MAX6383XR16D6+T

Supervisors Overview

The MAX6383XR16D6+T is a single-channel microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors power-supply voltages within the 1.8 V to 5 V range, featuring a factory-set reset threshold of 1.58 V. The device provides an active-low, open-drain reset output with a fixed timeout delay of 560 ms. It operates on a supply voltage up to 5.5 V and consumes only 7 µA of supply current. The component is housed in a compact SC-70-3 surface-mount package and supports an operating temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides reliable system reset via active-low open-drain output when monitored voltage drops below threshold
• Ultra-low power consumption ensures minimal impact on battery-operated applications
• Compact SC-70-3 packaging facilitates space-constrained board designs

Supervisors Applications

• Portable electronic devices requiring low-power supervision
• Battery-powered systems needing voltage monitoring
• Embedded microprocessor reset circuits

Supervisors Procurement Notes

Verify the specific suffix 'XR16D6+T' against official datasheets to confirm the exact threshold voltage and package type. Ensure compatibility with existing PCB footprints for the SC-70-3 package. Check for RoHS compliance status if required by project specifications. Confirm availability through authorized distributors as lead times may vary.

Supervisors Selection Notes

Select this component when a fixed 1.58 V threshold and 560 ms timeout are required. It is suitable for applications prioritizing low quiescent current over adjustable thresholds. Consider alternative packages like UDFN-6 if higher pin counts or different thermal properties are needed. Verify that the open-drain output configuration matches the downstream logic requirements.

Supervisors Part Context

This part belongs to the MAX6381–MAX6390 family of low-voltage, low-power microprocessor reset circuits. These devices are designed to monitor power supplies and assert reset signals during brown-out conditions. The family offers various threshold voltages and timeout delays to suit different system requirements.

Supervisors Replacement Considerations

Direct substitutes include other MAX6383 variants with matching SC-70-3 packages and similar electrical characteristics. Verify threshold voltage and timeout delay compatibility before substitution.
