STEPPER MOTOR CONTROLLER
- In stock 348
DESCRIPTION
· The LS8397 Stepper Motor Controller generates four phase drive signals for controlling two-phase Bipolar and four-phase Unipolar motors.
· It drives two H-bridges for Bipolar motors or four driver transistors for Unipolar motors.
· Supports full step mode in normal drive or wave drive, and half step mode.
· Features a dual PWM chopper circuit for current regulation in motor windings.
· Includes two inhibit outputs for controlling driver stages of each motor phase.
FEATURES
· Controls both Bipolar and Unipolar motors.
· Selectable torque ripple compensated phase drive.
· Automated switching between stepping and holding torques.
· Supply current < 400uA.
· Half and full step modes.
· Normal/wave drive.
· Direction control, Reset input, Step control input, Enable input.
· PWM chopper circuit for current control.
· Two over current sensor comparators with external references input.
· All inputs and outputs TTL/CMOS compatible.
· Operates from 4.75V to 7V.
APPLICATIONS
· Precision control of stepper motors in various industrial and consumer applications.
· Automation systems requiring accurate motor positioning.
· Robotics and CNC machines.
· Devices needing efficient motor control with low power consumption.
· Systems requiring smooth torque transition and reduced ripple.
