Overview
The LS8297-S is a bipolar and unipolar stepper motor controller manufactured by LSI/CSI. It serves as a low-cost, low-current, pin-compatible replacement for the L297 component. The device integrates a power MOSFET driver to facilitate general-purpose motor control applications. It is designed to provide precision control for DC motors and stepper motors, featuring torque ripple reduction capabilities.
Feature Summary
- Integrates a power MOSFET driver for efficient motor actuation
- Functions as a pin-compatible replacement for the L297 controller
- Supports both bipolar and unipolar stepper motor configurations
Applications
- Precision control of DC motors
- Stepper motor control systems
- General-purpose motor control applications
Procurement Notes
Verify the manufacturer designation carefully, as the part number appears in listings associated with different entities including TE Connectivity/Raychem under similar codes. Confirm the specific datasheet version from LSI/CSI or authorized distributors to ensure compatibility with the intended L297 replacement application. Check current availability status as supply may be limited.
Selection Notes
Select this component when a direct pin-compatible upgrade or replacement for the L297 stepper motor controller is required. It is suitable for applications demanding low current consumption and cost-effective solutions. Ensure the system supports both bipolar and unipolar drive modes compatible with the integrated MOSFET driver architecture.
Part Context
LSI/CSI, originally LSI Computer Systems Inc., specializes in full custom and standard integrated circuit design. The LS8297 series represents their contribution to motor control ICs, offering alternatives to established industry standards like the L297. The product line includes variants such as the LS8297-CT and LS8297-TS.
Replacement Considerations
The LS8297-S is explicitly documented as a pin-compatible replacement for the L297 stepper motor controller. Verify that the target application does not require features exclusive to newer generations of controllers not present in this legacy design.
