Supervisors Procurement Notes

Verify the specific suffix K8T2U4 confirms the 2.958 V threshold and TMSOP-8 package configuration. Confirm RoHS compliance status and lead times directly with the manufacturer or authorized distributors, as availability may vary. Ensure the ordering information matches the required voltage monitor specifications for your design.

Supervisors Selection Notes

Select this component when a precise 2.958 V detection level is required for systems operating between 0.9 V and 6 V. The inclusion of a watchdog timer and manual reset capability makes it suitable for applications demanding robust fault recovery. Verify that the TMSOP-8 package fits the PCB layout constraints and thermal requirements.

Supervisors Part Context

This part belongs to the S-19400 series of voltage monitors from ABLIC. These devices are designed for low-voltage applications requiring reliable reset generation. The series typically offers various threshold voltages and packaging options to accommodate different system architectures and space limitations.

Supervisors Replacement Considerations

Check for other S-19400 variants with similar thresholds if exact pin compatibility is needed. Verify functional equivalence regarding watchdog timeout periods and reset delay times before substitution.
