MAX6385XS22D2-T

Supervisors Overview

The MAX6385XS22D2-T is a single-channel voltage 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 2.2V. The device provides an active-high, push-pull output and includes a manual reset input. It utilizes an SC-70-4 surface-mount package and offers a minimum reset timeout period of 40ms. The component supports operation across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides active-high push-pull reset output for reliable logic interfacing
• Includes a debounced manual reset input with internal pullup resistor
• Maintains valid reset state down to 1V supply voltage
• Ensures ±2.5% reset threshold accuracy over the full operating temperature range

Supervisors Applications

• Microprocessor power-supply monitoring
• Battery-operated electronic systems
• Portable instrumentation circuits

Supervisors Procurement Notes

Verify the specific suffix D2 against official datasheets to confirm the exact threshold voltage and timeout delay, as these parameters vary significantly across the MAX6385 family. Confirm RoHS compliance status and lead-free specifications directly with the manufacturer or authorized distributors before procurement.

Supervisors Selection Notes

Select this component when an active-high output is required alongside manual reset functionality. Ensure the 2.2V threshold aligns with the monitored rail. Verify that the 40ms timeout meets system startup requirements. Compare against similar parts if open-drain outputs or different thresholds are needed.

Supervisors Part Context

This part belongs to the MAX6381–MAX6390 series of low-voltage microprocessor reset circuits. The series offers various output polarities and timeout periods. The MAX6385 variant specifically distinguishes itself by providing an active-high output and a manual reset pin, differing from the active-low or open-drain options in other series members.

Supervisors Replacement Considerations

Cross-reference with other MAX6385 variants sharing the same SC-70-4 package and active-high output. Verify that substitute parts match the 2.2V threshold and 40ms timeout specifications exactly.
