MAX6316LUK45BX+

Supervisors Overview

The MAX6316LUK45BX+ is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of up to 5.5 V and features a fixed reset threshold voltage of 4.5 V with an overvoltage threshold of 4.599 V. The device provides an active low, push-pull output and includes both a watchdog timer and manual reset functionality. It consumes 10 uA of operating current and offers a reset delay time of 200 ms. The component is housed in a SOT-23-5 package and supports surface mount installation across a temperature range of -40 C to +125 C.

Supervisors Feature Summary

• Integrates a watchdog timer for monitoring processor activity alongside a manual reset input for system control.
• Provides a fixed reset threshold voltage of 4.5 V with high accuracy for reliable power supervision.
• Features an active low, push-pull output driver compatible with various digital logic families.

Supervisors Applications

• Microprocessor power supply monitoring in embedded systems
• Watchdog timer implementation for system stability
• Manual reset circuit integration for user-initiated restarts

Supervisors Procurement Notes

Verify the exact suffix configuration against the manufacturer's official datasheet to ensure correct threshold voltage and package type. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary. Ensure the ordering part number matches the specific electrical requirements and packaging format needed for your design.

Supervisors Selection Notes

Select this component when a fixed 4.5 V threshold is required for single-supply monitoring. The inclusion of both watchdog and manual reset features makes it suitable for complex digital systems requiring robust fault handling. Consider the SOT-23-5 package size for space-constrained designs and verify that the 10 uA quiescent current meets the system's power budget constraints.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin μP supervisory circuits. The family offers various combinations of reset outputs and thresholds ranging from 2.5 V to 5 V. The MAX6316 variant specifically focuses on providing essential supervision functions with integrated watchdog and manual reset capabilities in a compact form factor.

Supervisors Replacement Considerations

Check for other MAX6316 variants with different threshold voltages if the 4.5 V setting is not optimal. Verify pinout compatibility with alternative supervisory ICs from the same manufacturer before substitution.
