MAX6306UK30D2-T

Supervisors Overview

The MAX6306UK30D2-T is a single-input voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.2V to 5.5V and features a fixed reset threshold voltage of 3.0V. The device provides an active-low, open-drain output and includes a manual reset input for system control. It incorporates a watchdog timer with a timeout period of 60ms and offers a reset delay time of 60ms. Packaged in a compact SOT-23-5 format, it supports surface-mount installation.

Supervisors Feature Summary

• Integrates a watchdog timer with a 60ms timeout period for automated fault recovery
• Features a manual reset input allowing direct user intervention for system resets
• Provides an active-low, open-drain output compatible with standard logic interfaces
• Designed to monitor a single power supply rail with a fixed 3.0V threshold

Supervisors Applications

• Microprocessor system supervision
• Portable electronic devices requiring low standby current
• Battery-powered equipment monitoring
• Personal computer systems

Supervisors Procurement Notes

Verify the exact suffix against official documentation, as variations such as +T or D3 may indicate different manufacturing revisions or compliance statuses. Confirm availability through authorized distributors, as this specific part number may be subject to limited stock or discontinuation. Ensure the selected variant matches the required operating temperature range and package specifications for your design.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog functionality is required. The fixed 3.0V threshold suits applications monitoring 3.3V rails. Consider the SOT-23-5 package for space-constrained designs. Verify that the active-low open-drain output aligns with the target microcontroller's reset pin requirements and pull-up configuration.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 family of CMOS microprocessor supervisory circuits. These devices are engineered to monitor multiple power supplies, though individual variants like the MAX6306 monitor a single input. They are designed to ignore fast transients on monitored supplies, making them suitable for noisy environments. The family typically offers low supply current and small packages ideal for portable applications.

Supervisors Replacement Considerations

Cross-reference with other MAX6306 variants (e.g., MAX6306UK30D3+T) if lead-free compliance or specific revision differences are critical. Ensure any substitute maintains the same 3.0V threshold, SOT-23-5 package, and watchdog timer functionality.
