MAX6348XR34-T

Overview

The MAX6348XR34-T 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 active low, open-drain output. The device monitors a single input with a specific overvoltage threshold of 3.451 V. It provides a fixed reset delay time of 280 ms and consumes a typical operating supply current of 500 nA. The component is housed in a SC-70-3 surface-mount package and is rated for operation between -40°C and +85°C.

Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Compact SC-70-3 surface-mount packaging for space-constrained designs
• Fixed reset delay ensures stable system initialization

Applications

• Portable electronic devices requiring low standby current
• Battery-powered instrumentation systems
• Embedded controllers needing voltage supervision

Procurement Notes

Verify the exact suffix and manufacturer documentation when sourcing this component. Confirm RoHS compliance status and lead-free specifications against the latest datasheet. Check for obsolescence notices or lifecycle changes from Analog Devices. Ensure the SC-70-3 package matches your PCB footprint requirements before procurement.

Selection Notes

Select this part for applications requiring minimal quiescent current and a compact form factor. The fixed 3.451 V threshold suits specific rail monitoring needs. Consider the 280 ms delay for system timing constraints. Verify compatibility with the target voltage rails and temperature range requirements.

Part Context

This component belongs to the MAX6348 series of uPower Reset Circuits. It is designed for monitoring power supplies in portable and industrial applications. The series offers various threshold voltages and package options to accommodate different design constraints while maintaining low power characteristics.

Replacement Considerations

Check for direct pin-compatible substitutes within the MAX6348 family with adjusted thresholds. Verify equivalent packages like SOT-23-3 if SC-70-3 is unavailable. Ensure replacement parts match the 500 nA current and 280 ms delay specifications.
