Overview
The CS4161YN8 is a fully integrated bipolar stepper motor driver manufactured by onsemi. It features an internal dual H-bridge architecture capable of delivering up to 85 mA of output current per phase. The device includes built-in divide-by-select logic for step resolution control and incorporates Under Voltage Lockout (UVLO) for operational safety. Packaged in an 8-pin DIP configuration, it integrates both the control logic and power stages into a single component.
Feature Summary
- Fully integrated dual H-bridge design combining control and power stages
- Built-in divide-by-select functionality for flexible step resolution
- Integrated under voltage lockout (UVLO) protection mechanism
Applications
- Bipolar stepper motor driving in industrial automation
- Odometer mechanisms in automotive instrumentation
- Printer hammer drivers requiring low current actuation
Procurement Notes
Verify component status as this part may be obsolete. Confirm package type matches the 8-pin DIP specification. Ensure supply chain sources provide original manufacturer documentation. Check for alternative lead times due to potential discontinuation. Validate pin compatibility with existing PCB layouts before procurement.
Selection Notes
Select this component for applications requiring low-current bipolar stepper control without external power transistors. The integrated UVLO ensures reliability in varying supply conditions. Consider the fixed 85 mA limit when sizing for load requirements. The divide-by feature simplifies interface logic compared to discrete solutions.
Part Context
This device belongs to onsemi's legacy motor driver portfolio. It serves as a compact solution for simple stepper control tasks. The integration reduces bill of materials count by eliminating external switching components. It represents a specialized IC designed for specific low-power motion control niches.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Verify compatibility with any direct replacements through official datasheet cross-reference tools.
