MAX6388XS31D5-T

Supervisors Overview

The MAX6388XS31D5-T is a dual-channel voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.8V to 5V and features an active-high, push-pull reset output. The device monitors two independent input channels with a fixed reset threshold voltage of 3.15V and an adjustable overvoltage threshold of 3.15V. It provides a minimum reset timeout delay of 2.4 seconds and consumes only 7µA of supply current. The component is housed in a compact SC-70-4 surface-mount package and supports operation across an industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Dual-channel voltage monitoring capability for independent power supply supervision
• Active-high push-pull reset output configuration without manual reset or watchdog functions
• Ultra-low power consumption suitable for battery-operated applications
• Compact SC-70-4 surface-mount packaging for space-constrained designs

Supervisors Applications

• Portable electronic devices requiring low-power voltage supervision
• Battery-powered systems needing dual-rail monitoring
• Industrial control units operating in extended temperature environments
• Embedded microprocessor reset circuits

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance and lead-free specifications against specific manufacturing lot data. Check for obsolescence notices from Analog Devices. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly. Validate pinout compatibility with target PCB footprint during integration planning.

Supervisors Selection Notes

Select this component when dual-channel supervision with active-high outputs is required. Verify that the 3.15V threshold aligns with system voltage rails. Consider the 2.4-second timeout duration against system startup requirements. Evaluate the SC-70-4 package size against available board space. Confirm operational temperature range meets environmental specifications.
