DS1812R-5+T&R

Supervisors Overview

The DS1812R-5+T&R is a single-channel voltage supervisor from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a temperature range of -40°C to +85°C and utilizes a SOT-23-3 surface-mount package. The device features a push-pull/totem pole output with an active-high reset signal. Key electrical parameters include a monitored voltage threshold of 4.62V and a minimum reset timeout duration of 100ms.

Supervisors Feature Summary

• Provides simple reset or power-on reset functionality for monitored circuits
• Features a push-pull or totem pole output configuration
• Generates an active-high reset signal upon detecting undervoltage conditions

Supervisors Applications

• Microprocessor system supervision
• Power supply monitoring in embedded systems
• Battery-powered device protection

Supervisors Procurement Notes

Verify the manufacturer designation as Analog Devices Inc./Maxim Integrated when sourcing this component. Confirm the specific suffix T&R indicates tape and reel packaging. Ensure compatibility with the required SOT-23-3 footprint and validate that the 4.62V threshold meets the target circuit's voltage supervision requirements before finalizing procurement.

Supervisors Selection Notes

Select this component when a single-channel supervisor with a fixed 4.62V threshold is required. The SOT-23-3 package offers space efficiency for compact designs. Consider the 100ms minimum reset timeout for applications requiring stable power-up sequencing. Verify that the active-high output logic aligns with the connected microcontroller or processor input specifications.

Supervisors Part Context

This part belongs to the DS1812 family of supervisory circuits. It is designed for cost-sensitive applications requiring basic voltage monitoring. The EconoReset series provides essential protection functions without complex programmability. It serves as a fundamental building block for ensuring reliable operation in digital systems powered by regulated supplies.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio. Verify that any substitute maintains the 4.62V threshold and SOT-23-3 package. Ensure the replacement supports the same operating temperature range and output drive capability.
