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.
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
reliability 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.
