RS706-2.63YK

Overview

The RS706-2.63YK is a power monitoring and reset circuit manufactured by Runic Technology, housed in an SOP-8 package. It features a precise voltage monitor set at 2.63V with a low quiescent current of 40μA maximum. The device operates within a supply voltage range of 1.0V to 5.5V and includes a manual reset input compatible with TTL/CMOS logic. It provides a fixed 160ms reset pulse width and ensures the RESET output remains active down to 1.0V. An independent watchdog timer with a typical timeout of 1.6 seconds is integrated for system protection.

Feature Summary

• Integrated independent watchdog timer for system fault recovery
• Compatible manual reset input supporting TTL and CMOS standards
• Low power consumption suitable for battery-operated applications
• Guaranteed valid reset signal at minimum operating voltage

Applications

• Battery-powered electronic devices requiring voltage supervision
• Microcontroller-based systems needing reliable reset generation
• Industrial equipment utilizing independent watchdog functionality
• Portable consumer electronics prioritizing low standby current

Procurement Notes

Verify that the specific suffix YK corresponds to the SOP-8 package configuration required for your PCB layout. Confirm the exact threshold voltage matches the 2.63V specification for your target application. Ensure compatibility with the 1.0V to 5.5V operating range. Check for any specific handling requirements associated with the green packaging material mentioned in official documentation.

Selection Notes

Select this component when a dedicated voltage supervisor with an integrated watchdog is required. It is suitable for designs needing a guaranteed reset state at very low voltages. Consider the 40μA maximum current draw for efficiency-critical projects. The SOP-8 package offers a balance between pin count and board space constraints.
