MAX6316LUK46BY-T

Supervisors Overview

The MAX6316LUK46BY-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.2V to 5.5V and features a fixed reset threshold voltage of 4.6V. The device provides a manual reset input and includes an integrated watchdog timer with a timeout period of 1.4 seconds. It utilizes a push-pull active-low reset output and is housed in a compact SOT-23-5 surface-mount package. The component supports an extended industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates a manual reset input for system-initiated resets alongside automatic power-on supervision.
• Includes a built-in watchdog timer to monitor processor activity and prevent software lockups.
• Features a low-power design suitable for battery-operated applications.

Supervisors Applications

• Microprocessor power supply monitoring in embedded systems
• Watchdog timer implementation for digital controllers
• Battery-powered portable electronic devices

Supervisors Procurement Notes

Verify the exact suffix 'BY' against official manufacturer documentation, as standard Maxim part numbers typically utilize different alphanumeric codes for temperature and packaging variations. Confirm RoHS compliance status and current production lifecycle stage directly with Analog Devices or authorized distributors before procurement planning.

Supervisors Selection Notes

Select this component when a fixed 4.6V threshold is required for single-supply monitoring. Ensure the application benefits from the combination of manual reset capability and watchdog functionality within a five-pin footprint. Verify that the 1.4-second watchdog timeout aligns with the system's clock frequency and processing requirements.

Supervisors Part Context

This device belongs to the MAX6316–MAX6322 family of 5-pin microprocessor supervisory circuits. These components are designed to monitor power supplies and ensure reliable system startup by providing precise reset signals based on factory-trimmed voltage thresholds.

Supervisors Replacement Considerations

Cross-reference with other MAX6316 variants featuring different reset thresholds or output types if the specific 4.6V level or manual reset feature does not match the target design requirements.
