MAX6316LUK31DZ+T

Supervisors Overview

The MAX6316LUK31DZ+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors a single voltage input with a fixed threshold of 3.1 V and an overvoltage threshold of 3.126 V. The device features a manual reset input, a watchdog timer, and an active-low push-pull output. It operates within a supply voltage range up to 5.5 V and consumes only 10 µA of quiescent current. The reset delay time is specified at 200 ms. The component is housed in a compact SOT-23-5 surface-mount package and supports operation across an extended industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system fault detection alongside voltage supervision
• Includes a manual reset input for external control of the reset state
• Provides an active-low push-pull output driver for direct logic interfacing
• Operates with ultra-low quiescent current consumption suitable for battery-powered designs

Supervisors Applications

• Portable electronic devices requiring extended battery life
• Industrial control systems operating in harsh thermal environments
• Embedded microprocessor systems needing reliable power-on reset sequences
• Consumer electronics utilizing low-voltage digital logic

Supervisors Procurement Notes

Verify the obsolete status and limited availability before design finalization. Confirm RoHS compliance details through official documentation. Ensure the SOT-23-5 footprint matches your PCB layout constraints. Check for alternative lead-free packaging options if required by regional regulations. Validate that the 3.1 V threshold aligns precisely with your target supply rail specifications.

Supervisors Selection Notes

Select this component when a fixed 3.1 V threshold is required without adjustable potentiometers. Choose it for applications demanding both voltage supervision and watchdog functionality in a minimal footprint. Consider it for designs where low standby current is critical for power efficiency. Verify compatibility with the active-low output polarity required by the downstream logic interface.

Supervisors Part Context

This part belongs to the MAX6316 series of uPower Supervisors designed for monitoring single-rail power supplies. It shares functional similarities with other Maxim Integrated supervisors but distinguishes itself through the combination of watchdog capabilities and manual reset inputs. The series targets cost-sensitive applications requiring robust system protection in small packages.
