S-1000C18-M5T1G

Overview

The S-1000C18-M5T1G is a high-precision voltage detector manufactured by ABLIC Inc., designed for monitoring single-input power supply lines. It operates within a supply voltage range of 0.95 V to 5.5 V and features a threshold voltage of 1.8 V. The device utilizes CMOS technology to achieve an ultra-low operating current of 0.35 µA, ensuring minimal power consumption in battery-powered applications. It provides an active low CMOS output signal and is housed in a compact SOT-23-5 package. The component supports a wide operating temperature range from -40°C to +85°C.

Feature Summary

• Ultra-low power consumption achieved through specialized CMOS circuit design
• High detection accuracy with tight threshold voltage tolerance
• Compact surface-mount packaging suitable for space-constrained designs

Applications

• Battery-operated portable electronic devices requiring extended standby life
• Microprocessor system reset circuits for reliable startup sequencing
• Portable communication equipment monitoring critical voltage levels

Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to confirm package type and tape/reel specifications. Ensure compatibility with your PCB footprint and reflow soldering profile. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and lead times. Validate that the selected variant meets all environmental compliance requirements for your target market.

Selection Notes

Select this component when a fixed 1.8 V detection threshold is required for systems powered between 0.95 V and 5.5 V. The active low CMOS output is suitable for direct interfacing with most digital logic families. Consider the 0.35 µA quiescent current if battery longevity is a primary design constraint. Verify that the SOT-23-5 package dimensions fit within the mechanical constraints of the enclosure.

Part Context

This part belongs to the S-1000 series of voltage detectors from ABLIC, which are characterized by high precision and low power consumption. The series includes various threshold voltages and output types to accommodate different system requirements. The S-1000C18-M5T1G specifically offers a 1.8 V threshold with a CMOS output, distinguishing it from open-drain variants or those with different threshold settings within the same family.

FAQ

What is the output state of the S-1000C18-M5T1G when the input voltage is above the threshold?

When the monitored input voltage is higher than the 1.8 V threshold, the output pin is in the high-impedance state.

Does the S-1000C18-M5T1G include a manual reset function?

No, the S-1000C18-M5T1G does not feature a manual reset pin; the output state is determined solely by the monitored voltage level.
