RS809-2.93YSF3

Overview

The RS809-2.93YSF3 is a power supply monitor supervisor manufactured by Runic Technology, housed in an SOT-23-3 package. It features a push-pull output and monitors a single voltage threshold of 2.93V. The device operates within a voltage range of 1.0V to 5.5V with a maximum low power consumption of 40µA. It ensures the RESET signal remains valid at VCC = 1.0V and provides a fixed reset pulse width of 200ms.

Feature Summary

• Monitors power supply voltage with a precise threshold of 2.93V
• Maintains active reset state down to 1.0V input voltage
• Generates a standardized 200ms reset pulse duration

Applications

• Embedded system power supervision
• Microcontroller reset circuitry
• Battery-powered device monitoring

Procurement Notes

Verify the manufacturer datasheet for exact electrical characteristics and thermal limits. Confirm the SOT-23-3 package dimensions match your PCB footprint requirements. Ensure the 2.93V threshold aligns with your specific circuit design needs before procurement.

Selection Notes

Select this component when a fixed 2.93V monitoring threshold is required. The low quiescent current suits battery-operated designs. Verify compatibility with the target logic levels and ensure the 200ms delay meets system startup timing constraints.

Part Context

This part belongs to the RS809 series of supervisory circuits from Runic Technology. These devices are designed for reliable power management in industrial and consumer electronics. The series offers various voltage thresholds to accommodate different system requirements while maintaining consistent performance characteristics.

Replacement Considerations

Check for direct pin-compatible alternatives with identical 2.93V thresholds and SOT-23-3 packaging. Verify that substitute components offer comparable reset pulse widths and operating voltage ranges to ensure circuit functionality remains unchanged.
