MAX6307UK30D4-T

Supervisors Overview

The MAX6307UK30D4-T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with a threshold voltage of 3.0V and an active low, open-drain output. The device operates within a supply voltage range up to 5.5V and includes a reset delay time of 1570 ms. It is housed in a compact SOT-23-5 package suitable for surface mount applications.

Supervisors Feature Summary

• Monitors two independent power supply inputs simultaneously
• Provides active low open-drain reset signal generation
• Configurable threshold voltage for specific application requirements

Supervisors Applications

• Personal computer system power monitoring
• Portable electronic device supervision
• Multi-rail embedded system reset management

Supervisors Procurement Notes

Verify the exact suffix D4-T against official Maxim Integrated documentation to confirm the specific threshold voltage and packaging details. Ensure compatibility with existing board layouts due to the SOT-23-5 footprint. Confirm lead times and availability through authorized distributors as this component may have limited stock or obsolescence status.

Supervisors Selection Notes

Select this component when dual-supervision is required for critical power rails. The open-drain output allows for wired-OR configurations. Consider the 1570 ms delay for systems requiring extended stabilization periods before reset assertion. Verify that the 3.0V threshold aligns with the minimum operating voltage of the monitored loads.

Supervisors Part Context

Part of the MAX6305–MAX6313 family of 5-pin multiple-input programmable reset ICs. Designed for low supply current consumption of 15µA, making it suitable for battery-powered portable applications. Manufactured by Maxim Integrated, now part of Analog Devices Inc.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the MAX6307 series with different threshold voltages if the 3.0V setting is unsuitable. Verify electrical characteristics match for any cross-referenced components from other manufacturers.
