DS1830AU+T&R

Supervisors Overview

The DS1830AU+T&R is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for monitoring voltage sequences and providing manual reset functionality. It operates within an input voltage range of up to 5.5 V and features a threshold voltage of 3.3 V with an accuracy of 20%. The device supports two monitored inputs and delivers active low, open drain outputs. It includes a reset delay time of 75 ms and consumes a working supply current of 25 uA. The component functions reliably across a temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Provides manual reset sequence pushbutton functionality for system control
• Features dual monitored inputs for comprehensive power supervision
• Delivers active low open drain output signals for interface compatibility

Supervisors Applications

• Voltage sequencer applications requiring precise timing control
• Systems utilizing manual reset mechanisms for safe startup
• Supervisory circuits monitoring multiple power rails

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm package type and thermal characteristics. Ensure that the ordering information matches the required operating temperature range and output configuration. Cross-reference the part number with authorized distributor lists to confirm availability status and compliance with regional restrictions. Confirm RoHS status through certified declarations prior to integration into final assemblies.

Supervisors Selection Notes

Select this component when a supervisory circuit with manual reset capability and dual input monitoring is required. Consider the 75 ms reset delay and 20% threshold accuracy for timing-sensitive designs. Evaluate the 25 uA supply current consumption against power budget constraints. Verify compatibility with the 3.3 V threshold and 5.5 V maximum input voltage for the target application environment.

Supervisors Part Context

This part belongs to the DS1830 series of supervisory circuits from Maxim Integrated, now part of Analog Devices. The series focuses on voltage sequencing and reset management for embedded systems. The AU variant specifies the package and temperature grade, distinguishing it from other pinout or performance options within the broader product family designed for industrial and commercial applications.

Supervisors Replacement Considerations

Consult official substitution guides for direct equivalents within the same product line. Verify functional compatibility regarding threshold voltages and reset delays before replacing.
