuit is built in
 
  • When A and AB (or B and BB) turn on at the same time, it prevents destruction
  • Current detection resistors is built in
 
  • Easy to design and reduce the mounting area
