Overview
The L297D013TR is a bipolar/unipolar stepper motor driver manufactured by STMicroelectronics, housed in a 20-SOIC package. It operates on a parallel interface with a supply voltage range of 4.75V to 7V and supports step resolutions of 1 and 1/2. The device integrates four half-bridge pre-drivers for output configuration and functions as a controller for commutation and direction management. It is designed for surface mount installation and maintains operational reliability across a junction temperature range of -40°C to 150°C.
Feature Summary
- Integrated controller providing commutation and direction management capabilities
- Supports both bipolar and unipolar stepper motor configurations
- Includes four half-bridge pre-driver outputs for direct motor connection
Applications
- Stepper motor control systems requiring integrated drive and logic
- Automation equipment utilizing bipolar or unipolar stepping mechanisms
- Industrial applications demanding robust thermal performance up to 150°C
Procurement Notes
Verify the specific suffix '013TR' corresponds to the tape and reel packaging format required for your assembly line. Confirm that the 20-SOIC footprint matches your PCB layout constraints. Ensure the 4.75V to 7V supply voltage aligns with your system design before procurement.
Selection Notes
Select this component when a combined logic controller and power driver is needed for stepper motors. It is suitable for designs requiring a single IC solution for commutation and driving. Consider the 20-pin package size and parallel interface requirements against available board space and signal routing options.
Part Context
This part belongs to the L297 family of stepper motor drivers from STMicroelectronics. It serves as a specialized power management and motion control integrated circuit. The device combines digital logic functions with power output stages to simplify the design of complex motor control circuits.
Replacement Considerations
Check for pin-compatible alternatives within the same manufacturer's portfolio if lead times are critical. Verify that any substitute maintains the same 20-SOIC package and electrical specifications for seamless integration.
