LB1937T
Overview
1-2 Phase Excitation Stepping Motor Driver
The LB1937T is a 2-phase bipolar drive stepping motor driver IC that supports low-
voltage drive and can drive two stepping motors at the same time.
The LB1937T's miniature package and minimal number of external components reduces the required mounting area.
It also provides high-efficiency motor drive and can reduce circuit current consumption.
Since it provides a current detection pin and supports PWM control input, it can be used to implement current chopper control at the system level.
The LB1937T is optimal for the stepping motors used for lens drive in digi...
