MAX6381XR29D3

Supervisors Overview

The MAX6381XR29D3 is a single-channel microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors power-supply voltages ranging from +1.8V to +5.0V with a factory-set reset threshold of 2.93V. The device features an active-low push-pull reset output and a minimum reset timeout delay of 140ms. It operates within a temperature range of -40°C to +125°C and consumes only 3µA of supply current at +1.8V. The component is housed in a lead-free SC-70 package.

Supervisors Feature Summary

• Monitors power-supply voltages from +1.8V to +5.0V
• Provides active-low push-pull reset output
• Ensures system reliability through fixed reset thresholds

Supervisors Applications

• Microprocessor power supply supervision
• Portable battery-operated equipment
• Automotive electronics systems

Supervisors Procurement Notes

Verify the specific manufacturer source, as this component may be sourced from Maxim Integrated or Analog Devices Inc. Confirm RoHS compliance status and check for any lifecycle restrictions, as availability may vary between original manufacturing channels and third-party distributors. Ensure the part number matches the exact suffix requirements for your application.

Supervisors Selection Notes

Select this component when a fixed 2.93V threshold is required for low-voltage monitoring. Consider the SC-70 package size for space-constrained designs. Evaluate the 140ms timeout against system startup requirements. Compare against other MAX6381 variants if different voltage thresholds or output types are needed.

Supervisors Part Context

This part belongs to the MAX6381–MAX6390 series of low-voltage, low-power microprocessor reset circuits. These devices are designed to monitor power supplies and provide reset signals to ensure proper system initialization. The series offers various threshold voltages and timeout delays to accommodate diverse application requirements.

Supervisors Replacement Considerations

Other MAX6381 variants with different threshold voltages or timeout delays may serve as functional replacements if electrical parameters align with design specifications. Verify package compatibility and output type before substitution.
