MAX6385XS16D6-T

Supervisors Overview

The MAX6385XS16D6-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 consumes only 3µA at +1.8V. The device features a factory-set reset threshold voltage of 1.6V with ±2.5% accuracy over temperature. It provides an active-high push-pull output and includes manual reset functionality. The reset timeout period is fixed at 1.12 seconds minimum. It is housed in a compact SC-70-4 package and supports an operating temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Monitors power-supply voltages from +1.8V to +5.0V with ultra-low supply current consumption.
• Provides a factory-set reset threshold voltage with high accuracy across the industrial temperature range.
• Features an active-high push-pull reset output for direct interface compatibility.

Supervisors Applications

• Portable battery-powered equipment requiring low quiescent current
• Microprocessor and DSP power-supply supervision
• Handheld instruments and communication devices

Supervisors Procurement Notes

Verify the specific suffix D6 corresponds to the 1.6V threshold and active-high configuration when sourcing. Confirm RoHS compliance status (+) if required for your assembly process. Check manufacturer lifecycle status as availability may vary. Ensure the SC-70-4 package dimensions match your PCB footprint constraints before finalizing procurement.

Supervisors Selection Notes

Select this component when an active-high output is required, distinguishing it from the standard MAX6385 which typically offers active-low outputs. The 1.6V threshold suits systems monitoring lower voltage rails. Verify that the 1.12s timeout meets system startup requirements. Consider the SC-70-4 package size for space-constrained designs compared to larger packages.

Supervisors Part Context

This part belongs to the MAX6381–MAX6390 series of single/dual low-voltage, low-power µP reset circuits. The 'XS' designation indicates a specific threshold voltage code, while 'D6' specifies the SC-70-4 package. The '-T' suffix denotes tape-and-reel packaging for automated assembly processes.

Supervisors Replacement Considerations

Direct substitutes include other MAX6385 variants with matching active-high outputs and similar thresholds, such as MAX6385XS16D5 or MAX6385XS16D4, provided the package type (SOT-343/SC-70) is compatible. Cross-reference datasheets for exact pinout and electrical parameter alignment.
