MAX6316LUK31BX/V+T

Supervisors Overview

The MAX6316LUK31BX/V+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.2V to 5.5V and features a fixed reset threshold voltage of 3.1V. The device integrates a watchdog timer with a timeout period of approximately 1.4 seconds and includes a manual reset input for system control. It provides an active-low, push-pull output and consumes a maximum supply current of 10µA. The component is available in a compact SOT-23-5 package and supports industrial temperature ranges up to +125°C.

Supervisors Feature Summary

• Integrates a watchdog timer with automatic timeout reset functionality
• Includes a dedicated manual reset input pin for user-initiated system resets
• Features low power consumption suitable for battery-operated applications
• Provides active-low push-pull output driver

Supervisors Applications

• Portable electronic devices requiring reliable power supervision
• Microprocessor systems needing watchdog protection against software faults
• Battery-powered equipment where low quiescent current is critical
• Industrial control units operating in extended temperature environments

Supervisors Procurement Notes

Verify the specific suffix (BX or V) against the manufacturer's official datasheet to confirm exact threshold tolerances and packaging specifications. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the ordering part number matches the required temperature grade and package variant before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed 3.1V threshold is required alongside integrated watchdog and manual reset capabilities. Compare the 10µA supply current against other supervisors if ultra-low power is the primary constraint. Verify that the SOT-23-5 package dimensions fit the target PCB layout and that the active-low output polarity aligns with the connected microprocessor reset pin requirements.

Supervisors Part Context

This part belongs to the MAX6316 family of uPower Supervisors designed for monitoring single power supplies. The series offers various factory-programmed thresholds and package options. The MAX6316 specifically targets applications requiring combined voltage supervision, watchdog timing, and manual reset control in a minimal footprint, distinguishing it from simpler voltage detectors lacking timer functions.

Supervisors Replacement Considerations

Check for direct substitutes within the MAX6316 series with different threshold voltages if the 3.1V setting is not optimal. Consider the MAX6319 or MAX6320 families for similar functionality but potentially different package styles or additional features like chip enable inputs. Always verify pin compatibility and electrical parameters before substituting.
