MAX6718UKSHD3-T

Supervisors Overview

The MAX6718UKSHD3-T is a dual ultra-low voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors two system power-supply voltages and provides reset signals in an SOT-23 package. The device features active low push-pull outputs, manual reset capability, and operates within a supply voltage range of 1.8 V to 5 V with thresholds from 900 mV to 3.3 V. It includes overvoltage detection at 810 mV and 3 V, a reset delay of 280 ms, and consumes 15 uA of quiescent current. It functions between -40°C and +125°C.

Supervisors Feature Summary

• Dual-channel monitoring for independent system power supplies
• Ultra-low power consumption suitable for battery-operated applications
• Integrated manual reset input for user-controlled initialization
• Overvoltage detection capabilities for enhanced system protection
