MAX6348XR44+T

Overview

The MAX6348XR44+T is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed threshold voltage of 4.4 V for monitoring input lines. The device provides an active low, open-drain output with a reset delay time of 185 ms. It consumes a maximum operating supply current of 1 uA and maintains an accuracy of 2.5%. The component functions reliably across a temperature range of -40 C to +85 C and is housed in a compact SC-70-3L package.

Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Fixed threshold voltage detection for precise power monitoring
• Compact surface-mount packaging for space-constrained designs

Applications

• Portable electronic devices requiring extended battery life
• Embedded systems needing reliable power-on reset signals
• Consumer electronics with limited board space

Procurement Notes

Verify the specific suffix and manufacturer details against official Analog Devices documentation before procurement. Confirm availability status as distribution channels may list restricted or discontinued stock. Ensure the component meets all required environmental and electrical specifications for the intended application environment.

Selection Notes

Select this component when a fixed 4.4 V threshold is required for single-input voltage monitoring. Consider the ultra-low quiescent current for energy-sensitive applications. Verify that the SC-70-3L package fits the design constraints and that the operating temperature range aligns with the system requirements.

Part Context

This part belongs to the MAX6348 series of microprocessor reset circuits designed for low-power applications. It serves as a voltage detector to ensure system stability during power transitions. The series is characterized by minimal current draw and small footprint options, making it suitable for modern portable electronics where power efficiency and size are critical design factors.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family if availability is an issue. Verify that any substitute maintains the same 4.4 V threshold and output configuration.
