Overview
The L6506D is a linear integrated circuit designed to sense and control current in stepping motors. It operates with a supply voltage range of 4.5V to 7V and features a maximum collector-emitter voltage (Vceo) of 7V. The device supports an output current of 2.75mA and draws a supply current of 25mA. It is housed in a 20-pin SOIC surface-mount package, measuring 13mm in length and 2.35mm in height. The component functions within a temperature range of -40°C to 150°C.
Feature Summary
- Senses and controls current in stepping motors and similar devices
- Performs interface functions from control logic through the power stage
- Forms constant current drive for inductive loads when paired with compatible drivers
- Allows synchronization of multiple devices via a dedicated sync pin
Applications
- Stepping motor current control systems
- Inductive load constant current drives
- Motor controller interfaces using L293 or L298 drivers
- Multi-device synchronized motor control setups
Procurement Notes
Verify the specific suffix against official STMicroelectronics documentation to confirm exact packaging and tape/reel specifications. Ensure compatibility with intended driver ICs such as L293 or L298 for proper system integration. Confirm operating temperature requirements align with the specified -40°C to 150°C range before finalizing procurement decisions.
Selection Notes
Select this component for applications requiring precise linear current sensing in stepper motors. It is suitable for designs utilizing parallel interface logic and external half-bridge drivers. Consider the 20-pin SOIC footprint for PCB layout constraints. Verify that the 7V maximum voltage rating meets the system's electrical requirements.
Part Context
The L6506D belongs to the L6506 series of current controllers for stepping motors. It is part of a chipset family that includes drivers like the L293 and L298 to form complete constant current drive solutions. This series is designed for general-purpose motor control applications requiring reliable current regulation.
