Procurement Notes
Verify the specific suffix ID against official documentation to confirm industrial temperature rating compliance. Confirm availability status as the LX6431 family has been subject to discontinuation notices. Ensure the 8-SOIC package dimensions match the design footprint requirements before finalizing procurement decisions.
Selection Notes
Select this component when an adjustable high-voltage reference is required for battery-operated applications. The shunt topology allows for simple resistor-based voltage setting. Consider the ±2% tolerance and 100 mA output current capabilities against system load requirements. Verify that the operating temperature range meets the environmental conditions of the target application.
Part Context
The LX6431 series belongs to Microsemi's portfolio of precision voltage reference devices designed for portable electronics. These components utilize a bandgap reference architecture to provide stable voltage outputs. The series includes variants with different temperature ratings and package options to suit various embedded system constraints.
Replacement Considerations
Consult official Microsemi documentation for confirmed substitute part numbers. Cross-reference pinouts and electrical specifications carefully if considering alternative manufacturers.
