LB1906CL
Overview
Monolithic Digital IC
Stepping Motor Driver IC
LB1906CL is IC with forward/reverse motor drive 2-channel in which low saturation voltage and low voltage operation
possible. Its small sized package is optimal for 2 phase excitation drive of 2 phase bipolar stepping motors for various
portable devices such as digital still cameras.

2-phase excitation.
The logic output is determined according to which H state is input first. (See note 2.)
Note 1. The "-" symbol in the table indicates a "don't care" value.
Note 2. If H/H values (both high) are input to IN1 and IN2 with the timing shown in (1) below, the IN2 high state, which
is input later than the IN1 high state, will be ignored, and that input state will be handled as an IN1/IN2 = H/L
input state. Similarly, the case shown in (2) below is handled as an IN1/IN2 = L/H input state.
