S-1003NB39I-M5T1U

Supervisors Overview

The S-1003NB39I-M5T1U is a manual reset delay voltage detector manufactured by ABLIC Inc. It operates within a supply voltage range of 0.7V to 6.0V and features a threshold voltage of 3.9V. The device provides an active low output signal with a typical reset delay time of 26ms. It is housed in a compact SOT-23-5 package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a manual reset function allowing external control over the reset state via a dedicated pin.
• Provides precise voltage monitoring with a fixed 3.9V detection threshold for system stability.
• Features a built-in delay timer to prevent false resets during power-up transients.

Supervisors Applications

• Microprocessor reset circuits requiring manual intervention
• Battery-powered devices needing reliable power supervision
• Embedded systems with strict startup sequence requirements

Supervisors Procurement Notes

Verify the specific suffix 'M5T1U' confirms the SOT-23-5 package and tape-and-reel packaging format. Ensure the 'I' grade designation matches your required operating temperature range of -40°C to +85°C. Cross-reference the datasheet for exact electrical characteristics at your target operating voltage to confirm compliance with system specifications.

Supervisors Selection Notes

Select this component when a manual reset capability is required alongside standard voltage monitoring. Compare the 26ms delay time against your system's startup timing constraints. Verify that the 3.9V threshold aligns with the minimum acceptable supply voltage for your load. Consider the SOT-23-5 footprint compatibility during PCB layout planning.

Supervisors Part Context

This part belongs to the S-1003 series of voltage detectors from ABLIC, which are designed for general-purpose power management applications. The series offers various threshold voltages and output configurations to suit different microcontroller and logic circuit requirements while maintaining low current consumption.

Supervisors Replacement Considerations

Direct substitutes include other S-1003 series variants with identical manual reset functionality but different threshold voltages, such as S-1003NB33I-M5T1U or S-1003NB45I-M5T1U, provided the voltage level meets system needs.
