DS1816R-20/T&R

Supervisors Overview

The DS1816R-20/T&R is a single-channel voltage supervisor from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It monitors one input voltage with a threshold of 3.06V and provides a low-active reset signal via an open-drain or open-collector output. The device features a minimum reset timeout of 100ms and operates within a temperature range of -40°C to +85°C. It is housed in a surface-mount SOT-23-3 package.

Supervisors Feature Summary

• Provides simple power-on reset functionality for single-supply systems
• Features an open-drain or open-collector active-low reset output
• Includes a guaranteed minimum reset timeout period

Supervisors Applications

• Microprocessor system supervision
• Portable equipment power monitoring
• Battery-powered circuit protection

Supervisors Procurement Notes

Verify the specific suffix 'T&R' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer designation as Analog Devices Inc. or Maxim Integrated, as ownership transitions may affect documentation sources. Ensure the component matches the SOT-23-3 footprint and electrical specifications required for the target design before finalizing procurement.

Supervisors Selection Notes

Select this component for applications requiring a cost-effective, single-channel voltage monitor with a fixed threshold. The SOT-23-3 package suits space-constrained designs. Verify that the open-drain output configuration aligns with the downstream logic requirements and that the 3.06V threshold meets the system's voltage supervision needs.

Supervisors Part Context

This part belongs to the DS1816 family of voltage supervisors, designed for basic power management tasks. The 'R' suffix typically denotes the SOT-23-3 package variant, while the numeric code specifies the trip point voltage. These devices are engineered for simplicity and reliability in consumer and industrial electronics.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the same EconoReset family, such as variants with different voltage thresholds or manual reset capabilities. Ensure any substitute maintains the SOT-23-3 package and open-drain output characteristics.
