S-1000N45-M5T1U

Supervisors Overview

The S-1000N45-M5T1U is a high-precision voltage detector manufactured by ABLIC Inc., designed for monitoring single-input power supply voltages. It operates within a supply voltage range of 950 mV to 5.5 V and features a threshold voltage of 4.5 V. The device utilizes an open-drain output configuration and maintains an accuracy of 1%. It functions reliably across a temperature range of -40°C to +85°C with a typical operating current of 350 nA. Packaged in an ultra-small SOT-23-5 format, it supports surface-mount installation without requiring manual reset or watchdog timer functionality.

Supervisors Feature Summary

• Ultra-small package design suitable for space-constrained applications
• High-precision voltage detection with 1% accuracy
• Low power consumption for battery-operated systems

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Battery-powered equipment needing reliable voltage supervision
• Embedded systems utilizing low-voltage logic circuits

Supervisors Procurement Notes

Verify the specific threshold voltage and output type against the official datasheet before integration. Confirm that the SOT-23-5 package dimensions align with your PCB footprint requirements. Ensure the operating voltage range covers your system's minimum and maximum supply conditions. Check for any recent manufacturing changes or compliance updates from ABLIC Inc. regarding RoHS or REACH standards.

Supervisors Selection Notes

Select this component when a fixed 4.5 V threshold is required for single-channel supervision. The open-drain output necessitates an external pull-up resistor for proper logic level interfacing. Consider the 350 nA quiescent current if power efficiency is critical. The absence of a reset delay or watchdog timer simplifies circuit design but requires external timing components if those features are needed.

Supervisors Part Context

This part belongs to the S-1000 series of voltage detectors from ABLIC Inc., known for high precision and compact packaging. The series offers various threshold voltages and output types to suit different supervisory needs. The S-1000N45-M5T1U specifically provides a 4.5 V threshold with an open-drain output, fitting into the broader portfolio of low-power PMIC solutions.

Supervisors Replacement Considerations

S-1000C45-M5T1U: Offers CMOS output instead of open-drain with identical threshold and package.
