S-80851CLY-Z2-U

Supervisors Overview

The S-80851CLY-Z2-U is a voltage detector manufactured by ABLIC Inc., designed for monitoring power supply integrity in electronic systems. It operates within a maximum supply voltage of 10 V and features a fixed threshold voltage of 5.1 V with an accuracy of ±2.0%. The device utilizes a CMOS output type configured as active low, providing a reset signal when the monitored voltage drops below the specified threshold. It includes a reset delay time of 60 µs to ensure stable operation during transient conditions. The component supports through-hole installation in a TO-92-3 package and functions reliably across a temperature range from -40 °C to +85 °C.

Supervisors Procurement Notes

Verify the exact threshold voltage and package configuration against the official datasheet before integration. Confirm that the active low CMOS output polarity matches the target microcontroller input requirements. Ensure the operating temperature range meets the environmental specifications of the final application. Cross-reference the manufacturer part number to avoid confusion with similar series variants.

Supervisors Selection Notes

Select this component when a through-hole solution is required for voltage supervision. The 5.1 V threshold suits applications monitoring higher voltage rails compared to lower-voltage CMOS processes. Consider the 60 µs reset delay for timing-sensitive designs. Verify compatibility with the system's maximum supply voltage limit of 10 V. Evaluate the TO-92-3 package constraints regarding board space and thermal management.

Supervisors Part Context

This part belongs to the S-808xxC series of high-precision voltage detectors developed using CMOS technology. The series offers various fixed detection voltages and output configurations to support diverse power management needs. The S-80851 variant specifically targets applications requiring a 5.1 V detection point with robust noise immunity provided by the inherent hysteresis characteristics of the CMOS output stage.

Supervisors Replacement Considerations

Check for other S-808xxC series parts with identical 5.1 V thresholds and TO-92-3 packaging. Verify pinout compatibility if substituting with different manufacturers' voltage detectors. Ensure replacement components maintain the same active low output polarity and reset delay specifications.
