MAX6385XS37D4-T

Supervisors Overview

The MAX6385XS37D4-T is a single-channel voltage 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 3.7V. The device features an active-high, push-pull output and includes a manual reset input. It operates within a temperature range of -40°C to +125°C and is housed in a compact SC-70-4 surface-mount package.

Supervisors Feature Summary

• Provides precise voltage supervision for microprocessor systems with a fixed 3.7V threshold.
• Features an active-high push-pull reset output for direct logic interface compatibility.
• Includes a manual reset input allowing external control over the reset state.

Supervisors Applications

• Microprocessor (µP) system power monitoring
• Battery-powered portable electronics
• Industrial control board voltage supervision

Supervisors Procurement Notes

Verify the specific suffix D4 against official datasheets to confirm pinout and electrical characteristics, as suffixes define package and threshold variants. Confirm availability status directly with authorized distributors, as supply constraints may apply to this component series. Ensure RoHS compliance documentation matches the specific manufacturing batch requirements for your assembly process.

Supervisors Selection Notes

Select this component when an active-high reset signal is required rather than the more common active-low configuration found in the MAX6384 series. The fixed 3.7V threshold suits applications monitoring standard 3.3V or 5V rails where brown-out detection at this specific level is necessary. The SC-70-4 package offers space savings compared to larger SOIC options while maintaining the same functional capabilities.

Supervisors Part Context

This part belongs to the MAX6381–MAX6390 family of low-voltage, low-power µP reset circuits. The MAX6385 variant specifically denotes the active-high output option, distinguishing it from the MAX6384 which provides an active-low output. All members of this family share similar low current consumption and wide operating temperature ranges.

Supervisors Replacement Considerations

The MAX6385XS37D5-T serves as a lead-free replacement variant within the same series. For active-low requirements, the MAX6384XS37D4-T is the functional equivalent with inverted output polarity. Verify that any substitute maintains the 3.7V threshold and SC-70-4 footprint compatibility.
