MAX6316LUK29CX

Supervisors Overview

The MAX6316LUK29CX+ is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in a SOT-23-5 surface-mount package. It features a fixed threshold voltage of 2.93 V and an overvoltage threshold of 2.974 V for single-input monitoring. The device provides an active low, push-pull output with a manual reset capability and includes an integrated watchdog timer. Key electrical parameters include a maximum supply voltage of 5.5 V, a reset delay time of 200 ms, and an operating current of 10 uA. Accuracy is specified at 1.5%, with a power dissipation of 571 mW. It operates within a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Integrates a watchdog timer function for system reliability monitoring alongside voltage supervision capabilities.
• Provides manual reset functionality allowing user-initiated system resets independent of voltage thresholds.
• Features an active low, push-pull output structure suitable for direct interfacing with digital logic inputs.

Supervisors Applications

• Microprocessor systems requiring voltage supervision and watchdog protection
• Portable equipment utilizing battery backup scenarios
• Industrial control systems operating in extreme temperature environments

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to limited availability status. Confirm RoHS compliance details and specific lot traceability requirements before procurement. Ensure the ordering suffix matches the exact pinout and functional specifications required for your design implementation. Cross-reference datasheet revisions to guarantee compatibility with existing firmware and hardware constraints.

Supervisors Selection Notes

Select this component when a fixed 2.93 V threshold is required for single-supply monitoring applications. Consider the 10 uA operating current for low-power designs and the -40°C to +125°C temperature range for industrial use. Verify that the SOT-23-5 package fits the PCB layout constraints and that the active low output polarity aligns with the target microcontroller reset input requirements.

Supervisors Part Context

This part belongs to the MAX6316 series of voltage supervisory circuits from Maxim Integrated, now part of Analog Devices. The series offers various threshold voltages and package options to suit different embedded system needs. The LUK29 variant specifically targets applications needing precise supervision around the 3V logic level, combining reset generation with watchdog timing in a compact form factor.

Supervisors Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains the same SOT-23-5 footprint, 2.93 V threshold, and watchdog functionality. Verify pin compatibility and output drive characteristics to prevent signal integrity issues during migration.

Supervisors FAQ

Does the MAX6316LUK29CX+ support adjustable threshold voltages?

No, the MAX6316LUK29CX+ has a fixed threshold voltage of 2.93 V and does not support external adjustment of the reset threshold.

What is the purpose of the watchdog timer in this device?

The integrated watchdog timer monitors the system software execution; if the processor fails to toggle the watchdog input within a specified period, the device asserts a reset to recover the system.
