S-1009N27I-M5T1U

Supervisors Overview

The S-1009N27I-M5T1U is a voltage detector from the ABLIC S-1009 series, designed for monitoring single power supply rails. It operates within a maximum supply voltage of 10 V and features a threshold voltage of 2.7 V. The device provides an active low, open-drain output with a reset delay time of 26 ms. It functions reliably across a temperature range of -40°C to +85°C and is housed in a compact SOT-23-5 surface-mount package.

Supervisors Feature Summary

• Ultra-low current consumption design suitable for battery-powered applications
• Open-drain output configuration allows flexible interfacing with various logic families
• Compact SOT-23-5 package minimizes board space requirements

Supervisors Applications

• Portable electronic devices requiring extended battery life
• Microcontroller system supervision
• Battery-operated instrumentation

Supervisors Procurement Notes

Verify the specific suffix 'N' against the official ABLIC datasheet to confirm the exact threshold voltage and output characteristics, as suffix variations can alter electrical parameters. Ensure the ordering quantity aligns with manufacturer packaging standards, typically reels of 3000 units, to avoid handling fees or availability issues associated with cut tape orders.

Supervisors Selection Notes

Select this component when a 2.7 V detection threshold is required for systems operating up to 10 V. The open-drain output necessitates an external pull-up resistor; ensure the resistor value matches the target logic level and speed requirements. Confirm that the 26 ms reset delay meets the system's startup timing constraints before finalizing the design.

Supervisors Part Context

This part belongs to the S-1009 series of ultra-low IQ voltage detectors. The series offers multiple threshold options and output types to accommodate diverse supervisory needs. The S-1009N variant specifically denotes the open-drain output configuration, distinguishing it from CMOS push-pull variants within the same family.

Supervisors Replacement Considerations

S-1009C27I-M5T1U: Offers identical threshold but with CMOS push-pull output instead of open-drain.
