1 / 7 page Ordering number : ENN6194 22704TN (OT) No. 6194-1/7 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) Package Dimensions unit: mm 3246-TSSOP20 LB1939T SANYO Electric Co.,Ltd.
