DS1812R-10+T&R

Supervisors Overview

The DS1812R-10+T&R is a voltage monitor integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 4.35 V. The device provides a high-active reset signal with a minimum reset timeout of 100 ms. It utilizes a push-pull/totem pole output configuration and is housed in an SOT-23-3 package. The component supports surface mount installation and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides simple reset or power-on reset functionality for single-channel monitoring
• Features a push-pull output stage delivering a high-active reset signal
• Includes a guaranteed minimum reset timeout period of 100 ms

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix and tape-and-reel packaging designation when ordering. Confirm that the manufacturer designation matches Analog Devices Inc. or Maxim Integrated. Ensure the SOT-23-3 package type aligns with the PCB footprint requirements. Check for RoHS compliance documentation if required by the manufacturing process.

Supervisors Selection Notes

Select this component when a high-active reset signal is required for systems operating near 5 V. The fixed 4.35 V threshold suits applications where the supply voltage must remain above this level for proper operation. The push-pull output allows direct interfacing with digital logic without requiring external pull-up resistors.

Supervisors Part Context

This part belongs to the EconoReset series, designed for cost-effective voltage supervision. It serves as a fundamental building block for ensuring system stability during power transitions. The SOT-23-3 package offers a compact solution for space-constrained designs requiring reliable power management.

Supervisors Replacement Considerations

Consult official datasheets for pin-compatible alternatives within the same series. Verify that any substitute maintains the 4.35 V threshold and high-active reset polarity. Ensure the replacement supports the required 100 ms timeout and SOT-23-3 form factor.
