MAX6316MUK46AY-T

Supervisors Overview

The MAX6316MUK46AY-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors power supplies in digital systems with a fixed reset threshold voltage of 4.6V and an overvoltage threshold of 4.699V. The device features a manual reset input, a watchdog timer, and an active-low push-pull output. It operates within a supply voltage range up to 5.5V and consumes 10uA of quiescent current. The component supports a reset delay time of 200ms and functions across a temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Monitors power supplies and microprocessor activity in digital systems
• Includes integrated watchdog timer for system reliability
• Features manual reset input for user-initiated control
• Provides active-low push-pull reset output

Supervisors Applications

• Microprocessor power supply monitoring
• Digital system supervision
• Watchdog timer implementation
• Manual reset circuit integration

Supervisors Procurement Notes

Verify the exact suffix 'AY' against official manufacturer documentation to confirm specific factory-trimmed parameters. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary. Ensure the SOT-23-5 package matches your PCB footprint requirements before ordering.

Supervisors Selection Notes

Select this component when a fixed 4.6V threshold is required for single-supervision applications. The inclusion of both a watchdog timer and manual reset makes it suitable for robust digital systems. Consider the -40°C to +125°C operating range for industrial environments. Verify that the active-low push-pull output stage meets the interface requirements of the target microprocessor.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin microprocessor supervisory circuits. These devices are designed to monitor power supplies and ensure system stability through various reset output combinations and timeout periods. The family offers multiple factory-trimmed threshold voltages and packaging options to suit diverse design needs.

Supervisors Replacement Considerations
