MAX6388XS39D1-T

Supervisors Overview

The MAX6388XS39D1-T is a dual-channel microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.8 V to 5 V and features an adjustable overvoltage threshold set at 3.9 V. The device provides active high, push-pull reset outputs for two monitored inputs without manual reset or watchdog timer functionality. It consumes 7 µA of supply current and offers a reset delay time of 2.4 seconds. The component is housed in an SC-70-4 package and supports surface mount installation across an operating temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Dual-channel monitoring with adjustable overvoltage detection capabilities
• Active high push-pull output configuration for direct logic interfacing
• Ultra-low power consumption suitable for battery-operated applications

Supervisors Applications

• Microprocessor system power supervision
• Portable electronic device voltage monitoring
• Industrial control board power integrity verification

Supervisors Procurement Notes

Verify the specific suffix D1 against official datasheets to confirm the exact threshold voltage and package variant, as suffixes define electrical parameters. Confirm RoHS compliance status for the specific revision. Check lead-free markings if required by assembly standards. Validate availability through authorized distributors due to potential lifecycle restrictions.

Supervisors Selection Notes

Select this component when dual independent voltage rails require simultaneous supervision with adjustable overvoltage protection. The SC-70-4 package suits space-constrained designs. Ensure the 2.4-second timeout meets system startup requirements. Verify that active high outputs align with the target controller's reset input polarity.

Supervisors Part Context

This part belongs to the MAX6388 series of low-voltage, low-power reset circuits. The series includes single and dual channel variants with various fixed and adjustable thresholds. The MAX6388 specifically targets applications requiring compact footprints and minimal quiescent current while providing reliable power management supervision for digital systems.

Supervisors Replacement Considerations

Cross-reference with other MAX6388XS variants sharing the SC-70-4 package. Verify pin compatibility and electrical parameter alignment before substitution. Consult manufacturer documentation for updated lifecycle status and recommended alternative part numbers.
