Supervisors Procurement Notes

Verify the specific suffix M5T2U corresponds to the required tape-and-reel quantity and packaging configuration. Confirm that the 4.635 V threshold aligns with the target system's undervoltage requirements. Ensure the SC-82AB-4 footprint matches the PCB layout. Check RoHS compliance status for the specific manufacturing batch before integration into final assemblies.

Supervisors Selection Notes

Select this component when a fixed 4.635 V threshold is required for automotive voltage monitoring. The low quiescent current makes it suitable for energy-sensitive applications. The wide input voltage range allows compatibility with various power rails. Verify that the open-drain output interface is compatible with the downstream logic levels and pull-up resistor configurations in the design.

Supervisors Part Context

This part belongs to the S-19101 series of voltage detectors from ABLIC. The series is characterized by CMOS technology implementation for low power and high accuracy. The S-19101 family includes variants with different thresholds and packages, tailored for both general-purpose and automotive supervisory roles.
