FM1233ACS3X

Supervisors Overview

The FM1233ACS3X is a fixed, single-channel power supply support circuit manufactured by onsemi. It operates within a supply voltage range of 4.5 V to 5.5 V and is housed in a compact SOT-23 (PDSO3) surface-mount package. Designed for reliability, the device supports an operating temperature range from -40°C to +105°C. The component functions as a supervisory circuit, providing essential monitoring capabilities for power systems.

Supervisors Feature Summary

• Provides fixed threshold supervision for single-channel power supplies
• Ensures system integrity through reliable voltage monitoring
• Compatible with standard surface-mount assembly processes

Supervisors Applications

• Power supply support circuits
• System supervisory applications
• Voltage monitoring in electronic equipment

Supervisors Procurement Notes

Verify that the specific suffix 'ACS3X' corresponds to the required tape-and-reel packaging configuration and environmental compliance status. Confirm that the fixed threshold characteristics align with the target design requirements, as this variant does not offer adjustable thresholds. Ensure the sourcing channel provides documentation confirming the manufacturer origin and RoHS/REACH compliance status.

Supervisors Selection Notes

Select this component when a fixed-voltage supervisory function is required for a single power rail within the specified input range. The SOT-23 package is suitable for space-constrained designs. Consider the -40°C to +105°C operating range for industrial or commercial environments. This part is appropriate where a simple, fixed-threshold reset or monitor signal is needed without complex configuration.

Supervisors Part Context

This component belongs to the FM1233 series of power supply support circuits. Variants within this family share similar core functionalities but differ in package types, suffixes indicating specific manufacturing or packaging options, and environmental certifications. The FM1233ACS3X represents a specific configuration optimized for surface-mount integration.

Supervisors Replacement Considerations

Direct substitutes include other FM1233 variants such as FM1233DDS3X or FM1233BAS3X, provided they match the required package and electrical specifications.
