MAX6353RVUK

Overview

The MAX6353RVUK+T is a dual-input voltage supervisor from the MAX6353L series by Analog Devices Inc./Maxim Integrated. It monitors two independent power rails with factory-set thresholds of 1.67V and 2.78V, providing active-low push-pull reset outputs referenced to VCC1. The device features a manual reset input, a fixed 180ms reset delay, and operates within an extended temperature range of -40°C to +85°C. With a supply current of 20µA and accuracy of 1.5%, it ensures reliable system supervision in compact SOT-23-5 packages.

Feature Summary

• Dual-channel monitoring for independent power supply supervision
• Active-low push-pull reset output referenced to VCC1
• Debounced manual reset input for TTL/CMOS compatibility
• Low quiescent current suitable for portable applications

Applications

• Portable electronic devices requiring multi-voltage supervision
• Battery-powered systems with multiple power rails
• Embedded microprocessor systems needing reliable reset generation
• Industrial control units operating in extended temperature ranges

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lot traceability upon receipt. Check datasheet specifications against application requirements to ensure threshold voltages match system needs. Validate package integrity and pin configuration before soldering. Maintain proper ESD handling procedures during storage and assembly.

Selection Notes

Select this component when dual-voltage monitoring with fixed thresholds is required. Compare threshold values against target supply rails to ensure proper reset activation. Consider the 180ms reset delay duration relative to system startup timing requirements. Evaluate the 20µA supply current impact on overall power budget. Verify SOT-23-5 package compatibility with PCB layout constraints.

Part Context

Part of the MAX6353L family offering precision monitoring for multiple power supplies. Designed to improve system reliability compared to discrete components. Provides factory-set thresholds eliminating external resistor networks. Compatible with standard CMOS logic levels for easy integration into existing designs.

Replacement Considerations

MAX6353UWUK+T offers similar functionality with different threshold voltages (1.67V, 2.78V). MAX6354LTUK+T provides alternative thresholds (3.08V, 4.63V) for higher voltage applications. Verify threshold compatibility and package pinout alignment before substitution.
