RS803-2.93YSF3

Overview

The RS803-2.93YSF3 is a single-channel supervisory circuit manufactured by Runic Technology, designed to monitor power supply voltages in electronic systems. It operates within an ambient temperature range of -40°C to 125°C and utilizes a surface-mount SOT-23-3 package (also identified as TO-236-3 or SC-59). The device features an open-drain or open-collector output configuration, suitable for interfacing with various logic families. With a threshold voltage of 2.93V, it provides reliable reset signal generation for monitored circuits.

Feature Summary

• Single-channel voltage monitoring capability
• Open-drain or open-collector output interface
• Extended industrial operating temperature range

Applications

• Power supply monitoring in embedded systems
• Microcontroller reset circuit generation
• Industrial control unit supervision

Procurement Notes

Verify the manufacturer designation as Runic Technology or Jiangsu Runic Technology Co., Ltd. when sourcing components. Confirm the specific suffix YSF3 corresponds to the SOT-23-3 package variant. Ensure compatibility with the required 2.93V threshold specification for your application design. Check for active status availability through authorized distributors.

Selection Notes

Select this component when a single-channel supervisor with a 2.93V threshold is required. Consider the SOT-23-3 package size for space-constrained designs. Verify that the open-drain/open-collector output aligns with your system's pull-up requirements. Ensure the operating temperature range meets your environmental specifications.
