LB1800CL
Overview
Stepping Motor Driver IC
The LB1800CL is a 2-channel low-saturation drive low-voltage operation forward/reverse motor driver IC. Its ultraminiature package makes it optimal for 1-2 or 2 phase excitation drive of 2-phase bipolar stepping motors which are commonly used in various portable devices such as digital still cameras.

Logic output corresponding to the earliest high input is honored (Note 2).
Note 1: Hyphens in the "Output" columns denote the off (high impedance) state. Note 2: When inputs IN2/IN3=H/H are applied at the timing shown in (1) in the figure below, the latter input IN3 is ignored and the input logic IN2//IN3=H/L is performed. Similarly, IN2/IN3=L/H is performed in the input timing case of (2).
