DS1818-10

Supervisors Overview

The DS1818-10 is a single-channel voltage supervisor from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It provides simple reset and power-on reset functions with an open-drain or open-collector output that asserts low. The device monitors one input voltage against a threshold of 2.88V. It features a minimum reset timeout of 100ms and operates within a temperature range of -40°C to +85°C. The component is available in surface-mount SOT-23-3 packages.

Supervisors Feature Summary

• Provides simple reset and power-on reset functionality for monitored voltage rails
• Features an active-low output signal compatible with open-drain or open-collector configurations
• Includes a guaranteed minimum reset timeout period to ensure stable system initialization

Supervisors Applications

• Microcontroller power supply supervision
• Embedded system voltage monitoring
• Digital logic circuit reset management

Supervisors Procurement Notes

Verify the specific package variant when ordering, as the base model may be available in through-hole TO-92-3 or surface-mount SOT-23-3 configurations. Confirm the suffix indicates the correct tolerance and packaging format required for your assembly process. Cross-reference the manufacturer part number with distributor catalogs to ensure availability of the exact pinout and electrical specifications needed for your design.

Supervisors Selection Notes

Select this component when a basic, cost-effective voltage supervision solution is required without complex watchdog or battery backup features. Ensure the 2.88V threshold aligns with your system's operating voltage requirements. Consider the SOT-23-3 package if space constraints exist, or the TO-92-3 for through-hole prototyping. Verify that the open-drain output interface matches your microcontroller's reset input requirements.

Supervisors Part Context

This part belongs to the DS1818 family of EconoReset supervisors, designed for applications requiring reliable power management without excessive complexity. The series offers various threshold voltages and package options to suit different system architectures. As a legacy Maxim Integrated product now under Analog Devices, it remains a standard choice for fundamental voltage monitoring tasks in industrial and consumer electronics.

Supervisors Replacement Considerations

Direct substitutes include other single-channel supervisors from the same family, such as the DS1818R-10+T&R for surface-mount applications or the DS1818-20/T&R for alternative thresholds. Ensure replacement parts maintain the same output type and reset timeout characteristics to preserve system compatibility.
