Supervisors Procurement Notes

Verify the specific suffix GT3 corresponds to the standard tape-and-reel packaging format when sourcing. Confirm that the 2.7 V threshold aligns with your target circuit's trip point requirements. Ensure the TSOT-23-5 footprint matches your PCB layout constraints. Check current availability status as this component may have limited stock due to its lifecycle stage.

Supervisors Selection Notes

Select this component when a fixed 2.7 V supervision threshold is required for systems operating between 1.6 V and 5.5 V. The manual reset feature allows for external intervention during fault conditions. Consider the open-drain output compatibility with your logic levels. Evaluate the thermal performance within the -40°C to +85°C range for your specific application environment.

Supervisors Part Context

This part belongs to onsemi’s CAT808 series of low-power voltage supervisors. It complements other variants in the family that offer different threshold voltages and output configurations. The series is designed for applications requiring reliable power management in space-constrained designs. It serves as a critical component for maintaining system integrity during voltage fluctuations.

Supervisors Replacement Considerations

Direct substitutes include other CAT808 variants with adjusted threshold voltages if 2.7 V is not strictly required. Cross-reference with similar voltage detectors from other manufacturers ensuring compatible pinouts and electrical characteristics. Verify that any replacement maintains the manual reset capability and open-drain output structure.
