RS811-3.08YA4

Overview

The RS811-3.08YA4 is a bidirectional supervisor IC from Runic Technology, designed for monitoring a single voltage rail. It features a threshold voltage of 3.08V and operates within a supply voltage range of 3.21V to 5.5V. The device provides a low-active reset signal with a fixed timeout period of 200ms. It is housed in a compact SOT-143 package and supports surface mount mounting. The component is rated for an operating temperature range of -40°C to +125°C, ensuring reliability in industrial environments.

Feature Summary

• Bidirectional output capability for flexible system integration
• Manual reset input functionality for controlled initialization
• Single-channel voltage monitoring with precise threshold detection

Applications

• Embedded systems requiring reliable power supervision
• Industrial control units operating in wide temperature ranges
• Consumer electronics needing compact voltage monitoring solutions

Procurement Notes

Verify the exact suffix YA4 corresponds to the SOT-143 package and specific threshold requirements. Confirm that the bidirectional output aligns with your circuit design needs. Ensure compatibility with the specified 3.21V to 5.5V operating range. Check for any specific handling instructions regarding the surface-mount package during assembly processes.

Selection Notes

Select this component when a single voltage rail requires supervision with a 3.08V threshold. It is suitable for applications demanding bidirectional interface capabilities. Consider the SOT-143 package size for space-constrained designs. Verify that the 200ms timeout meets the system's reset timing requirements.

Part Context

This part belongs to the RS811 series of supervisors by Runic Technology. The series includes variants with different threshold voltages, such as 2.63V and 4.00V options. These devices are commonly used in microcontroller-based systems to ensure stable operation under varying power conditions.

Replacement Considerations

Direct substitutes include other RS811 variants like RS811-2.63YA4 or RS811-4.00YA4 if threshold adjustments are acceptable. Cross-reference pinouts and electrical characteristics carefully before substitution.
