MAX6316LUK46CY-T

Supervisors Overview

The MAX6316LUK46CY-T is a microprocessor supervisory circuit designed to monitor power supplies in digital systems. It features a fixed reset threshold voltage of 4.6V and an active-low push-pull reset output. The device includes a manual reset input and a watchdog timer with a typical timeout period of 200ms. It operates within a supply voltage range up to 5.5V, consumes 10µA of quiescent current, and functions across an industrial temperature range from -40°C to +125°C. The component is housed in a compact SOT-23-5 surface-mount package.

Supervisors Feature Summary

• Monitors power supply voltage levels against a factory-trimmed threshold
• Integrates a watchdog timer for processor activity supervision
• Includes a manual reset input for system control
• Provides an active-low push-pull reset output

Supervisors Applications

• Microprocessor power supply monitoring
• Digital system reset generation
• Watchdog timer implementation in embedded controllers

Supervisors Procurement Notes

Verify the exact suffix configuration as datasheets may list CY+T or CY-T variants. Confirm RoHS compliance status for the specific lot. Check production lifecycle status as availability may be limited. Ensure the operating temperature range meets application requirements. Validate pinout compatibility during PCB layout.

Supervisors Selection Notes

Select this part when a fixed 4.6V threshold is required. Choose the push-pull output stage if driving capacitive loads. Verify that the 200ms watchdog timeout suits the processor clock speed. Consider the SOT-23-5 package size constraints. Ensure the 10µA current consumption fits the power budget.

Supervisors Part Context

This component belongs to the MAX6316–MAX6322 family of 5-pin µP supervisory circuits. These devices are designed to ignore fast negative transients on VCC. Resets are guaranteed valid down to 1V. The family offers various threshold voltages and output stages. They are widely used in portable and industrial electronics requiring reliable power management.

Supervisors Replacement Considerations

Check for other MAX6316 series parts with different thresholds or output types. Verify pin-to-pin compatibility with alternative supervisors. Ensure equivalent watchdog functionality if required. Confirm package and thermal characteristics match.
