MAX6418UK16

Supervisors Overview

The MAX6418UK16+T is a dual-voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It features two independent voltage monitoring channels with adjustable reset thresholds, allowing for precise supervision of multiple power rails within a system. The device operates on a supply voltage range of 1.0V to 5.5V and draws a typical quiescent current of 2.7µA, making it suitable for battery-powered applications. It provides an active-low, push-pull reset output with a capacitor-adjustable timeout delay to ensure reliable system recovery during power transients or brownouts.

Supervisors Feature Summary

• Dual-channel voltage monitoring capability for supervising two independent power supplies simultaneously
• Adjustable reset threshold inputs allow customization of trip points for specific application requirements
• Capacitor-adjustable reset timeout period provides flexibility in managing reset delays based on external component selection
• Active-low, push-pull reset output ensures robust drive capability and compatibility with various logic families

Supervisors Applications

• Portable consumer electronics requiring multi-rail power management
• Battery-operated devices needing low-power voltage supervision
• Industrial control systems with complex power distribution networks
• Embedded computing platforms requiring reliable reset sequencing

Supervisors Procurement Notes

Verify the exact suffix (e.g., +T) against the manufacturer's official ordering guide to confirm packaging and tape/reel specifications. Ensure the selected part number matches the required threshold voltage codes defined in the datasheet. Confirm RoHS compliance status through the manufacturer's documentation before procurement. Check for any recent product change notices that may affect pinout or electrical characteristics.

Supervisors Selection Notes

Select this component when dual-voltage supervision with customizable thresholds is required. Evaluate the external capacitor value needed to achieve the desired reset timeout duration. Consider the operating temperature range and supply voltage limits to ensure compatibility with the target system environment. Verify that the push-pull output interface aligns with the downstream logic requirements.
