MAX6318LHUK46CY+T

Supervisors Overview

The MAX6318LHUK46CY+T is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 4.6 V, with specific overvoltage and undervoltage thresholds at 4.699 V and 4.561 V respectively. The device monitors one input and provides active high, active low, and push-pull outputs. It includes a watchdog timer and has a reset delay time of 200 ms. Operating temperatures range from -40 °C to +125 °C, with a typical operating supply current of 10 µA.

Supervisors Feature Summary

• Integrates a watchdog timer for system fault detection
• Provides multiple output configurations including active high, active low, and push-pull
• Features low power consumption suitable for battery-operated applications

Supervisors Applications

• Portable equipment requiring voltage supervision
• Battery-powered systems needing power management
• Industrial control systems monitoring single voltage rails

Supervisors Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct threshold voltage and package configuration. Confirm RoHS compliance status and lead times through authorized distributors. Check for obsolescence notices or lifecycle changes before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 4.6 V threshold is required for single-input voltage monitoring. Consider the integrated watchdog functionality if software lockup protection is needed. Ensure the SOT-23-5 package fits the design constraints and that the operating temperature range meets environmental requirements.

Supervisors Part Context

This part belongs to the MAX6318 series of uPower Supervisors designed for low-power applications. It is part of Maxim Integrated's portfolio of power management solutions, now under Analog Devices. The series offers various threshold voltages and package options to suit different system monitoring needs.

Supervisors Replacement Considerations

Check for direct pin-to-pin replacements within the MAX6318 family with different threshold voltages. Verify compatibility with existing PCB layout and electrical specifications before substituting.
