TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA7774P/PG, TA7774F/FG, TA7774FAG
Stepping Motor Driver IC
The TA7774P/PG and TA7774F/FG/FAG are two-phase bipolar
stepping motor driver ICs designed especially for 3.5- or 5.25-inch
FDD head actuator drives.
The ICs have a dual-bridge driver supporting the bipolar driving of
induced loads, a power-saving circuit, and a standby circuit. They
are ideal for achieving reduced set size and lower power
consumption.
Features
One-chip two-phase bipolar stepping motor driver
Power saving operation is available.
Standby operation is available.
Current consumption ≤ 115 A
Built-in punch-through current restriction circuit for system
reliability and noise suppression
TTL-compatible inputs INA, INB, and PS pins
High driving ability
