Overview
The LB1939T is a two-phase excitation bipolar stepping
motor driver that features low voltage operation, a low
saturation voltage, and low power consumption. It
supports constant voltage and constant current drive, can
control two iris motors, and is optimal for shutter, iris, and
AF drive in 3 V battery operated still digital cameras and
other battery operated equipment.
