S-1410J27-A8T1U4

Supervisors Overview

The S-1410J27-A8T1U4 is a supervisory circuit manufactured by ABLIC Inc., designed for monitoring system voltage levels. It operates within an input voltage range of 1.2 V to 5.5 V and features a fixed output threshold voltage of 2.7 V. The device utilizes an HSNT-8-A package, suitable for surface-mount applications. It integrates an internal oscillator-based watchdog timer with a timeout period of approximately 1.4 seconds, providing automated reset capabilities without requiring external components. The circuit supports active-high or active-low output configurations and includes a manual reset pin functionality.

Supervisors Feature Summary

• Integrates an internal oscillator watchdog timer for automated system recovery
• Provides precise voltage monitoring with a fixed 2.7 V threshold
• Supports configurable output polarity for flexible interface compatibility
• Includes manual reset input for direct system control

Supervisors Applications

• Microcontroller system supervision
• Watchdog timer implementation in embedded systems
• Voltage monitoring for portable electronic devices
• Automotive electronics power management

Supervisors Procurement Notes

Verify the specific output polarity configuration (active-high or active-low) required for your design, as this may be determined by ordering suffixes not explicitly detailed in general descriptions. Confirm the exact watchdog timeout duration matches application requirements, as internal oscillator variations can affect timing accuracy. Ensure the HSNT-8-A package dimensions align with PCB layout constraints. Cross-reference the manufacturer's latest datasheet for any updates on electrical characteristics or recommended operating conditions before finalizing procurement.

Supervisors Selection Notes

Select this component when a compact supervisory solution with integrated watchdog functionality is needed. The fixed 2.7 V threshold suits systems operating at or above this voltage level. Consider the HSNT-8-A package size for space-constrained designs. Evaluate whether the internal oscillator meets timing precision requirements compared to external RC-based solutions. Verify compatibility with the system's reset logic polarity and ensure the input voltage range covers the entire operational supply variation.

Supervisors Part Context

This part belongs to ABLIC's S-1410 series of supervisory circuits, which are designed for low-power applications. The series typically offers various threshold voltages and package options to accommodate different system requirements. The S-1410J27 variant specifically targets applications requiring a 2.7 V monitoring point with integrated watchdog features, distinguishing it from simpler voltage detectors or standalone watchdog timers.

Supervisors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. When evaluating potential replacements, ensure the alternative device matches the 2.7 V threshold, HSNT-8-A or compatible package, and integrated watchdog functionality. Verify that the replacement maintains similar input voltage ranges and output configuration options to ensure seamless integration without redesigning the surrounding circuitry.
