MAX6834VXRD3+

Supervisors Overview

The MAX6834VXRD3+T is a single-channel voltage supervisory circuit in an SC-70-3 package. It monitors one input with a threshold of 1.575 V and overvoltage detection at 1.62 V. The device features an active-low, open-drain reset output with a fixed delay of 210 ms. It operates on supply voltages up to 3.6 V with a quiescent current of 16 uA across the -40°C to +85°C industrial temperature range.

Supervisors Feature Summary

• Provides reliable system supervision for low-voltage power rails by asserting a reset signal when supply voltage drops below the preset threshold.
• Features an open-drain active-low output compatible with various logic families without requiring external pull-up components for basic operation.
• Eliminates the need for external adjustments or discrete components through fixed internal thresholds and timeout delays.

Supervisors Applications

• Monitoring microprocessor (µP) power supplies
• Digital system voltage supervision
• Battery-powered device power management

Supervisors Procurement Notes

Verify component authenticity and datasheet revisions before integration. Confirm RoHS compliance status and lead times with authorized distributors. Check for obsolescence notices as this part may have limited availability. Ensure packaging specifications match assembly requirements.

Supervisors Selection Notes

Select this component for applications requiring a compact, low-power supervisor for single-rail monitoring. Consider the fixed 1.575 V threshold and 210 ms delay against system timing requirements. Evaluate the open-drain output configuration for interface compatibility with the target logic family.

Supervisors Part Context

This device belongs to the MAX6832–MAX6840 series of ultra-low-voltage SC70 voltage detectors and µP reset circuits. These devices are designed to monitor low-voltage power supplies in microprocessor and digital systems, offering reliability and cost savings by eliminating external components.

Supervisors FAQ

Does the MAX6834VXRD3+T include a manual reset pin?

No, this specific variant does not feature a manual reset input; it relies solely on automatic power-supply monitoring.

What is the reset delay time for this component?

The reset delay time is fixed at 210 ms after the supply voltage rises above the reset threshold.
