LB1935T
LB1935CL
Overview
Monolithic Digital IC
Stepping Motor Driver IC
LB1935T/LB1935CL 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.
