S-80819CNPF-B8ETFU

Supervisors Overview

The S-80819CNPF-B8ETFU is a high-precision voltage detector developed using CMOS process technology by ABLIC. It features a fixed detection threshold voltage of 1.9 V with an accuracy of ±2.0%. The device operates within a supply voltage range of 0.65 V to 5.0 V for thresholds ≤1.4 V, and 0.95 V to 10.0 V for thresholds ≥1.5 V. It consumes a typical current of 1.3 μA at low detection voltages. The component provides an Nch open-drain active-low output and includes built-in hysteresis characteristics. It is housed in the compact SNT-4A-4 package.

Supervisors Feature Summary

Supervisors Procurement Notes

Verify the specific suffix B8E against official ABLIC documentation to confirm the exact threshold voltage and tape-and-reel specifications. Ensure the ordering code matches the required SNT-4A-4 package variant. Cross-reference the manufacturer's latest datasheet for any product change notifications or environmental compliance updates prior to final procurement.

Supervisors Selection Notes

Select this component when a precise 1.9 V detection threshold is required for systems operating up to 10 V. The low quiescent current makes it ideal for battery life extension. Verify that the Nch open-drain output configuration aligns with the downstream logic interface requirements. Confirm that the operating temperature range meets the application's environmental constraints.

Supervisors Part Context

This part belongs to the S-808xxC series of super-small package high-precision voltage detectors. The series utilizes CMOS technology to achieve high accuracy and low power consumption. The S-80819CNPF-B8ETFU specifically denotes the 1.9 V threshold variant in the SNT-4A-4 package, designed for space-constrained applications requiring reliable voltage supervision.

Supervisors Replacement Considerations

Check ABLIC's official cross-reference lists for direct replacements. Consider other S-808xxC variants if different threshold voltages are acceptable. Verify pinout compatibility before substituting with generic voltage detectors.
