Low-saturation, Low-voltage
2 Channels Bi-directional Motor Driver
General Specifications
The device is a two-channel low-saturation bi-directional motor driver IC. The design
is optimal for 2-dc motor or stepper-motor applications, such as driving shutter/iris on
cameras and other motor applications on portable devices.
