Overview

Description
The LB1939T is a two-phase excitation bipolar stepping motor driver designed for low voltage operation, low saturation voltage, and low power consumption. It supports both constant voltage and constant current drive, enabling control of two iris motors. The IC is suitable for shutter, iris, and AF drive in 3V 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 Vpp 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)

Applications
Shutter drive
Iris drive
AF drive
3V battery-operated still digital cameras
Other battery-operated equipment
