S-19101N42A-N4T2U

Supervisors Overview

The S-19101N42A-N4T2U is an automotive voltage detector IC from ABLIC, designed for operation up to 125°C. It features a fixed detection threshold of 4.26V and supports a maximum supply voltage of 10V. The device utilizes an open-drain output configuration and includes an external delay time setting function. It is housed in a compact SC-82AB-4 package and meets AEC-Q100 automotive qualification standards.

Supervisors Feature Summary

• Automotive-grade design certified for high-temperature environments up to 125°C
• Incorporates an external delay time setting function for customized reset timing
• Utilizes CMOS technology for low current consumption and high accuracy

Supervisors Applications

• Automotive electronic control unit (ECU) power monitoring
• Battery voltage supervision in electric vehicles
• Engine management system voltage detection

Supervisors Procurement Notes

Verify the specific suffix N4T2U against official ABLIC documentation to confirm the exact threshold voltage and packaging details. Ensure compatibility with automotive environmental requirements before procurement. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Supervisors Selection Notes

Select this component when a fixed 4.26V threshold is required for automotive applications. The external delay setting allows flexibility in reset timing without internal adjustments. Consider the SC-82AB-4 package size for space-constrained PCB layouts. Verify that the open-drain output interface matches the downstream logic requirements.

Supervisors Part Context

This part belongs to the S-19101xxxA series, which are voltage detectors specifically engineered for automotive use. The series is characterized by its ability to operate reliably at elevated temperatures and its support for external delay time configuration, distinguishing it from standard industrial voltage supervisors.

Supervisors Replacement Considerations

Direct substitutes within the S-19101xxxA series may be available with different threshold voltages or delay configurations. Verify pinout compatibility and electrical specifications before substitution. Consult ABLIC's official cross-reference tools for validated alternatives.
