TA7774FAG Datasheet Stepping Motor Driver

Manufacturer: Toshiba

Overview: TA7774P/PG/F/FG 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.
