RS706-4.00YK

Overview

The RS706-4.00YK is a bidirectional supervisor IC from Runic Technology, housed in an 8-SOIC package. It monitors supply voltage with a fixed threshold of 4.00V and operates within a range of 1.0V to 5.5V. The device features a low power consumption of 40µA maximum and ensures the RESET output remains active at VCC=1.0V. It includes a 160ms reset pulse width and an independent watchdog timer with a typical timeout of 1.6 seconds. The component supports manual reset inputs compatible with TTL/CMOS levels and functions across a temperature range of -40°C to 125°C.

Feature Summary

• Integrated independent watchdog timer for system reliability
• Bidirectional output interface for flexible circuit integration
• Compatible manual reset input supporting TTL/CMOS logic levels

Applications

• Battery-powered systems requiring low voltage monitoring
• Microcontroller-based embedded systems needing reset supervision
• Industrial control units operating in extreme temperatures

Procurement Notes

Verify the specific suffix YK confirms the 4.00V threshold and SOP-8 packaging. Confirm RoHS compliance status if required by your manufacturing standards. Ensure the supplier provides original manufacturer documentation to validate the bidirectional output capability and watchdog specifications against generic RS706 variants.

Selection Notes

Select this model when a fixed 4.00V monitoring threshold is required for systems operating up to 5.5V. The bidirectional output allows connection to both microcontroller reset pins and other supervisory circuits. Consider the 1.6s watchdog timeout for applications requiring longer fault detection periods compared to standard supervisors.

Part Context

This component belongs to the RS706 series of supervisor and reset ICs designed for voltage monitoring and system protection. The series offers various fixed voltage thresholds to suit different power rails. The RS706-4.00YK specifically targets applications needing precise supervision around the 4V level, combining reset generation with watchdog functionality in a compact surface-mount package.

Replacement Considerations

Check for RS706-2.93YK or RS706-3.08YK if different voltage thresholds are acceptable. Verify pin compatibility with existing PCB layouts before substituting.
