ADM6384YKS45D3Z-R7

Supervisors Overview

The ADM6384YKS45D3Z-R7 is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range up to 5.5 V and features a fixed reset threshold of 4.5 V. The device provides a push-pull active-low reset output with a manual reset input capability. It includes a fixed reset delay time of 280 ms and draws a typical operating supply current of 13 µA. The component is designed for operation across an extended temperature range from -40°C to +125°C and is housed in a compact 4-lead SC-70 package.

Supervisors Feature Summary

• Precision power supply monitoring with guaranteed reset output validity down to 1 V
• Manual reset input allows external control over the reset state
• Push-pull active-low reset output stage ensures strong drive capability
• Power supply glitch immunity protects against transient disturbances

Supervisors Applications

• Microprocessor systems requiring reliable power supervision
• Portable equipment needing low standby current consumption
• Controllers and intelligent instruments operating in harsh environments

Supervisors Procurement Notes

Verify the specific suffix D3Z corresponds to the 4.5 V threshold and 280 ms timeout configuration, as the ADM6384 series utilizes alphanumeric codes to define electrical parameters. Confirm RoHS compliance status through official documentation. Check lifecycle status as some variants may be approaching end-of-life. Ensure the SC-70-4 package availability matches your PCB footprint requirements before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed 4.5 V monitoring level is required for single-channel voltage supervision. The 280 ms timeout suits applications where moderate startup delays are acceptable. Consider the 13 µA quiescent current for battery-powered designs. Verify that the active-low output polarity aligns with the target processor's reset pin logic. The wide temperature range supports industrial and automotive-grade deployment scenarios.

Supervisors Part Context

This part belongs to the ADM6384 family of microprocessor reset generators. The series offers multiple threshold voltage options ranging from 1.58 V to 5.0 V and various timeout periods. The YKS29D3Z variant monitors 2.93 V, while the YKS45D3Z variant specifically targets 4.5 V rails. All variants share the same SC-70-4 package and functional architecture, differing primarily in internal reference voltages and timing configurations.

Supervisors Replacement Considerations

Direct substitutes include other ADM6384 variants with matching 4.5 V thresholds and 280 ms timeouts, such as ADM6384YKS45D3Z-RL7. Cross-reference with MAX6385 series devices for similar functionality, ensuring pin compatibility and electrical parameter alignment. Verify that alternative components support the same manual reset feature and push-pull output structure.
