MAX6430ORUS-T

Overview

The MAX6430ORUS-T is a single-supply, low-power voltage supervisor manufactured by Analog Devices Inc. (Maxim Integrated). It operates within an input voltage range of 1.25V to 5.5V and provides a reset output with a selectable threshold voltage between 1.63V and 4.75V in 0.1V increments. The device features a manual reset input, open-drain or push-pull reset output configuration, and a watchdog timer with a timeout period ranging from 140ms to 1.4s. It functions reliably across an industrial temperature range of -40°C to +85°C and is housed in an ultra-small 6-pin SOT-23 package.

Feature Summary

• Provides precise voltage supervision with adjustable threshold detection for system stability
• Integrates a programmable watchdog timer to prevent software lockups
• Supports both open-drain and push-pull reset output configurations for flexible interfacing

Applications

• Portable consumer electronics requiring low standby current
• Battery-powered embedded systems needing brown-out protection
• Industrial control units utilizing microcontroller reset management

Procurement Notes

Verify the specific suffix ORUS-T against official datasheets to confirm pinout and packaging details. Confirm RoHS compliance status as manufacturing processes may vary. Check for obsolescence notices or lifecycle changes directly from Analog Devices documentation before procurement planning.

Selection Notes

Select this component when a compact footprint and low quiescent current are critical. Ensure the required reset delay and watchdog timeout periods align with the target application's timing constraints. Verify that the supply voltage range covers the minimum operating voltage of the monitored circuit.

Part Context

This part belongs to the MAX6430 family of voltage supervisors designed for single-supply applications. It complements other Maxim Integrated power management solutions by offering reliable monitoring in space-constrained environments. The series is commonly used alongside battery chargers and DC-DC converters in portable devices.

Replacement Considerations

Consult official Analog Devices cross-reference tools for verified equivalents. Ensure any substitute matches the SOT-23-6 package and supports the required voltage thresholds and watchdog functionality.
