CS8441YN8

Overview

The CS8441YN8 is a bipolar stepper motor driver manufactured by onsemi, designed for operation within a supply voltage range of 6.5V to 15.5V. It features an 85mA output current capability and utilizes an 8-pin DIP package with a 0.300-inch (7.62mm) width. The device supports half-bridge output configuration and includes divide-by-select functionality for step rate control.

Feature Summary

• Bipolar stepper motor drive capability
• Integrated divide-by-select function
• Half-bridge output configuration

Applications

• General purpose stepper motor control
• Low power automation systems
• Precision positioning devices

Procurement Notes

Verify component status as the CS8441YN8 is listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing PCB footprints for 8-DIP packages before procurement planning.

Selection Notes

Select this component for applications requiring simple bipolar stepper control without complex microstepping requirements. Consider the limited output current of 85mA when sizing for motor loads. Evaluate alternative active components if long-term supply stability is critical for the product lifecycle.

Part Context

This part belongs to the CS8441 series of stepper motor drivers from onsemi. It is a legacy component in the company's portfolio, primarily used in older designs or maintenance upgrades where specific pinouts and electrical characteristics are already established in the system architecture.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Engineers should consult onsemi technical support for modern equivalents or verify pin-compatible alternatives from other manufacturers that match the 85mA output and voltage specifications.
