MAX6385XS35D1-T

Supervisors Overview

The MAX6385XS35D1-T is a single-channel microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors power-supply voltages within the +1.8V to +5.0V range and features a factory-set reset threshold voltage of 3.5V. The device provides an active-high, push-pull output with a manual reset input capability. It operates with a supply current of 7µA and includes a reset timeout period of 20ms. The component is housed in a compact SC-70-4 surface-mount 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 high accuracy
• Provides active-high push-pull output for reliable logic interfacing
• Includes manual reset input for system control flexibility
• Operates with low supply current consumption suitable for battery-powered designs

Supervisors Applications

• Microprocessor reset circuits in embedded systems
• Power management supervision in portable electronics
• Industrial control systems requiring wide temperature operation
• Communication equipment power monitoring

Supervisors Procurement Notes

Verify availability status as this part may be subject to limited supply or special order requirements. Confirm RoHS compliance and lead-free status through official datasheets. Ensure the SC-70-4 package matches your PCB footprint design. Check for obsolescence notices from Analog Devices before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 3.5V threshold is required for voltage supervision. The active-high output suits applications needing positive logic reset signals. Consider the 7µA quiescent current for low-power constraints. Verify that the 20ms timeout meets your processor startup timing requirements.

Supervisors Part Context

This part belongs to the MAX6381–MAX6390 family of single/dual low-voltage, low-power µP reset circuits. These devices offer factory-set thresholds in approximately 100mV increments with ±2.5% accuracy over temperature. The series provides multiple timeout periods and output options to accommodate diverse microprocessor reset needs.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the MAX6385 series with different threshold voltages if 3.5V is unsuitable. Verify equivalent packages like SC-70-4 or uDFN4 for mechanical compatibility. Cross-reference with MAX6381–MAX6390 variants offering similar electrical characteristics.
