MAX6307UK28D2-T

Supervisors Overview

The MAX6307UK28D2-T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with an active low, open-drain output type and a reset delay time of 1.4 ms. The device operates within a supply voltage range of 1 V to 5.5 V and consumes 8 uA of operating supply current. It utilizes a 5-pin SOT-23 package measuring 2.9 mm in length and 1.1 mm in height. The component lacks manual reset, watchdog timers, and battery backup switching capabilities.

Supervisors Feature Summary

• Monitors more than one power supply for system integrity
• Asserts system reset if monitored supplies fall outside programmed thresholds
• Suitable for portable applications due to low supply current

Supervisors Applications

• Monitoring 5V and 3.3V supplies in personal computer systems
• Portable electronic device power supervision
• Microprocessor system reset generation

Supervisors Procurement Notes

Verify the specific suffix D2 against official Maxim Integrated documentation to confirm the exact threshold voltage configuration. Ensure the ordering part number matches the required input monitoring specifications. Confirm RoHS compliance status and lead-free designation as indicated in the manufacturer's datasheet before finalizing procurement orders.

Supervisors Selection Notes

Select this component when dual-input voltage supervision is required for microprocessor systems. Consider the 1.4 ms reset delay and 8 uA quiescent current for power-sensitive designs. Verify that the SOT-23-5 package dimensions fit the available PCB space. Ensure the operating temperature range meets the application requirements.

Supervisors Part Context

This device belongs to the MAX6305–MAX6313 family of CMOS microprocessor supervisory circuits. These ICs are engineered to monitor multiple power rails simultaneously. The family is characterized by low power consumption and compact packaging, making them ideal for space-constrained portable electronics and standard computing platforms requiring reliable power management.

Supervisors Replacement Considerations

Consult the official MAX6307 datasheet for confirmed substitute part numbers within the same series. Verify pin compatibility and electrical parameters before substituting.
