MAX6389XS32D1+T

Supervisors Overview

The MAX6389XS32D1+T is a dual-channel voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors two independent input voltages within a range of 1.8 V to 5 V, featuring an adjustable overvoltage threshold set at 3.28 V. The device provides active low, open-drain reset outputs with a minimum reset delay time of 2 ms. It operates on a supply current of 7 µA and supports surface mount installation in an SC-70-4 package. The component functions across a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Dual-channel voltage monitoring capability for independent power rails
• Adjustable overvoltage detection threshold for flexible system protection
• Ultra-low quiescent current consumption suitable for battery-powered applications
• Compact SC-70-4 surface-mount packaging for space-constrained designs

Supervisors Applications

• Portable electronic devices requiring multi-rail power supervision
• Industrial control systems needing robust voltage monitoring
• Consumer electronics with limited board space and low power constraints

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure storage conditions adhere to moisture sensitivity level guidelines to maintain reliability. Cross-reference ordering information with official datasheets to confirm exact suffix specifications.

Supervisors Selection Notes

Select this component when dual-voltage supervision is required in a minimal footprint. The adjustable overvoltage threshold allows customization for specific rail protection needs. Consider the 7 µA operating current for energy-sensitive designs. Verify that the SC-70-4 package aligns with PCB layout constraints and thermal management requirements.

Supervisors Part Context
