Product Description

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
ON resistance PS = L : 2.9 Ω(Typ.)
PS = H: 7.9 Ω(Typ.)
High driving ability.
