MAX6307UK28D4-T

Supervisors Overview

The MAX6307UK28D4-T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with a fixed 2.8V threshold and adjustable precision. The device provides an active-low, open-drain reset output with a minimum timeout of 1.12 seconds. It operates within a supply voltage range up to 5.5V and is housed in a compact SOT-23-5 package.

Supervisors Feature Summary

• Monitors two independent power supply rails simultaneously
• Provides precise voltage supervision with a fixed 2.8V threshold
• Features an active-low open-drain reset signal for system control

Supervisors Applications

• Personal computer systems monitoring 5V and 3.3V rails
• Portable electronic devices requiring low supply current
• Embedded systems needing multi-voltage supervision

Supervisors Procurement Notes

Verify the specific suffix D4 corresponds to the 2.8V threshold configuration. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated. Ensure the SOT-23-5 package matches the design requirements. Check for lead-free compliance if required by assembly standards.

Supervisors Selection Notes

Select this component when dual-rail supervision is necessary. The fixed 2.8V threshold suits applications requiring precise monitoring of lower voltage rails. The small SOT-23-5 footprint is ideal for space-constrained designs. Consider the 1.12s minimum timeout for system stability requirements.

Supervisors Part Context

Part of the MAX6305–MAX6313 series of CMOS microprocessor supervisory circuits. These devices are engineered for monitoring multiple power supplies in portable and desktop applications. The series emphasizes low power consumption and compact packaging to support modern electronic design constraints.

Supervisors Replacement Considerations

Check for other MAX6307 variants with different thresholds or timeout values. Verify pinout compatibility with existing PCB layouts. Ensure electrical specifications match the target application's voltage and current requirements.
