DS1811-15

Supervisors Overview

The DS1811-15 is a simple reset and power-on reset integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a temperature range of -40°C to +85°C (TA). The device features a threshold voltage of 4.13V and provides an active-low reset output via an open-drain or open-collector configuration. The minimum reset timeout duration is specified as 100ms. This component is packaged in TO-226-3 or TO-92-3 formats for through-hole installation.

Supervisors Feature Summary

• Provides reliable system reset functionality triggered by power-on events or voltage drops below the specified threshold.
• Features an active-low reset signal output compatible with standard digital logic interfaces.
• Designed for robust operation across industrial temperature ranges.

Supervisors Applications

• Microcontroller system supervision
• Power management circuit protection
• Embedded system initialization control

Supervisors Procurement Notes

Verify the specific package variant (TO-226-3 or TO-92-3) required for your PCB layout, as both are listed under this part number. Confirm that the 4.13V threshold aligns with your system's supply voltage requirements. Check current availability status, as this component may be subject to limited supply or discontinuation notices from the manufacturer.

Supervisors Selection Notes

Select this component when a basic, low-cost reset solution is needed for systems operating between -40°C and +85°C. Ensure the 100ms minimum timeout meets your microcontroller's startup time requirements. Verify compatibility with the target supply voltage relative to the 4.13V threshold. Consider the through-hole mounting style if surface mount options are not available for this specific revision.

Supervisors Part Context

The DS1811 series belongs to Maxim Integrated's family of simple reset supervisors. These devices are designed to monitor supply voltages and generate reset signals to ensure proper system initialization. The DS1811-15 specifically denotes a version with a 4.13V threshold, distinguishing it from other variants in the series with different trip points.
