MAX6728KASVD3+T

Supervisors Overview

The MAX6728KASVD3+T is a dual-channel ultra-low-voltage supervisor IC manufactured by Analog Devices Inc./Maxim Integrated. It monitors two independent voltage rails with thresholds ranging from 1.8 V to 5 V and 900 mV to 3.3 V. The device features an active low, open-drain reset output and includes a manual reset input. It incorporates a watchdog timer and provides a fixed reset delay time of 210 ms. Operating within a supply voltage range up to 5.5 V, it supports surface-mount installation in an SOT-23-8 package and functions across temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Dual-channel voltage supervision for monitoring multiple power rails simultaneously
• Integrated watchdog timer functionality for system fault detection
• Manual reset capability allowing external trigger control
• Ultra-low-power operation suitable for battery-constrained applications

Supervisors Applications

• Portable electronic devices requiring multi-rail power management
• Embedded systems needing reliable voltage supervision and watchdog protection
• Industrial control units operating in extended temperature environments

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeits. Confirm RoHS compliance status and check for obsolescence notices as this series may have limited availability. Ensure the specific suffix matches required threshold voltages and package variants before ordering.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required alongside watchdog functionality. Verify that the adjustable threshold ranges cover the target supply rails. Consider the SOT-23-8 footprint constraints and ensure the open-drain output interface aligns with the downstream logic requirements.

Supervisors Part Context

This part belongs to the MAX6728 family of ultra-low-voltage supervisors designed for compact, power-sensitive designs. It shares architectural similarities with other Maxim Integrated supervisors but offers specific dual-channel capabilities and manual reset integration tailored for complex embedded architectures.
