ADM1815-5ARTZ-RL7

Supervisors Overview

The ADM1815-5ARTZ-RL7 is a voltage 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 3.06 V. The device provides a push-pull output type with a standard reset delay time of 250 ms. It is designed for single-input monitoring without manual reset, watchdog timer, or battery backup switch capabilities. The component supports surface mount installation in an RT-3 (SOT-23) package and functions across an operating temperature range from -40°C to +105°C.

Supervisors Feature Summary

• Provides reliable low-cost voltage monitoring with a dedicated reset output for system supervision
• Features a fixed 3.06 V reset threshold level suitable for standard power supply voltages
• Delivers a push-pull output signal with a consistent 250 ms reset delay time

Supervisors Applications

• Monitoring 2.5 V, 3 V, 3.3 V, and 5 V power supply rails
• Ensuring correct system startup sequences through power-on reset generation
• Maintaining system integrity during voltage fluctuations via supervisory circuitry

Supervisors Procurement Notes

Verify the exact suffix RL7 against official Analog Devices documentation to confirm reel packaging specifications. Confirm RoHS compliance status directly with the manufacturer as regulatory details may vary by production batch. Ensure the SOT-23 footprint matches your PCB design constraints before procurement. Cross-reference the 3.06 V threshold requirement with your specific power rail tolerance needs.

Supervisors Selection Notes

Select this component when a fixed 3.06 V threshold is required for supervising standard logic supply voltages. The push-pull output eliminates the need for external pull-up resistors compared to open-drain alternatives. Consider the 250 ms delay duration to ensure it aligns with your microprocessor initialization timing requirements. Verify that the SOT-23 package size fits within your available board space constraints.

Supervisors Part Context

This part belongs to the ADM1815 series of microprocessor reset circuits from Analog Devices. The series offers various threshold options to accommodate different power supply standards. The ADM1815-5ARTZ-RL7 specifically targets applications requiring precise supervision of common digital logic voltage levels. It serves as a fundamental building block for ensuring stable operation in embedded systems.

Supervisors Replacement Considerations

Check for ADM1815 variants with different thresholds if 3.06 V does not match your rail. Compare ADM1817 models which share similar form factors but may differ in output configuration. Verify pinout compatibility with existing designs before substituting any alternative supervisory ICs.
