ST1155A
Low-saturation, Low-voltage
Bi-directional Motor Driver
General Specifications
The device is a two-channel low-saturation bi-directional motor driver IC. The design is
optimal for stepper-motor applications, such as cameras, printers, FDDs, or other portable
devices.
Features and Benefits
z
Low voltage operation ( V
