DS1817-5/T&R

Supervisors Overview

The DS1817-5+T&R is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, functioning as an EconoReset device with a fixed output threshold of 3.3V. It features a push-pull or totem pole output configuration and is housed in a TO-92-3 package. The component operates as a single-channel supervisor designed to monitor voltage levels and provide reset signals for digital systems.

Supervisors Feature Summary

• Fixed 3.3V output threshold for precise voltage monitoring
• Push-pull or totem pole output stage for robust signal driving
• Single-channel supervision architecture

Supervisors Applications

• Embedded system power supply monitoring
• Microcontroller reset circuitry
• Industrial control voltage supervision

Supervisors Procurement Notes

Verify the specific suffix designation against official datasheets to confirm output polarity and package type. Confirm RoHS compliance status through manufacturer documentation. Ensure the TO-92-3 form factor matches board layout requirements before procurement.

Supervisors Selection Notes

Select this component when a fixed 3.3V threshold is required for system reset logic. The TO-92-3 package suits through-hole applications where space allows. Evaluate the push-pull output capability against load requirements to ensure adequate drive strength for connected logic gates.

Supervisors Part Context

This part belongs to the Maxim Integrated EconoReset family, which provides cost-effective supervisory solutions. These devices are engineered for basic voltage monitoring tasks in consumer and industrial electronics, offering reliable performance without complex programmability.

Supervisors Replacement Considerations

Check for direct equivalents within the DS1817 series with different voltage thresholds if system voltage differs. Verify pinout compatibility with existing PCB footprints before substituting with other supervisor ICs from Analog Devices.
