MAX6316LUK45CY+

Supervisors Overview

The MAX6316LUK45CY+T is a microprocessor supervisory circuit in a 5-pin SOT-23 package. It features a fixed reset threshold voltage of 4.5V and an active-low push-pull output. The device includes a watchdog timer with a typical timeout of 1.6 seconds and a manual reset input. It operates within a supply voltage range up to 5.5V, with a quiescent current of 10µA. The reset delay time is 200ms, and the operating temperature range spans from -40°C to +125°C.

Supervisors Feature Summary

• Integrates a watchdog timer for monitoring microprocessor activity
• Includes a manual reset input for system control
• Provides active-low push-pull reset output
• Designed to ignore fast negative transients on VCC

Supervisors Applications

• Digital systems requiring power supply supervision
• Microprocessor activity monitoring
• Embedded systems with watchdog requirements

Supervisors Procurement Notes

Verify the specific suffix 'CY' against the manufacturer's official documentation to confirm the exact reset threshold voltage and package variant. Ensure the component matches the required electrical specifications for your design. Cross-reference the ordering part number with Analog Devices or Maxim Integrated datasheets to avoid discrepancies in factory-trimmed parameters.

Supervisors Selection Notes

Select this component when a fixed 4.5V reset threshold is required alongside integrated watchdog functionality. Consider the 10µA quiescent current for low-power applications. Verify that the active-low push-pull output stage suits the target microprocessor interface. Confirm the 200ms reset delay meets the system startup timing requirements.

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, watchdog timers, and manual resets. These devices are designed to monitor power supplies and microprocessor activity in digital systems, featuring factory-trimmed reset thresholds.

Supervisors Replacement Considerations

Other parts in the MAX6316–MAX6322 family may serve as substitutes if they match the required reset threshold, output type, and package. Verify compatibility with the specific application requirements before replacement.
