MAX6309UK46D3+T

Supervisors Overview

The MAX6309UK46D3+T is a CMOS microprocessor supervisory circuit designed to monitor power supplies. It features a fixed reset threshold voltage of 4.63V and includes a manual reset input. The device operates within a supply voltage range up to 5.5V and consumes low supply current, making it suitable for portable applications. It asserts a system reset if the monitored supply falls outside the programmed threshold and ignores fast transients. The component is housed in a SOT-23-5 package.

Supervisors Feature Summary

• Monitors power supply voltage levels with a fixed threshold
• Includes manual reset input capability
• Designed to ignore fast transients on monitored supplies

Supervisors Applications

• Personal computer systems monitoring 5V and 3.3V supplies
• Portable electronic devices requiring low supply current
• Microprocessor supervisory circuits

Supervisors Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to confirm lead-free status and specific threshold voltage. Confirm availability through authorized distributors as stock levels vary. Ensure the SOT-23-5 package matches your PCB footprint requirements before ordering.

Supervisors Selection Notes

Select this component when a fixed 4.63V threshold is required for single-supply monitoring. It is appropriate for designs needing manual reset functionality and transient immunity. Consider the SOT-23-5 package size for space-constrained portable applications.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 series of 5-pin multiple-input programmable reset ICs from Maxim Integrated. These devices are specifically engineered to monitor more than one power supply, asserting a reset if any monitored supply exceeds its programmed threshold.

Supervisors Replacement Considerations

Other parts in the MAX6305–MAX6313 series may serve as substitutes if different threshold voltages or package options are acceptable. Verify pinout compatibility and electrical specifications before substitution.
