S-1000N25-N4T1U

Supervisors Overview

The S-1000N25-N4T1U is a high-precision voltage detector manufactured by ABLIC Inc., belonging to the S-1000 series. It operates within a supply voltage range of 950 mV to 5.5 V and features a fixed threshold voltage of 2.5 V. The device provides an open-drain output type with low active current consumption of 350 nA. It offers 1% accuracy and functions in temperatures from -40°C to +85°C. Packaged in the ultra-small SC-82AB-4 surface-mount format, it lacks manual reset, watchdog timers, or chip enable signals.

Supervisors Feature Summary

• Ultra-small SC-82AB-4 package design for space-constrained applications
• High-precision voltage detection with 1% threshold accuracy
• Low power consumption suitable for battery-operated systems

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Battery-powered equipment needing voltage supervision
• Embedded systems utilizing compact surface-mount layouts

Supervisors Procurement Notes

Verify the specific threshold voltage variant required, as the S-1000 series utilizes suffix codes to denote different trip points. Confirm that the SC-82AB-4 package dimensions align with your PCB footprint constraints. Ensure compatibility with the target operating temperature range of -40°C to +85°C for your specific environmental conditions before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed 2.5 V monitoring point is necessary within a 5.5 V maximum input limit. The open-drain output requires an external pull-up resistor configuration. Consider alternative series if manual reset functionality or higher voltage thresholds are required, as this specific model does not support those features.

Supervisors Part Context

This part belongs to the ABLIC S-1000 series of voltage detectors, designed for general-purpose power supply monitoring. The series emphasizes miniaturization through the SC-82AB package while maintaining high precision. It serves as a fundamental supervisory component for ensuring system stability during power fluctuations in consumer and industrial electronics.

Supervisors Replacement Considerations

S-1000N25-N4T1G is a lead-free equivalent variant within the same series offering identical electrical specifications.
