DS1816R-10+T&R

Supervisors Overview

The DS1816R-10+T&R is a microprocessor supervisory circuit from the EconoReset series by Analog Devices Inc./Maxim Integrated. It monitors a single voltage channel with a threshold of 4.35V and an overvoltage threshold of 4.49V. The device features an active low, open-drain reset output with a minimum reset timeout of 150ms. Operating within a supply voltage range up to 5.5V, it maintains accuracy within 2.5%. The component supports surface mount installation in a SOT-23-3 package and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides power-failure detection capabilities for digital systems
• Features an open-drain output compatible with various logic families
• Ensures system stability through defined reset timeout durations

Supervisors Applications

• Monitoring power supplies in embedded digital systems
• Microprocessor supervisory circuits requiring voltage threshold tracking
• Power management units needing reliable reset signal generation

Supervisors Procurement Notes

Verify the specific suffix designation to confirm the exact threshold voltage and output configuration, as variations exist within the family. Ensure compatibility with the target operating temperature range and supply voltage limits. Confirm RoHS compliance status if required by regulatory standards. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and current availability status before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a fixed 4.35V monitoring threshold is required for single-channel supervision. The open-drain output necessitates an external pull-up resistor, which must be sized according to the connected load and desired switching speed. Consider the 150ms reset delay when designing timing-critical sequences. Verify that the SOT-23-3 package fits the available PCB footprint constraints and thermal requirements of the application environment.

Supervisors Part Context

This device belongs to the DS1816 series of supervisory circuits, designed specifically for cost-sensitive applications requiring basic power monitoring. It serves as a simplified alternative to complex multi-channel supervisors, focusing on essential voltage threshold detection and reset generation without additional features like watchdog timers or manual reset inputs.

Supervisors Replacement Considerations

DS1816R-5+T&R offers a different threshold voltage while maintaining similar package and output characteristics.
