MAX6348XR46-T

Overview

The MAX6348XR46-T is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 4.63 V for monitoring a single input. The device provides an active low, open drain output with a reset delay time of 280 ms. It consumes a typical operating supply current of 500 nA and maintains an accuracy of 1.5%. The component is designed for surface mount installation in SC-70-3 packages and functions reliably across a temperature range from -40°C to +85°C.

Feature Summary

• Ultra-low-power consumption suitable for battery-operated applications
• Fixed factory-set reset threshold for simplified design
• Compact three-pin surface-mount packaging

Applications

• Portable electronic devices requiring power supervision
• Battery-powered systems needing voltage monitoring
• Embedded microprocessor reset circuits

Procurement Notes

Verify the exact suffix designation against official manufacturer documentation, as variations such as +T or D2 may indicate specific tape-and-reel configurations or lead-free status. Confirm availability through authorized distributors, as stock levels fluctuate. Ensure the selected variant matches the required package type and thermal specifications for your specific application environment before finalizing procurement.

Selection Notes

Select this component when a fixed 4.63 V threshold is required for single-supervision tasks. Consider the 500 nA quiescent current for energy-sensitive designs. Verify that the SC-70-3 package fits your board layout constraints. Ensure the 280 ms timeout meets system startup requirements. Compare against other MAX6348 variants if different thresholds or packages are needed.
