Supervisors Procurement Notes

Verify the specific suffix 'GT3' to confirm tape and reel packaging requirements. Ensure compatibility with the TSOT-23-5 footprint during PCB layout. Confirm that the 2.19 V threshold aligns with the target supply rail. Check current availability status as distribution may vary by region. Validate RoHS compliance documentation for regulatory adherence.

Supervisors Selection Notes

Select this component when a fixed 2.19 V threshold is required for voltage supervision. The TSOT-23-5 package is suitable for space-constrained designs. Consider the active low reset polarity and push-pull output characteristics for interface compatibility. Verify operating temperature range suitability for the intended environment. Evaluate manual reset and watchdog needs against application logic requirements.

Supervisors Part Context

This part belongs to the CAT823 series of supervisory circuits from onsemi. The series offers various threshold voltages and output configurations to suit different power management needs. The CAT823YTDI-GT3 specifically targets applications requiring a 2.19 V trip point. It is part of a broader portfolio of voltage supervisors designed for reliability and efficiency in modern electronic systems.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives with similar threshold voltages. Verify if other CAT823 variants offer different thresholds or packages. Ensure substitute components maintain the same output type and reset functionality. Cross-reference datasheets for electrical parameter equivalence.
