DS1810R-15-U+

Supervisors Overview

The DS1810R-15-U+ is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It functions as a voltage monitor with a fixed threshold of 4.62V, designed to detect power supply anomalies. The device features an active-low open-drain reset output and supports manual reset functionality via an external pushbutton. It operates within a supply voltage range of 1.0V to 5.5V and includes a programmable reset pulse width. The component is housed in a surface-mount SOT-23-3 package and is rated for industrial temperature operation from -40°C to +85°C.

Supervisors Feature Summary

• Monitors system voltage against a fixed 4.62V threshold
• Provides active-low open-drain reset signal
• Supports manual reset input for system control
• Operates at low supply voltages down to 1.0V

Supervisors Applications

• Embedded system power supervision
• Microcontroller reset management
• Battery-powered device monitoring
• Industrial control unit protection

Supervisors Procurement Notes

Verify the specific suffix 'U+' indicates the lead-free RoHS-compliant variant. Confirm the 'R' designation aligns with the required SOT-23-3 package configuration. Check current availability status as distribution may be limited or restricted. Ensure the fixed 4.62V threshold matches the target application's voltage requirements before procurement.

Supervisors Selection Notes

Select this component when a fixed voltage threshold near 4.62V is required without the need for adjustable settings. It is suitable for applications needing manual reset capability alongside automatic power-fail detection. Consider the low quiescent current and small SOT-23-3 footprint for space-constrained designs. Verify compatibility with the system's operating voltage range of 1.0V to 5.5V.
