S-1000C16-I4T1U

Overview

The S-1000C16-I4T1U is a high-precision voltage detector manufactured by ABLIC Inc., designed for monitoring single-input power supply lines. It operates within a maximum supply voltage of 5.5 V and features an active low, open-drain output configuration. The device provides a fixed threshold voltage of 1.6 V with a typical accuracy of ±1%. It includes a reset delay time of 26 ms to ensure stable signal generation during voltage transitions. The component supports manual reset functionality and is housed in an ultra-small SNT-4A package, suitable for space-constrained applications.

Feature Summary

• Ultra-small SNT-4A package design for compact board layouts
• High-precision voltage detection with ±1% accuracy
• Active low open-drain output for flexible interfacing
• Manual reset capability for system control

Applications

• Portable electronic devices requiring precise power monitoring
• Battery-operated systems with limited space constraints
• Embedded controllers needing reliable voltage supervision
• Consumer electronics with strict size limitations

Procurement Notes

Verify the specific suffix I4T1U against official ABLIC documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the SNT-4A package. Cross-reference the 1.6 V threshold requirement with system voltage rails to prevent false triggering. Confirm RoHS compliance status through current manufacturer declarations before finalizing procurement orders.

Selection Notes

Select this component when a single-channel voltage monitor with high accuracy is required in minimal footprint. The 1.6 V threshold suits low-voltage logic systems. Consider the open-drain output for level shifting needs. Verify that the 26 ms reset delay aligns with system startup timing requirements. Compare against other S-1000 series variants if different thresholds or packages are needed.

Part Context

This part belongs to the S-1000 series of voltage detectors from ABLIC, characterized by CMOS technology and ultra-small packaging. The series focuses on high precision and low current consumption for portable applications. The S-1000C16 variant specifically targets the 1.6 V detection range, distinguishing it from other threshold options within the same family.

Replacement Considerations

Direct substitutes include other S-1000 series parts with identical 1.6 V thresholds and SNT-4A packaging, such as S-1000N16-I4T1U, provided pinout and electrical characteristics match exactly. Verify package dimensions and thermal properties before substitution.
