MAX6385XS34D3-T

Supervisors Overview

The MAX6385XS34D3-T is a single-channel microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors power-supply voltages within the +1.8V to +5.0V range while consuming only 3µA of supply current at +1.8V. The device features a factory-set reset threshold voltage of 3.4V and provides an active-high, push-pull reset output. It includes a manual reset input and operates with a minimum reset timeout delay of 280ms. The component supports operation across a temperature range of -40°C to +125°C and is available in SC-70-4 or µDFN packages.

Supervisors Feature Summary

• Monitors power-supply voltages from +1.8V to +5.0V with ultra-low supply current consumption.
• Provides an active-high, push-pull reset output for reliable logic interfacing.
• Includes a manual reset input for system control flexibility.
• Operates reliably across extended industrial temperature ranges.

Supervisors Applications

• Microprocessor (µP) power-supply monitoring
• Portable electronic systems requiring low power
• Battery-powered devices
• Industrial control systems

Supervisors Procurement Notes

Verify the specific suffix D3 against official datasheets to confirm the exact reset threshold voltage and package type, as variations exist within the MAX6385 family. Confirm availability status directly with authorized distributors, as this part number may be subject to limited supply or discontinuation. Ensure compatibility with your system's voltage levels and thermal requirements before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a fixed 3.4V threshold is required for active-high reset signaling. Consider alternative suffixes if different thresholds or active-low outputs are needed. Verify that the 280ms timeout meets your system's startup timing constraints. Ensure the chosen package fits your PCB layout constraints.

Supervisors Part Context

The MAX6385 series belongs to Maxim Integrated's line of low-voltage, low-power microprocessor reset circuits. These devices are designed to monitor single power supplies and assert a reset signal when voltages fall below specified thresholds. The series offers various threshold options and output configurations to suit diverse application needs.

Supervisors Replacement Considerations

Check for other MAX6385 variants with matching 3.4V thresholds and active-high outputs. Verify pinout compatibility if substituting with similar supervisory ICs from other manufacturers.
