MAX6316LUK45CY+T

Supervisors Overview

The MAX6316LUK45CY+T is a microprocessor supervisory circuit in a 5-pin SOT-23 package. It monitors a single voltage input with a fixed threshold of 4.5V and an overvoltage limit of 4.599V. The device features an active-low push-pull reset output with a 200ms timeout period. Operating from -40°C to +125°C, it draws 10µA supply current and supports up to 5.5V supply voltage.

Supervisors Feature Summary

• Integrates watchdog timer functionality for system activity monitoring
• Includes manual reset input capability for user-initiated control
• Provides factory-trimmed reset threshold voltages for precision supervision

Supervisors Applications

• Digital system power supply monitoring
• Microprocessor activity supervision
• Embedded controller reset generation

Supervisors Procurement Notes

Verify the exact suffix CY against official Analog Devices documentation to confirm temperature range and package variant. Confirm RoHS compliance status via the manufacturer datasheet. Check production lifecycle status as availability may be limited or subject to specific order increments.

Supervisors Selection Notes

Select this component when a fixed 4.5V threshold is required for single-supervision applications. Ensure the design accommodates the 5-pin SOT-23 footprint. Verify that the active-low push-pull output stage matches the target processor's reset input requirements.

Supervisors Part Context

Part of the MAX6316–MAX6322 family of 5-pin µP supervisory circuits. This series offers various combinations of reset outputs, watchdog timers, and manual reset features. The devices are designed to ignore fast negative transients on VCC and guarantee valid resets down to 1V.

Supervisors Replacement Considerations

Cross-reference with other MAX6316 variants sharing the same 4.5V threshold but different suffixes for package or temperature differences. Verify pinout compatibility before substitution.
