MAX6307UK46D3

Supervisors Overview

The MAX6307UK46D3 is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features a factory-set reset threshold voltage of 4.63V and supports inputs for both 5V and 3.3V systems. The device provides an active-low, open-drain reset output with a manual reset input capability. It operates within a supply voltage range up to 5.5V and consumes only 8µA of supply current. The component is housed in a compact SOT-23-5 package suitable for surface-mount applications.

Supervisors Feature Summary

• Monitors multiple power supply inputs simultaneously
• Includes manual reset input functionality
• Provides active-low open-drain reset signal
• Operates with low supply current consumption

Supervisors Applications

• Portable computer systems
• Multivoltage embedded control systems
• Personal computer power monitoring
• Intelligent instruments requiring dual-voltage supervision

Supervisors Procurement Notes

Verify the specific suffix D3 against official Analog Devices documentation to confirm the exact reset timeout delay and threshold tolerance. Ensure the ordering part number matches the required package variant and temperature range specifications before procurement.

Supervisors Selection Notes

Select this component when simultaneous monitoring of distinct voltage rails such as 5V and 3.3V is required. The fixed 4.63V threshold suits applications needing precise supervision without external programming components. Consider the SOT-23-5 footprint for space-constrained portable designs.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 family of 5-pin, multiple-input programmable reset ICs. These devices are engineered to ignore fast transients on monitored supplies while asserting a system reset if any supply falls outside its programmed threshold. The series targets portable and battery-powered equipment.

Supervisors Replacement Considerations

Cross-reference with other MAX6307 variants or MAX6305/MAX6306 series parts if different threshold voltages or reset delays are needed. Verify pin compatibility and package dimensions when substituting with similar supervisory circuits from the same manufacturer.
