DS1817R-5+T&R

Supervisors Overview

The DS1817R-5+T&R is a power management supervisor IC from Analog Devices that monitors voltage levels and provides reset control in electronic systems. It operates within a supply voltage range up to 5.5 V, featuring an active high output type suitable for direct logic interfacing. The device includes a fixed reset delay time of 150 ms to ensure stable power-up conditions. It functions reliably across a temperature range from -40 C to +85 C with an accuracy of 2.5%. The component is housed in a compact SOT-23-3 package designed for surface mount installation.

Supervisors Feature Summary

• Monitors system voltage levels to detect power failures
• Provides active high reset signal for reliable logic interfacing
• Ensures stable power-up sequences with fixed delay timing

Supervisors Applications

• Embedded system power supervision
• Microcontroller reset circuitry
• Portable device power management

Supervisors Procurement Notes

Verify the specific suffix T&R indicates reel packaging when sourcing. Confirm the manufacturer designation matches Analog Devices Inc./Maxim Integrated for authenticity. Check RoHS compliance details against current regulatory requirements. Ensure the SOT-23-3 package footprint aligns with your PCB design constraints before finalizing procurement.

Supervisors Selection Notes

Select this component when an active high output is required for the reset line. The 5V threshold specification suits standard 5V logic systems. Consider the 2.5% accuracy and 150ms delay for timing-sensitive applications. The SOT-23-3 package offers space efficiency for compact designs requiring single-channel voltage monitoring.

Supervisors Part Context

This part belongs to the DS1817 series of EconoReset supervisors. The series focuses on cost-effective voltage monitoring solutions. Other variants in the family offer different thresholds or output polarities. The DS1817R-5+T&R specifically targets 5V system applications with active high outputs.

Supervisors Replacement Considerations

Check for DS1817R-10+T&R if a higher threshold is needed. Verify compatibility with DS1817-5/T&R for through-hole alternatives. Ensure pinout alignment when substituting with other single-channel supervisors.
