DS1818-10/T&R

Supervisors Overview

The DS1818-10/T&R is a single-channel voltage supervisor from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It features a threshold voltage of 2.88V and provides an active-low reset signal with a minimum timeout of 100ms. The device utilizes an open-drain or open-collector output and supports manual pushbutton reset functionality. It operates within a temperature range of -40°C to +85°C and is housed in a TO-92-3 through-hole package.

Supervisors Feature Summary

• Provides simple power-on reset and manual reset capabilities via integrated pushbutton support
• Features an open-drain or open-collector active-low output for flexible interfacing
• Includes a watchdog timer function for system monitoring

Supervisors Applications

• Microprocessor system supervision
• Power supply monitoring
• Battery backup switching circuits

Supervisors Procurement Notes

Verify the specific suffix designation carefully, as the requested model uses a T&R suffix which typically indicates tape and reel packaging, while datasheets often list this part in TO-92-3 through-hole packages. Confirm availability status directly with the manufacturer or authorized distributors, as some variants in this series may be discontinued or have limited stock. Ensure the package type matches your PCB design requirements before ordering.

Supervisors Selection Notes

Select this component when a low-cost, single-supply voltage monitor with manual reset capability is required. The 2.88V threshold makes it suitable for 3.3V systems. Consider the TO-92-3 package if through-hole mounting is preferred over surface-mount alternatives like the SOT-23-3 versions available in the same family.

Supervisors Part Context

This part belongs to the DS1818 EconoReset family, designed for cost-sensitive applications requiring basic supervisory functions. It is distinct from higher-performance monitors like the DS1819 or DS1814, offering simplified features such as a fixed threshold and basic watchdog timing without complex programmability.

Supervisors Replacement Considerations

Compatible substitutes include other DS1818 variants with different thresholds (e.g., DS1818-20) or packages (e.g., DS1818R), provided the voltage threshold and package type are compatible with the design.
