MAX6385XS45D5-T

Supervisors Overview

The MAX6385XS45D5-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 features a factory-set reset threshold voltage of 4.5V. The device provides an active-high, push-pull reset output with a minimum timeout period of 1.12 seconds. Packaged in a compact SC-70-4 surface-mount format, it is designed for low-power applications requiring precise voltage monitoring across industrial temperature ranges from -40°C to +125°C.

Supervisors Feature Summary

• Monitors power-supply voltages with a fixed 4.5V threshold
• Provides active-high push-pull reset output signal
• Ensures stable operation via 1.12-second minimum reset timeout
• Operates reliably across extended industrial temperature ranges

Supervisors Applications

• Microprocessor power supply supervision
• Battery-powered system voltage monitoring
• Industrial control board reset management
• Portable electronic device power integrity

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability upon receipt. Ensure storage conditions adhere to moisture sensitivity level requirements to maintain package integrity before soldering. Cross-reference ordering part numbers with official datasheets to confirm exact threshold and package specifications.

Supervisors Selection Notes

Select this component when an active-high reset signal is required for systems operating at 4.5V thresholds. The SC-70-4 package suits space-constrained designs. Verify that the 1.12-second timeout aligns with system startup timing requirements. Consider alternative MAX6385 variants if active-low outputs or different threshold voltages are needed for the specific application architecture.

Supervisors Part Context

This part belongs to the MAX6381–MAX6390 family of low-voltage, low-power microprocessor reset circuits. The series offers various threshold voltages and timeout periods in small packages. The MAX6385 variant specifically distinguishes itself with an active-high output configuration, contrasting with active-low counterparts like the MAX6381. This family targets portable and battery-operated electronics requiring reliable power management.

Supervisors Replacement Considerations

Direct substitutes include other MAX6385XS45D5-T units or equivalent parts from the same MAX6385 family with identical 4.5V thresholds and active-high outputs. Verify pin compatibility and electrical parameters before substitution.
