MAX6385XS26D2-T

Supervisors Overview

The MAX6385XS26D2-T is a single-channel microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of +1.8V to +5.0V and features a factory-set reset threshold of 2.6V. The device provides an active-high, push-pull reset output with a manual reset input capability. It offers a minimum reset timeout period of 40ms and consumes low supply current. The component is available in SC-70-4 surface-mount packaging and supports operation across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Monitors power-supply voltages from +1.8V to +5.0V with high accuracy
• Features an active-high, push-pull reset output for direct logic interfacing
• Includes a manual reset input for system control flexibility
• Operates at low supply current levels suitable for battery-powered applications

Supervisors Applications

• Microprocessor reset circuits in embedded systems
• Power management supervision in portable electronics
• Industrial control system voltage monitoring
• Consumer device power integrity verification

Supervisors Procurement Notes

Verify the specific suffix D2 against official datasheets to confirm the 40ms timeout variant. Confirm RoHS compliance status (+T suffix) and lead-free specifications prior to ordering. Check availability constraints as limited stock or special order conditions may apply. Ensure the SC-70-4 package matches PCB footprint requirements. Validate operating temperature range suitability for the target environment.

Supervisors Selection Notes

Select this component when an active-high reset signal is required rather than the common active-low configuration. The manual reset input allows for external system-initiated resets. Verify that the 2.6V threshold aligns with the monitored rail voltage. Consider the 40ms timeout duration relative to the target processor's startup time. Ensure the SC-70-4 package fits the design constraints.

Supervisors Part Context

This part belongs to the MAX6381–MAX6390 series of low-voltage, low-power microprocessor reset circuits. The series offers various threshold voltages, timeout periods, and output configurations. The MAX6385 specifically denotes the active-high output variant with manual reset capability. Other series members include active-low push-pull and open-drain options.

Supervisors Replacement Considerations

Cross-reference with other MAX6385 variants differing only in threshold voltage or timeout delay if electrical parameters require adjustment. Verify pinout compatibility before substituting with similar single-channel supervisors from the same family.
