MAX6348XR41

Overview

The MAX6348XR41 is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range up to 5.5 V and features an overvoltage threshold of 3.958 V. The device provides a reset delay time of 280 ms and draws a working power current of 500 nA. It supports a minimum operating temperature of -40 C and a maximum of +85 C. The component utilizes an SC-70-3 package with SMD/SMT installation style. It monitors one input and outputs an active low, open drain signal. The part does not include manual reset, watchdog timer, battery backup switch, or chip enable functions.

Feature Summary

• Ultra-low-power operation with minimal current consumption for extended battery life
• Compact SC-70-3 surface-mount package design for space-constrained applications
• Active low open-drain output configuration for flexible logic interfacing

Applications

• Monitoring main supply rails in portable electronic devices
• Voltage supervision in microprocessor systems requiring reset signals
• Power management circuits in industrial control equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot codes against official documentation. Check availability constraints as limited supply situations may occur. Ensure storage conditions meet specified temperature ranges to maintain performance integrity prior to assembly.

Selection Notes

Select this component when ultra-low quiescent current is critical for system efficiency. The fixed overvoltage threshold suits applications monitoring standard 3.3 V or 5 V rails. Consider the absence of manual reset and watchdog features during system design. Evaluate the SC-70-3 footprint compatibility with existing PCB layouts before integration.

Part Context
