MAX6351LRUT

Overview

The MAX6351LRUT is a dual-channel microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors two independent voltage rails to ensure system reliability. The device features an open-drain or open-collector reset output that asserts low when monitored voltages fall below their respective thresholds. It operates within a supply voltage range of 1.2V to 6V and provides a fixed reset timeout period. The component is available in a compact SOT-23-6 surface-mount package, suitable for space-constrained portable and industrial applications requiring robust power management supervision.

Feature Summary

• Dual-channel voltage monitoring capability for independent power rails
• Open-drain/reset output with active-low assertion logic
• Fixed reset timeout duration ensures stable system initialization
• Compact SOT-23-6 surface-mount packaging for efficient board layout

Applications

• Portable electronic devices requiring multi-voltage supervision
• Industrial control systems needing reliable power fault detection
• Embedded computing platforms with multiple power domains

Procurement Notes

Verify the specific suffix (e.g., +T) for tape-and-reel configuration. Confirm availability status as some variants may be discontinued. Ensure compatibility with existing PCB footprint and voltage thresholds during integration.

Selection Notes

Select based on required monitored voltage thresholds and package constraints. Verify operating temperature range matches application environment. Check if open-drain output interface aligns with downstream logic requirements.

Part Context

Part of the MAX635x family of dual/triple voltage supervisors. Designed for general-purpose power monitoring in embedded systems. Shares common pinout and functional architecture with related models like MAX6350 and MAX6358 series components.

Replacement Considerations

MAX6351LRUT+T is the standard tape-and-reel variant. Cross-reference with MAX6351 series members for similar dual-supervisor functions. Verify threshold voltages match original design specifications before substitution.
