TB6674PG

TB6674PG/FG/FAG TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB6674PG, TB6674FG, TB6674FAG Stepping Motor Driver IC 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. TB6674PG Features z They are similar substituting products of TA7774PG, TA7774FG, and TA7774FAG. Both products have same packages and same pin assignments. z One-chip two-phase bipolar stepping motor driver (including two bridge drivers) z Power saving operation is available. z Standby operation is available. Current consumption ≤ 20 μA (typ.) z Built-in punch-through current restriction circuit for system reliability and noise suppression. z TTL-compatible inputs INA, INB, PS, and Vs2B terminals z ON resistance PS = L : 2.9 Ω (Typ.)
