RS803-4.65YSF3

Overview

The RS803-4.65YSF3 is a supply voltage supervisor manufactured by Runic Technology, designed to monitor power rails in electronic systems. It features an open-drain reset output and operates within a supply voltage range of 1.0V to 5.5V. The device has a fixed threshold voltage of 4.65V, ensuring precise monitoring for applications requiring stable power supervision. Packaged in a compact SOT-23-3 form factor, it offers low supply current consumption, making it suitable for portable equipment where energy efficiency is critical.

Feature Summary

• Provides reliable power supply monitoring with a fixed threshold voltage
• Features an open-drain reset output for flexible interface compatibility
• Designed for low power consumption to support battery-operated devices

Applications

• Portable electronic equipment requiring power supervision
• Battery-powered systems needing voltage monitoring
• General purpose analog circuits requiring reset signals

Procurement Notes

Verify the specific threshold voltage (4.65V) matches your system requirements. Confirm the SOT-23-3 package dimensions fit your PCB layout. Ensure the open-drain output configuration aligns with your microcontroller or logic input specifications. Check for any RoHS compliance documentation if required for your manufacturing process.

Selection Notes

Select this component when a fixed 4.65V supervision threshold is needed. Consider the low current consumption for battery life optimization. The SOT-23-3 package is ideal for space-constrained designs. Verify that the open-drain output can be properly pulled up in your circuit design.

Part Context

This part belongs to the RS803 series of supply voltage supervisors from Runic Technology. The series includes various threshold voltages to accommodate different power rail monitoring needs. The RS803-4.65YSF3 specifically targets applications requiring a 4.65V trip point. It is part of Runic's portfolio of general-purpose analog ICs focused on performance and efficiency.

Replacement Considerations

Check for other RS803 variants with different threshold voltages if 4.65V is not suitable. Compare pinouts and electrical characteristics with other open-drain reset supervisors. Ensure substitute parts offer similar low current consumption and operate within the same voltage range.
