MAX6316LUK46BY+

Supervisors Overview

The MAX6316LUK46BY+ is a microprocessor supervisory circuit from the MAX6316–MAX6322 family, designed to monitor power supplies and processor activity. It features a fixed reset threshold voltage of 4.6V with an overvoltage threshold of 4.699V. The device operates within a supply voltage range up to 5.5V and consumes only 10µA of quiescent current. It provides an active-low push-pull reset output with a 200ms reset delay time. Integrated features include a watchdog timer and manual reset input. The component is housed in a compact SOT-23-5 surface-mount package and supports operation across an industrial temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Integrates watchdog timer functionality for monitoring microprocessor activity alongside voltage supervision
• Includes manual reset input capability for system control flexibility
• Features factory-trimmed fixed reset threshold voltages ensuring precise supervision without external components
• Designed to ignore fast negative transients on VCC while maintaining valid resets down to 1V

Supervisors Applications

• Monitoring power supplies in digital systems requiring reliable reset generation
• Supervising microprocessor activity via integrated watchdog timer
• Industrial control applications operating within extended temperature ranges

Supervisors Procurement Notes

Verify the specific suffix 'BY' against official Analog Devices documentation, as standard listings often utilize 'CX', 'CY', or 'DW'. Confirm availability status, as this specific variant may be discontinued or subject to limited supply constraints. Ensure the ordering information matches the exact threshold voltage and package type required for your design implementation.

Supervisors Selection Notes

Select this component when a fixed 4.6V threshold is required for single-supply monitoring. The inclusion of both watchdog and manual reset features makes it suitable for complex digital systems. Consider the SOT-23-5 package size for space-constrained designs. Verify that the 200ms reset delay meets the timing requirements of the target microprocessor or logic circuit.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin µP supervisory circuits manufactured by Maxim Integrated (now Analog Devices). The family offers various combinations of reset outputs, watchdog timers, and manual reset inputs. These devices are characterized by low power consumption and miniature packaging, targeting portable and industrial electronics where reliability and board space are critical factors.

Supervisors Replacement Considerations

Check for other variants within the MAX6316 series with different threshold voltages if the 4.6V setting is not strictly required. Cross-reference with MAX6317 or MAX6318 if open-drain or bidirectional outputs are needed instead of push-pull. Verify pinout compatibility before substituting with other 5-pin supervisor ICs.
