S-1000C18-N4T1U

Overview

The S-1000C18-N4T1U is a high-precision voltage detector manufactured by ABLIC Inc., designed for monitoring single-input power supply rails. It operates within a supply voltage range of 950 mV to 5.5 V and features an open-drain output type. The device provides a threshold voltage of 1.8 V with an accuracy of 1%. It consumes a typical operating current of 350 nA and dissipates up to 350 mW. The component functions reliably across a temperature range of -40°C to +85°C and is housed in an SC-82AB-4 surface-mount package.

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

Applications

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

Procurement Notes

Verify the specific suffix N4T1U against official ABLIC documentation to confirm pinout and electrical characteristics. Ensure compatibility with the target PCB footprint, specifically the SC-82AB-4 package dimensions. Cross-reference the 1.8 V threshold requirement with system specifications to prevent false triggering during normal operation fluctuations.

Selection Notes

Select this component when a precise 1.8 V detection point is required with minimal quiescent current. The open-drain output allows for flexible interfacing with various logic levels. Consider the 5.5 V maximum input limit and ensure the monitored rail does not exceed this value under any transient conditions.
