DS1810R-15/T&R

Supervisors Overview

The DS1810R-15/T&R is a voltage monitor supervisor circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 4.75 V to 5.25 V and features a fixed threshold voltage of 4.13 V. The device provides an active low, push-pull output signal with a reset delay time of 100 ms minimum. It is housed in a SOT-23-3 surface-mount package and functions across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides power supply supervision via a dedicated monitoring input channel
• Generates system reset signals using a push-pull output stage
• Ensures stable operation through a defined reset delay timer

Supervisors Applications

• Microprocessor system power management
• Embedded controller voltage supervision
• Industrial equipment power integrity monitoring

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Ensure the component meets required environmental operating ranges for the intended deployment environment before integration into final designs.

Supervisors Selection Notes

Select this component when a fixed threshold voltage near 4.13 V is required for standard logic level systems. The push-pull output capability allows direct interfacing with digital inputs without external pull-up resistors, simplifying board layout compared to open-drain alternatives.

Supervisors Part Context

This part belongs to the DS1810 series of EconoReset supervisors designed for cost-sensitive applications. It offers basic voltage monitoring functionality in a compact three-pin package, serving as a fundamental protection element for low-power digital circuits requiring reliable power-on reset sequences.

Supervisors Replacement Considerations

Cross-reference with other DS1810 variants such as DS1810R-10+T&R for different threshold requirements. Verify that substitute components maintain identical package dimensions and output drive capabilities to ensure mechanical and electrical compatibility.
