ADM1815-20ARTZ-RL7

Supervisors Overview

The ADM1815-20ARTZ-RL7 is a supervisory circuit manufactured by Analog Devices Inc., designed as a reset generator IC. It operates within a supply voltage range of 2.7V to 5.5V and features a fixed threshold voltage of 2.0V for monitoring power rails. The device provides a push-pull output and includes a typical reset delay time of 250 ms to ensure stable system initialization. It is housed in a compact SOT-23-3 surface-mount package, suitable for space-constrained applications. The component supports an operating temperature range from -40°C to +85°C and consumes a low quiescent current of 16 µA.

Supervisors Feature Summary

• Fixed 2.0V threshold voltage for precise power rail supervision
• Push-pull output configuration for direct interface with digital logic
• Low power consumption with 16 µA quiescent current
• Compact SOT-23-3 surface-mount packaging

Supervisors Applications

• Portable battery-powered equipment requiring reliable power management
• Microcontroller and microprocessor systems needing clean reset signals

• Industrial control systems operating in extended temperature ranges

Supervisors Procurement Notes

Verify the specific suffix 'RL7' indicates reel packaging when sourcing. Confirm the manufacturer part number matches exactly to avoid confusion with similar ADM181x variants that may have different threshold voltages or output types. Check RoHS compliance status through official documentation before integration into regulated products.

Supervisors Selection Notes

Select this component when a fixed 2.0V reset threshold is required for 3.3V or 5V systems. Consider the SOT-23-3 package size against available PCB real estate. Evaluate the 250 ms reset delay against system startup timing requirements. Ensure the operating temperature range meets environmental specifications.

Supervisors Part Context

This part belongs to the ADM181x series of supervisory circuits from Analog Devices. These devices are engineered for simple, cost-effective power monitoring solutions. The series offers various threshold options and packages to suit diverse application needs while maintaining high reliability and low power consumption characteristics typical of Analog Devices' analog signal chain products.

Supervisors Replacement Considerations

Direct substitutes include other ADM1815 variants with identical 2.0V thresholds but different packaging or tape/reel configurations. Cross-reference with ADM1815-2ARTZ-RL7 for pin-compatible alternatives if package variations exist. Verify functional equivalence regarding reset delay and output type before substitution.
