MAX6317HUK46CY-T

Supervisors Overview

The MAX6317HUK46CY-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. The device operates within a supply voltage range up to 5.5V and features a manual reset input for system control. It utilizes a SOT-23-5 surface-mount package and supports an operating temperature range from -40°C to +125°C. Key electrical characteristics include a typical quiescent current of 3µA, a reset delay time of 1.4ms, and an overvoltage threshold of 2.538V.

Supervisors Feature Summary

• Integrates watchdog timer functionality and manual reset input for comprehensive system monitoring
• Provides flexible design options through configurable push/pull, open-drain, and bidirectional reset outputs
• Features factory-trimmed reset threshold voltages ensuring precise power supply supervision

Supervisors Applications

• Monitoring power supplies in embedded digital systems
• Supervising microprocessor activity in industrial controllers
• Ensuring system stability in automotive electronic modules

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Check for obsolescence notices or lifecycle changes as availability may be restricted. Ensure packaging specifications match handling requirements for surface mount assembly processes.

Supervisors Selection Notes

Select this component when a fixed 4.6V threshold is required for single-supply monitoring. Consider the integrated watchdog and manual reset features if system reliability depends on active fault detection. Verify that the SOT-23-5 package fits the available PCB real estate. Ensure the operating temperature range meets the environmental conditions of the target application.

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 timeout periods. The suffix '46' indicates the specific 4.6V threshold voltage setting. The 'C' denotes the commercial/industrial temperature grade, while 'Y' specifies the tape-and-reel packaging format.

Supervisors Replacement Considerations

Cross-reference with other MAX631x series variants for different threshold voltages or output configurations. Verify pin compatibility and functional equivalence before substituting with generic supervisor ICs.
