MAX6307UK49D3-T

Supervisors Overview

The MAX6307UK49D3-T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It operates within a supply voltage range of 1V to 5.5V and features an active-low, open-drain reset output. The device monitors two inputs with a fixed threshold voltage of 4.9V for the primary channel and 3.3V for the secondary. It includes a programmable reset delay time of 200ms and draws only 8µA of operating supply current. Packaged in a compact SOT-23-5 surface-mount case, it supports industrial temperature ranges from 0°C to +70°C.

Supervisors Feature Summary

• Monitors two independent power supply rails simultaneously
• Provides active-low open-drain reset signal assertion
• Features low quiescent current consumption for portable applications
• Includes programmable reset delay timer functionality

Supervisors Applications

• Personal computer system power monitoring
• Portable electronic device power management
• Multi-rail embedded system supervision
• Battery-powered equipment voltage tracking

Supervisors Procurement Notes

Verify the specific suffix D3 indicates the 4.9V threshold variant when sourcing. Confirm RoHS compliance status as lead-free versions typically carry a plus sign (+). Check manufacturer documentation for exact tape and reel specifications required for automated assembly processes. Ensure the SOT-23-5 footprint matches your PCB design constraints before finalizing procurement orders.

Supervisors Selection Notes

Select this component when dual-supervision is required without manual reset or watchdog features. Compare against other MAX6307 variants based on specific threshold voltage needs and temperature grades. Consider the 8µA current draw advantage over standard supervisors for battery life optimization. Verify that the open-drain output compatibility matches your system logic levels.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 family of multi-input supervisory circuits. These devices are engineered for systems requiring simultaneous monitoring of distinct voltage rails. The series offers various threshold combinations and delay times to suit different application requirements while maintaining a small physical footprint.

Supervisors Replacement Considerations

Check MAX6307UK49D3+T for lead-free equivalent availability. Review MAX6307UK49D4-T if a different reset delay timing is acceptable. Consult MAX6307EUK49D3-T for extended temperature range options if operating conditions exceed commercial limits.
