S-1003NA31I-I6T1U

Supervisors Overview

The S-1003NA31I-I6T1U is a supervisory circuit manufactured by ABLIC, designed for monitoring single-channel voltage levels. It operates within a supply voltage range of 950 mV to 10 V and features a fixed threshold voltage of 3.1 V. The device provides an active low, open-drain output signal. It includes a manual reset function and incorporates a reset delay time of 10 ms to ensure stable system recovery. The component supports surface-mount installation in an SNT-6A-6 package and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a manual reset input for controlled system initialization
• Provides active low open-drain output for flexible logic interfacing
• Includes internal reset delay timer to prevent false triggering during power transitions

Supervisors Applications

• Microcontroller unit (MCU) power supply supervision
• Battery-operated device voltage monitoring
• Embedded system reset management

Supervisors Procurement Notes

Verify the specific suffix I6T1U corresponds to the required tape-and-reel packaging configuration and lead frame material. Confirm that the 3.1 V threshold aligns with the target application's minimum operating voltage requirements. Ensure compatibility with the SNT-6A-6 footprint dimensions and thermal characteristics during PCB layout review.

Supervisors Selection Notes

Select this component when a fixed 3.1 V detection level is required for single-rail monitoring. The manual reset capability distinguishes it from automatic-only detectors, allowing external control over the reset state. Consider the open-drain output structure if level shifting or wired-OR connections are necessary within the design architecture.

Supervisors Part Context

This part belongs to the S-1003 series of voltage detectors from ABLIC. The series focuses on compact, low-power supervision solutions suitable for portable electronics. The NA variant typically denotes standard commercial grade specifications, while the I6T1U suffix indicates the specific reel packaging and pin configuration for automated assembly processes.

Supervisors Replacement Considerations

Cross-reference with other S-1003 variants featuring identical 3.1 V thresholds and manual reset functionality. Verify pinout compatibility with the SNT-6A-6 package before substituting with alternative manufacturers' equivalents.
