Monolithic Digital IC

LB1939T

2 Channel H Bridge Constant Voltage/

Constant Current Driver IC

Overview

Package Dimensions

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.
