MAX6306UK47D3

Supervisors Overview

The MAX6306UK47D3 is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It asserts a system reset if any monitored supply falls outside the programmed threshold, making it suitable for personal computer systems monitoring 5V and 3.3V rails. The device features a manual reset input and ignores fast transients on monitored supplies. It operates within a maximum supply voltage of 5.5V and consumes low supply current. The component is housed in a compact SOT-23-5 package.

Supervisors Feature Summary

• Monitors multiple power supply inputs to assert system reset when thresholds are exceeded
• Includes a manual reset input for direct control override
• Immune to fast transients on monitored supply lines
• Operates with low supply current suitable for portable applications

Supervisors Applications

• Personal computer systems monitoring 5V and 3.3V supplies
• Portable computers and battery-powered equipment
• Multivoltage embedded control systems

Supervisors Procurement Notes

Verify the specific suffix D3 against official Analog Devices documentation to confirm the exact factory-set reset threshold voltage and timeout delay characteristics. Confirm RoHS compliance status and lead-free designation as indicated by the plus sign in related part numbers. Check current lifecycle status and availability through authorized distributors, as this series may have limited stock or obsolescence notices.

Supervisors Selection Notes

Select this component when precise, factory-programmed reset thresholds are required without external resistors. Ensure the fixed threshold matches the target supply rail. Verify that the manual reset feature meets system requirements. Consider the operating temperature range and package size constraints for the final design.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 family of 5-pin, multiple-input, programmable reset ICs from Maxim Integrated. These devices are designed for microprocessor supervision in environments requiring reliable power monitoring. The UK suffix typically denotes specific threshold voltages and package variations within the broader product line.

Supervisors Replacement Considerations

Consult official datasheets for cross-reference options within the MAX6305–MAX6313 series. Verify pinout compatibility and electrical parameters such as reset threshold and supply current before substituting.
