TB6674PG

Bipolar Motor Driver Power MOSFET Parallel 16-DIP

, TB6674FG, and TB6674FAG are stepping motor driver ICs with MOS output transistors.

  The ICs can control two-phase stepping motor forward and reverse by bipolar driving. They have a power-saving circuit and a standby circuit. 

Features

They are similar substituting products of TA7774PG, TA7774FG, and TA7774FAG. Both products have same packages and same pin assignments.
