DS1812-5/T&R

Supervisors Overview

The DS1812-5/T&R is a single-channel voltage supervisor from the EconoReset series by Analog Devices Inc./Maxim Integrated. It provides simple reset and power-fail detection for systems operating within a 4.75V to 5.5V supply range. The device features a fixed threshold of 4.62V and an active-high push-pull output. It includes a minimum reset timeout of 100ms to ensure stable system initialization. Designed for surface-mount applications, it is housed in a compact SOT-23-3 package and operates reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides active-high reset signal generation based on monitored supply voltage levels
• Includes manual reset input capability for user-initiated system recovery
• Features integrated power-fail detection with configurable threshold monitoring

Supervisors Applications

• Microprocessor and microcontroller power supply supervision

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical characteristics and pinout compatibility. Ensure the selected variant matches the required output polarity and package type for your design. Cross-reference the component marking code with the datasheet to prevent counterfeit or mislabeled parts during assembly.

Supervisors Selection Notes

Select this component when a single-channel supervisory circuit with an active-high output is required. It is suitable for designs needing manual reset functionality alongside automatic power-on reset. Consider the SOT-23-3 footprint constraints and the specific 4.62V threshold accuracy requirements relative to the target logic family voltage levels.
