TB6674FG Datasheet PDF - Toshiba

●TB6674PG, 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.

●One-chip two-phase bipolar stepping motor driver (including two bridge drivers)

●Power saving operation is available.

●Standby operation is available. Current consumption ≤20 μA (typ.)

●Built-in punch-through current restriction circuit for system ability and noise suppression.

●TTL-compatible inputs INA, INB, PS, and Vs2B terminals
