Supervisors Procurement Notes

Verify the specific suffix 'B' against official ABLIC documentation to confirm the exact detection voltage and output characteristics, as suffixes define critical electrical parameters. Ensure the TO-92-3 through-hole package matches your PCB layout requirements. Confirm RoHS compliance status via the manufacturer's datasheet before integration into regulated products.

Supervisors Selection Notes

Select this component when a fixed 1.9 V threshold is required for system supervision. The TO-92-3 package is suitable for prototyping or applications where surface-mount space is not constrained. Consider the 1.3 μA current draw for battery life calculations. Verify that the N-ch open-drain output level compatibility aligns with the downstream logic input requirements.

Supervisors Part Context

This part belongs to the S-808xxC series of CMOS voltage detectors developed by ABLIC. The series emphasizes miniaturization and low power consumption for portable applications. The S-80819 variant specifically targets the 1.9 V detection point, offering a standardized solution for monitoring power rails near this voltage level without requiring external resistive dividers.

Supervisors Replacement Considerations

Cross-reference with other S-808xxC variants for different thresholds if voltage levels change. Check for equivalent parts from other manufacturers offering similar TO-92-3 voltage detectors with comparable 1.9 V thresholds and low quiescent current specifications.
