DS1810R-10/T&R

Supervisors Overview

The DS1810R-10+T&R is a supervisory circuit from the EconoReset family, designed for monitoring single voltage inputs in surface-mount applications. It operates within a supply voltage range up to 5.5 V and features a push-pull output configuration. Key electrical parameters include a threshold voltage of 4.35 V, an overvoltage threshold of 4.49 V, and a reset delay time of 100 ms minimum. The device draws a typical operating supply current of 40 uA and maintains an accuracy of 2.5%. It supports power-fail detection and functions reliably across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides simple reset or power-on-reset functionality with a push-pull output stage.

Supervisors Applications

• Monitoring microprocessor supply voltages
• Battery-powered system supervision
• Portable electronic device power management

Supervisors Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and sourcing channels before procurement.

Supervisors Selection Notes

Select this component when a low-cost, single-channel supervisor with a push-pull output is required. Consider the 4.35 V threshold and 100 ms reset delay for compatibility with system timing requirements. Evaluate the 40 uA supply current for battery life constraints and verify the SOT-23-3 package fits the PCB layout constraints.

Supervisors Part Context

This part belongs to the Maxim Integrated EconoReset series, which offers cost-effective supervisory solutions. The DS1810 variant specifically utilizes a push-pull output, distinguishing it from open-drain counterparts in the same family. It is manufactured by Analog Devices Inc., continuing the legacy of Maxim Integrated's power management portfolio.

Supervisors FAQ

What is the output type of the DS1810R-10+T&R?

The DS1810R-10+T&R features a push-pull (totem pole) output, unlike other variants in the series that may use open-drain outputs.

Does this component support manual reset?

No, the DS1810R-10+T&R does not include a manual reset input; it relies on automatic power-on-reset and voltage monitoring triggers.
