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.
Features
Low-voltage drive
— Dual power supply operation: VS = 1.6 to 7.5 V,
VDD = 1.9 to 6.5 V
— Single power supply operation: VS = VDD = 1.9 to
7.5 V
Low saturation voltage output: Vosat = 0.3 V at IO =
200 mA
Supports constant voltage and constant current drive
Built-in reference voltage circuit (Vref = 0.9 V)
Miniature, thin form package (Thickness t = 1.1 mm)
