MAX6312UK43D3+

Supervisors Overview

The MAX6312UK43D3+T is a CMOS microprocessor supervisory circuit designed to monitor a single power supply. It features a factory-programmed reset threshold voltage of 4.3 V and an overvoltage threshold of 4.408 V. The device operates within a supply voltage range up to 5.5 V and draws a typical operating supply current of 7 µA. It provides a manual reset input and asserts an active-low, push-pull output with a fixed reset delay time of 225 ms. The component is housed in a compact SOT-23-5 package and supports operation across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Monitors a single power supply rail for undervoltage conditions
• Includes a manual reset input for system control
• Provides an active-low, push-pull reset output signal

Supervisors Applications

• Portable electronic devices requiring low standby current
• Battery-powered systems needing precise voltage supervision
• Embedded controllers requiring manual reset capability

Supervisors Procurement Notes

Verify the specific suffix (e.g., +T) against official documentation to confirm packaging format such as reel or cut tape. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the part number matches the exact threshold voltage and package type required for your design specifications before procurement.

Supervisors Selection Notes

Select this component when a single-channel supervisor with a fixed 4.3 V threshold is required. Consider the 7 µA quiescent current for battery efficiency. Verify that the active-low push-pull output interface is compatible with the target microcontroller's reset pin requirements. Ensure the operating temperature range meets the environmental constraints of the application.

Supervisors Part Context

This part belongs to the MAX63xx series of CMOS microprocessor supervisory circuits manufactured by Analog Devices / Maxim Integrated. These devices are engineered to provide reliable reset signals for digital systems. The series offers various threshold voltages and package options to suit different monitoring needs in portable and industrial applications.

Supervisors Replacement Considerations

Check for direct substitutes within the MAX63xx family with identical threshold voltages and output configurations. Verify pinout compatibility if replacing with other SOT-23-5 supervisors. Consult official cross-reference lists for confirmed equivalent part numbers.
