• Embedded system voltage supervision
• Data storage integration in microcontroller systems

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and RoHS compliance status prior to acquisition. Note that availability may be limited due to product lifecycle status. Ensure packaging specifications match assembly requirements. Validate datasheet revisions against current design specifications.

Supervisors Selection Notes

Select this component when simultaneous voltage supervision and non-volatile data storage are required in a compact form factor. Consider the integrated EEPROM capacity and supervisor thresholds relative to system voltage rails. Evaluate the SOIC-8 package constraints against PCB layout limitations. Verify compatibility with manual reset requirements and output drive capabilities needed for the target logic family.

Supervisors Part Context

This part belongs to the CAT1161 series of supervisory circuits from onsemi. The series combines power management functions with memory capabilities. Variants within the family differ primarily in threshold voltages and specific feature sets such as watchdog timers. The CAT1161WI-25-GT3 specifically denotes the 2.5 V threshold variant with tape-and-reel packaging.

Supervisors Replacement Considerations

Cross-reference with CAT1161WI-30-GT3 or CAT1161WI-45-GT3 for different voltage thresholds. Check CAT1162 series variants for alternative supervisor configurations. Verify pinout and electrical parameter compatibility before substitution.
