MAX6307UK28D1-T

Supervisors Overview

The MAX6307UK28D1-T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with active low, open-drain outputs and a reset delay time of 1.4 ms. The device operates within a supply voltage range up to 5.5 V and consumes an operating supply current of 8 uA. It lacks manual reset, watchdog timer, battery backup switching, and chip enable signals. The component is housed in a SOT-23-5 package and supports surface mount installation.

Supervisors Feature Summary

• Monitors multiple power supplies for system integrity
• Provides active low open-drain reset output
• Integrates manual reset input capability

Supervisors Applications

• Microprocessor reset supervision
• Multi-rail power monitoring systems
• Embedded controller protection circuits

Supervisors Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status and lead-free specifications prior to integration. Check for restricted availability or limited distribution channels as indicated by supplier listings. Ensure the specific variant matches the required threshold voltages and package dimensions for the target PCB layout.

Supervisors Selection Notes

Select this component when dual-input voltage supervision is required with low quiescent current consumption. The open-drain output allows flexible logic level interfacing. Verify that the 1.4 ms reset delay aligns with system startup timing requirements. Consider the SOT-23-5 footprint constraints during mechanical design phase.

Supervisors Part Context

Part of the MAX6305–MAX6313 series of 5-pin programmable reset ICs. Designed for applications requiring monitoring of more than one power supply. Manufactured by Maxim Integrated, now part of Analog Devices Inc. The UK28D1 suffix indicates specific threshold voltage configurations within the family.

Supervisors Replacement Considerations

Consult official cross-reference lists for direct replacements. Verify compatibility of threshold voltages, output polarity, and package dimensions before substitution.
