MAX6738XKVD3

Supervisors Overview

The MAX6738XKVD3+T is a low-power microprocessor supervisor IC from Analog Devices Inc./Maxim Integrated, housed in a compact SC-70-5 surface-mount package. It monitors two voltage rails with threshold values of 1.62 V and 0.81 V. The device features an active-low open-drain reset output and manual reset capability. It operates within a supply voltage range up to 5.5 V and maintains accuracy within 3%. The reset delay time is specified at 225 ms, and the component supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Dual-voltage monitoring with independent threshold detection for critical power rails
• Manual reset input allows for system-initiated restarts
• Low quiescent current consumption suitable for battery-powered applications
• Compact SC-70-5 footprint designed for space-constrained PCB layouts

Supervisors Applications

• Portable electronic devices requiring multi-rail power supervision
• Battery-operated systems needing low standby current
• Embedded controllers with manual reset requirements
• Industrial control modules operating in extended temperature ranges

Supervisors Procurement Notes

Verify the complete part number including suffixes such as +T for tape-and-reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure compatibility with existing board footprints by reviewing the SC-70-5 mechanical dimensions. Cross-reference datasheet revisions to confirm pinout consistency with previous design iterations.

Supervisors Selection Notes

Select this component when dual-supply monitoring is required without watchdog functionality. Compare against single-channel supervisors if only one rail needs oversight. Evaluate the 225 ms reset delay against system startup timing requirements. Consider the SC-70-5 package size relative to available board real estate compared to larger SOT packages.

Supervisors Part Context

This device belongs to the MAX6736/MAX6738 family of low-power voltage supervisors. These components are designed to provide reliable reset signals for microprocessors and memory devices. The series emphasizes low current draw and high accuracy, making them suitable for portable electronics where power efficiency is critical.

Supervisors Replacement Considerations

The MAX6736XKVDD3+T serves as a functional substitute within the same family, offering similar dual-voltage monitoring capabilities in the SC-70-5 package. Verify that threshold voltages and reset delays align with specific design requirements before substitution.
