MAX6381XR46D2/V+T

Supervisors Overview

The MAX6381XR46D2/V+T is a single-channel microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors power supply voltages ranging from +1.8V to +5.0V with a factory-set reset threshold of 4.63V. The device features an active-low, open-drain reset output and provides a minimum reset timeout period of 40ms. It operates within a temperature range of -40°C to +125°C and consumes only 7µA of supply current at +1.8V. The maximum operating voltage is 5.5V, and it is housed in an SC-70-3 package.

Supervisors Feature Summary

• Monitors power-supply voltages from +1.8V to +5.0V while consuming low supply current
• Provides active-low, open-drain reset output guaranteed valid down to VCC = 1V
• Factory-set reset threshold voltage with ±2.5% accuracy over the full temperature range

Supervisors Applications

• Microprocessor (µP) supervisory circuits
• Power supply monitoring systems
• Battery-powered electronic devices

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free specifications as indicated in official documentation. Check for any product change notices or obsolescence alerts prior to procurement. Ensure packaging details match project requirements for surface-mount installation.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with an open-drain output is required. Consider the 4.63V threshold for applications where the supply rail must be monitored precisely above standard logic levels. The wide operating temperature range supports industrial and automotive environments. Verify that the open-drain configuration aligns with the system's pull-up resistor design.

Supervisors Part Context

This part belongs to the MAX6381–MAX6390 series of SC70/µDFN, single/dual low-voltage, low-power µP reset circuits. The series offers various reset thresholds, timeout periods, and output options to accommodate different system requirements. The MAX6381 variant specifically provides a push-pull active-low output, but the D2 suffix indicates an open-drain configuration in this specific part number.
