MAX6317HUK46CY+T

Supervisors Overview

The MAX6317HUK46CY+T is a microprocessor supervisory circuit from the MAX6316–MAX6322 family, manufactured by Analog Devices Inc./Maxim Integrated. It monitors power supplies and processor activity in digital systems. The device features a fixed reset threshold voltage of 4.6 V and supports manual reset functionality. It operates within a supply voltage range up to 5.5 V and includes a watchdog timer for system reliability. The component is housed in a compact SOT-23-5 surface-mount package and is rated for an extended industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates watchdog timer and manual reset capabilities for comprehensive system supervision
• Provides factory-trimmed reset threshold voltage for precise monitoring without external components
• Supports multiple output configurations including push-pull and open-drain options

Supervisors Applications

• Microprocessor power supply monitoring in embedded systems
• Watchdog timer implementation for fault recovery in digital circuits
• Manual reset input integration for user-initiated system restarts

Supervisors Procurement Notes

Verify the exact suffix CY against official manufacturer documentation to confirm pinout and electrical characteristics, as suffixes define specific package and thermal variants. Confirm availability status with authorized distributors, as this part may be subject to limited supply or end-of-life restrictions. Ensure compatibility with existing PCB footprint and thermal management requirements before procurement.

Supervisors Selection Notes

Select this component when a fixed 4.6 V threshold is required alongside integrated watchdog and manual reset functions. Compare against other MAX631x variants if different timeout periods or output types are needed. Verify that the SOT-23-5 package fits the design constraints and that the operating temperature range meets the application environment specifications.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin μP supervisory circuits. These devices are designed to monitor power supplies and microprocessor activity. The family offers various combinations of reset outputs, watchdog timers, and manual resets, available in multiple factory-trimmed threshold voltages ranging from 2.5V to 5V.

Supervisors Replacement Considerations

Direct substitutes within the same family include MAX6316HUK46CY+T and MAX6318HUK46CY+T, which share similar packages and thresholds but differ in specific features like watchdog presence or output type. Verify functional equivalence carefully.
