MAX6307UK35D3

Supervisors Overview

The MAX6307UK35D3+T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It operates within a supply voltage range of up to 5.5V and features a fixed reset threshold of 3.5V. The device provides an active low, open-drain output with a manual reset input capability. It functions in temperatures from -40°C to +85°C and consumes only 15µA of supply current. Packaged in a compact SOT-23-5 surface-mount case, it asserts a system reset if any monitored supply falls outside the programmed threshold.

Supervisors Feature Summary

• Monitors multiple power supply inputs simultaneously
• Asserts system reset when monitored voltages exceed thresholds
• Includes manual reset input for controlled system recovery

Supervisors Applications

• Personal computer systems monitoring 5V and 3.3V rails
• Portable applications requiring low supply current
• Microprocessor supervisory circuits

Supervisors Procurement Notes

Verify the specific suffix (e.g., +T) for tape-and-reel packaging availability. Confirm RoHS compliance status as indicated by the plus sign in the part number. Check manufacturer documentation for lead-free specifications and moisture sensitivity levels before integration into production assemblies.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltage rails is required. Ensure the fixed 3.5V threshold aligns with the target supply voltage. Consider the open-drain output configuration for compatibility with downstream logic levels and pull-up requirements.

Supervisors Part Context

Part of the MAX6305–MAX6313 series of 5-pin programmable reset ICs. Designed specifically to ignore fast transients on monitored supplies. Manufactured by Analog Devices / Maxim Integrated using CMOS technology for low power consumption and small package size suitability.

Supervisors Replacement Considerations

Cross-reference with other MAX6307 variants having different threshold voltages or output configurations. Verify pinout compatibility with SOT-23-5 packages before substitution.
