MAX6305UK00D2

Supervisors Overview

The MAX6305UK00D2+T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with adjustable thresholds, typically configured for 3.3V and 5V rails. The device provides an active-low open-drain reset output with a fixed delay of 1.4ms. Operating from a supply voltage up to 5.5V, it draws only 8µA of quiescent current. Packaged in a compact SOT-23-5 footprint, it ignores fast transients on monitored lines.

Supervisors Feature Summary

• Monitors multiple power supply rails simultaneously
• Features adjustable overvoltage threshold detection
• Provides active-low open-drain reset signal
• Designed to ignore fast supply transients

Supervisors Applications

• Personal computer system power monitoring
• Portable electronic devices requiring low current
• Multi-rail embedded system supervision

Supervisors Procurement Notes

Verify the exact suffix against official Analog Devices documentation, as variations like D2 or D3 may indicate specific factory programming or packaging configurations. Confirm RoHS compliance status and lead-free designation directly from the manufacturer datasheet before procurement. Ensure the ordering part number matches the required threshold settings and package type.

Supervisors Selection Notes

Select this component when simultaneous monitoring of distinct voltage levels such as 3.3V and 5V is required. The adjustable threshold capability allows customization for specific supply requirements. Consider the low 8µA operating current for battery-powered applications. Verify that the SOT-23-5 package fits the board space constraints and that the open-drain output interface is compatible with the target logic family.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 series of 5-pin, multiple-input programmable reset ICs manufactured by Maxim Integrated, now part of Analog Devices. These circuits are specifically engineered for microprocessor systems needing robust power supervision across several voltage domains within a minimal physical footprint.

Supervisors Replacement Considerations

Consult the official MAX6305 datasheet for verified pin-compatible alternatives within the same series. Substitutes must maintain identical input count, output polarity, and package dimensions to ensure functional equivalence without board redesign.
