MAX6307UK46D3-T

Supervisors Overview

The MAX6307UK46D3-T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It operates within a supply voltage range up to 5.5V and features a fixed reset threshold of 4.38V. The device provides an active low, open-drain output with a manual reset input. It consumes 15µA of supply current and functions across a temperature range of -40°C to +85°C. Packaged in a compact SOT-23-5 format, it asserts a system reset if monitored supplies fall outside programmed thresholds.

Supervisors Feature Summary

• Monitors multiple power supplies for system integrity
• Includes manual reset input capability
• Immune to short supply transients
• Operates with low supply current consumption

Supervisors Applications

• Portable computers
• Personal computer systems monitoring 5V and 3.3V rails
• Controllers and intelligent instruments
• Multivoltage embedded control systems

Supervisors Procurement Notes

Verify the specific suffix D3 against official Analog Devices documentation to confirm the exact factory-set threshold voltage and timeout delay. Ensure the package type matches the required PCB footprint. Confirm RoHS compliance status for the specific manufacturing batch before integration into final designs.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltage rails is required in space-constrained designs. The fixed threshold eliminates external resistor networks. Consider the open-drain output compatibility with the target logic family. Verify that the 15µA quiescent current meets the system's power budget requirements.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 series of 5-pin, multiple-input programmable reset ICs. These devices are engineered for portable applications due to their small package and low current draw. They are specifically designed to ignore fast transients on monitored supplies while guaranteeing reset validity down to 1V.

Supervisors Replacement Considerations

Cross-reference with other MAX630x variants such as MAX6307UK31D3+T or MAX6309EUK46D3+T. Verify that alternative parts match the 4.38V threshold and SOT-23-5 package. Ensure functional equivalents support the same manual reset and multi-supervision capabilities.
