Overview
The LS8293 is a micro-stepper motor controller manufactured by LSI/CSI. It functions as a bipolar and unipolar motor driver utilizing Power MOSFET technology with Pulse Width Modulation (PWM) interface capabilities. The component is housed in a 28-pin Dual In-line Package (DIP-28). It is designed for precise control of stepper motors, supporting both bipolar and unipolar configurations through its integrated driver architecture.
Feature Summary
- Integrated micro-stepping control functionality for enhanced motion precision
- Supports both bipolar and unipolar stepper motor configurations
- Built-in Power MOSFET drivers for direct motor interfacing
- Pulse Width Modulation (PWM) interface for signal processing
Applications
- Precision positioning systems requiring micro-stepping
- Industrial automation equipment using bipolar stepper motors
- Unipolar motor control applications in embedded systems
Procurement Notes
Verify the specific package variant, such as DIP-28, against project requirements. Confirm RoHS compliance status if environmental regulations apply. Ensure the supplier provides original manufacturer documentation to validate authenticity. Check for any specific ordering suffixes that may indicate temperature range or packaging differences. Cross-reference the part number with official LSI/CSI catalogs to confirm current production status.
Selection Notes
Select this component when micro-stepping resolution is required for smooth stepper motor operation. It is suitable for designs needing integrated bipolar and unipolar driver support within a single IC. Consider the 28-pin DIP package for through-hole mounting constraints. Evaluate PWM interface compatibility with the host controller. This device is appropriate for applications prioritizing integrated power stage simplicity over discrete solutions.
