DS1834U+

Supervisors Overview

The DS1834U+ is a dual voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors two independent power supply rails with threshold voltages of 3.3 V and 5 V. The device features an active low, open-drain output type and includes manual reset capability via a pushbutton input. It operates within a supply voltage range of 1.2 V to 5.5 V and has a reset delay time of 500 ms. The component is housed in an uMAX-8 surface-mount package and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Dual-channel voltage supervision for monitoring multiple power rails simultaneously
• Integrated manual reset functionality allowing user-initiated system resets
• Open-drain output configuration compatible with various logic families

Supervisors Applications

• Embedded systems requiring redundant power supply monitoring
• Industrial control units needing manual reset capabilities
• Consumer electronics with multi-voltage architecture requirements

Supervisors Procurement Notes

Verify the specific suffix designation when ordering, as it may indicate packaging or temperature grade variations. Confirm availability status directly with authorized distributors, as this component may be subject to limited supply conditions. Ensure the selected variant matches the required uMAX-8 package and operating temperature range specifications for your application design.

Supervisors Selection Notes

Select this component when dual voltage monitoring with manual reset is required. Compare against single-channel alternatives if only one rail needs supervision. Verify that the 500 ms reset delay meets system timing requirements. Ensure the open-drain output interface aligns with the downstream logic input specifications.

Supervisors Part Context

This part belongs to the DS1834 series of EconoReset circuits designed for cost-sensitive applications. It shares the uMAX-8 package form factor with other Maxim Integrated supervisory devices but distinguishes itself through dual-channel monitoring and manual reset integration. The series focuses on providing essential power management functions in compact packages.
