Description

UIM24301 stepper motor controller is a microprocessor embedded, voltage control, miniature stepper motor controller.

With the UIM24301, the motor speed can be controlled by an analog voltage in three optional ways:

1) the on-board trimmer, 2) an external potentiometer or, 3) an external voltage.

Run/stop, direction, high/low speed range and, enable/disable can be controlled simply by shorting the corresponding terminal to the ground. UIM24301 controllers can run the motor without user control device.

The microprocessor of the UIM24301 is capable to ramp up the current speed to the desired speed

within 0.5 seconds, even when the speed control voltage is changing. This feature makes the sudden increase of the desired speed become possible.

UIM24301 can provide 0 - 1A adjustable phase current. Their mixed-decay current control reduces

the back-EMF effect under high motor speed and improves the performance.

UIM24301 can be mounted onto user PCB through soldering or DIP18 socket.
