MAX6316MUK46AY+

Supervisors Overview

The MAX6316MUK46AY+ is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors a single power supply input with a fixed threshold voltage of 4.6V and an overvoltage threshold of 4.699V. The device features an active low, push-pull reset output and includes both a watchdog timer and manual reset functionality. It operates within a supply voltage range up to 5.5V, consumes 10µA of quiescent current, and has a reset delay time of 200ms. The component is housed in a SOT-23-5 package and supports an operating temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates a watchdog timer for monitoring microprocessor activity alongside voltage supervision.
• Provides manual reset capability via a dedicated input pin for system control.
• Features an active low, push-pull reset output for direct interface compatibility.

Supervisors Applications

• Digital systems requiring microprocessor activity monitoring
• Portable applications utilizing low-power supervisory circuits
• Systems needing manual reset intervention capabilities

Supervisors Procurement Notes

Verify authenticity through authorized distributors as this component may be subject to limited availability or obsolescence status. Confirm the specific suffix codes match the required electrical parameters, particularly the 4.6V threshold and industrial temperature grade. Check for RoHS compliance documentation and ensure the SOT-23-5 package matches the design footprint requirements before finalizing procurement.

Supervisors Selection Notes

Select this part when a fixed 4.6V threshold is required for a single-supply application. The inclusion of a watchdog timer distinguishes it from basic supervisors. Ensure the active low push-pull output aligns with the target logic levels. Consider the 10µA quiescent current for battery life calculations and verify that the 200ms reset delay meets the system startup timing constraints.

Supervisors Part Context

This component belongs to the MAX6316–MAX6322 family of 5-pin µP supervisory circuits. These devices are designed to monitor power supplies and processor activity in digital systems. The family offers various combinations of reset outputs and features like watchdog timers and manual resets, available in multiple factory-trimmed threshold voltages.

Supervisors Replacement Considerations

Other parts in the MAX6316 series with different threshold voltages (e.g., MAX6316MUKxx) may serve as functional substitutes if the voltage level is adjusted. Verify that any replacement maintains the same SOT-23-5 package, active low push-pull output type, and integrated watchdog/manual reset features.
