DS1834AX/T&R

Supervisors Overview

The DS1834AX/T&R is a dual-channel voltage supervisor IC from the Analog Devices / Maxim Integrated portfolio. It provides open-drain or open-collector reset outputs for monitoring two independent power rails. The device features manual reset functionality via an integrated pushbutton input, allowing system recovery without external components. It operates within a supply voltage range of 1.02V to 5.5V and supports industrial temperature ranges. The component is supplied in tape-and-reel packaging for automated surface-mount assembly.

Supervisors Feature Summary

• Dual-channel voltage supervision with configurable thresholds
• Integrated manual reset pushbutton input
• Open-drain or open-collector reset output configuration

Supervisors Applications

• Multi-supply embedded systems requiring redundant power monitoring
• Industrial control units needing manual system recovery
• Automotive electronics with strict voltage supervision requirements

Supervisors Procurement Notes

Verify the specific suffix AX against official datasheets to confirm threshold voltages and package type. Confirm availability status as distribution channels may list limited stock. Ensure RoHS compliance documentation matches current manufacturing standards. Cross-reference pinouts with target PCB layout specifications before integration.

Supervisors Selection Notes

Select this component when dual independent voltage rails require simultaneous supervision. The integrated pushbutton simplifies hardware design by eliminating external reset switches. Verify that the required reset delay times align with system startup sequences. Consider the open-drain output compatibility with downstream logic levels.

Supervisors Part Context

This part belongs to the DS1834 family of EconoReset supervisors. It complements single-channel variants by offering dual monitoring capabilities in a compact footprint. The series is designed for cost-sensitive applications requiring reliable power management without complex external circuitry.

Supervisors Replacement Considerations

DS1834S+ serves as a direct functional substitute within the same product family. Verify pin compatibility and threshold voltage specifications before substitution. Ensure the replacement variant meets the same environmental operating conditions.
