DS1810R-5/T&R

Supervisors Overview

The DS1810R-5/T&R is a single-channel voltage supervisor from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range up to 5.5V and features a fixed threshold of 4.62V. The device provides a push-pull/totem pole output with an active-low reset signal. It includes a minimum reset timeout of 100ms and functions as a simple reset or power-on reset circuit. The component is available in a surface-mount SOT-23-3 package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides simple reset and power-on reset functionality for monitored voltage rails
• Features a push-pull or totem pole output configuration for direct drive capability
• Includes a guaranteed minimum reset timeout period to ensure stable system initialization

Supervisors Applications

• Power supply monitoring in embedded systems
• Microcontroller reset generation during power-up sequences
• Voltage supervision in industrial control equipment

Supervisors Procurement Notes

Verify the specific suffix designation when ordering, as variations such as DS1810R-5+T&R-W indicate obsolete status while other tape-and-reel variants remain active. Confirm the manufacturer source, as Analog Devices and Maxim Integrated branding may appear interchangeably on legacy documentation. Ensure the selected packaging format matches the required production line specifications for surface-mount assembly processes.

Supervisors Selection Notes

Select this component when a fixed 4.62V threshold is required for 5V logic systems. The push-pull output distinguishes it from open-drain alternatives like the DS1811 series. Consider the SOT-23-3 footprint for space-constrained designs. Verify that the 100ms minimum timeout aligns with the target microcontroller's startup requirements before finalizing the bill of materials.

Supervisors Part Context

This part belongs to the DS1810 family of voltage supervisors designed for cost-sensitive applications. It serves as a fundamental building block for power management circuits where manual reset inputs or watchdog timers are unnecessary. The EconoReset series focuses on providing essential reset generation without complex programmability.

Supervisors Replacement Considerations

The DS1810R-5+T&R is listed as obsolete in some distributor records. Potential functional substitutes within the same family include the DS1812R-5+T&R, which offers similar threshold characteristics but with an active-high reset output.
