DS1818R-10-U

Supervisors Overview

The DS1818R-10-U is a single-channel voltage supervisor from the EconoReset series by Analog Devices Inc./Maxim Integrated. It features an open-drain or open-collector output with active-low reset functionality. The device monitors one input channel with a threshold voltage of 2.88V and provides a minimum reset timeout of 100ms. Designed for surface-mount installation in SOT-23-3 packages, it operates within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides simple reset and power-on reset functions for monitored circuits
• Features open-drain or open-collector output configuration
• Delivers low-active reset signal upon undervoltage detection

Supervisors Applications

• Embedded system power management
• Microcontroller circuit supervision
• Portable electronic device protection

Supervisors Procurement Notes

Verify the package suffix against official documentation, as 'U' typically denotes tube packaging while 'T&R' indicates tape and reel. Confirm that the specific ordering suffix matches the required manufacturing format for your production line. Cross-reference the manufacturer part number with authorized distributor catalogs to ensure authenticity and traceability before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with a fixed 2.88V threshold is required. Ensure the application environment stays within the specified -40°C to +85°C operating temperature range. Verify that the open-drain output interface aligns with the downstream logic requirements of the target microcontroller or system design.

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.
