S-1009C12I-N4T1U

Supervisors Overview

The S-1009C12I-N4T1U is a voltage detector from the ABLIC S-1009 series, designed for ultra-low current consumption applications. It features a fixed threshold voltage of 1.2 V and operates within a supply voltage range up to 10 V. The device provides an active low, CMOS output type with a reset delay time of 26 ms. It supports one monitored input without manual reset or watchdog timer functions. The component is housed in an SC-82AB-4 package and is rated for operation between -40 °C and +85 °C.

Supervisors Feature Summary

• Ultra-low current consumption design suitable for battery-powered systems
• Fixed threshold voltage detection with high accuracy
• Active low CMOS output interface for direct logic connection
• Compact surface-mount packaging for space-constrained designs

Supervisors Applications

• Battery-operated portable electronic devices
• Microcontroller power supply monitoring
• Embedded system voltage supervision
• Low-power IoT sensor nodes

Supervisors Procurement Notes

Verify the specific package variant SC-82AB-4 against schematic footprints. Confirm the 1.2 V threshold aligns with target supply rails. Check RoHS compliance documentation for regulatory requirements. Ensure operating temperature range meets environmental specifications. Validate supplier authenticity through authorized distribution channels.

Supervisors Selection Notes

Select this component when a fixed 1.2 V detection level is required with minimal quiescent current. The CMOS output simplifies interfacing with digital logic compared to open-drain variants. Consider the SC-82AB-4 package size constraints during PCB layout. Compare against other S-1009 series parts if different thresholds or output types are needed.

Supervisors Part Context

Part of the ABLIC S-1009 series voltage detectors, which offer various threshold options and output configurations. The series targets applications requiring precise voltage monitoring with minimal power impact. Similar parts include S-1009N32I-N4T1U and S-1009C25I-I4T1U, differing in threshold voltage and output type.

Supervisors Replacement Considerations

Direct substitutes may include other S-1009 series parts with identical 1.2 V thresholds and CMOS outputs. Verify pin compatibility and package dimensions before substitution. Cross-reference with S-1009C12I-M5T1U if SOT-23-5 packaging is acceptable.
