S-19100N46A-N4T2U

Supervisors Overview

The S-19100N46A-N4T2U is a supervisory circuit from ABLIC designed for automotive applications with operation up to 125°C. It features a fixed detection voltage of 4.6 V and an open-drain output type. The device supports manual reset functionality and includes a delay function for external delay time setting. It operates within a maximum supply voltage of 10 V and functions in temperatures ranging from -40°C to +125°C.

Supervisors Feature Summary

• Designed for reliable monitoring of supply voltages in automotive environments
• Ensures timely reset triggering through integrated delay function capabilities
• Utilizes CMOS technology for stable performance under high temperature conditions

Supervisors Applications

• Automotive voltage monitoring systems
• Supply voltage supervision in harsh thermal environments
• System reset control circuits requiring manual intervention

Supervisors Procurement Notes

Verify the specific suffix N4T2U against official ABLIC documentation to confirm package type and tape/reel specifications. Ensure compatibility with 125°C automotive operating requirements. Confirm that the open-drain output configuration aligns with your system's pull-up resistor design. Validate the 4.6 V threshold matches your target voltage level before procurement.

Supervisors Selection Notes

Select this component when a fixed 4.6 V threshold is required for automotive-grade supervision. The manual reset feature necessitates user interaction for recovery, distinguishing it from auto-reset variants. Consider the SC-82AB package size for space-constrained PCB layouts. Verify that the open-drain output interface is compatible with the downstream logic levels in your application design.

Supervisors Part Context

This part belongs to the S-19100 series of voltage detectors developed using CMOS technology. The series is specifically engineered for automotive use, offering high reliability at elevated temperatures. The S-19100N46A variant provides a precise fixed detection voltage, ensuring consistent monitoring performance across varying supply conditions without external calibration needs.

Supervisors Replacement Considerations

Check for other S-19100 series parts with different thresholds or reset types. Verify pinout compatibility if substituting with similar ABLIC supervisors. Ensure any replacement maintains the 125°C automotive rating and open-drain output structure.
