ADM1816-R22ARTZ-RL

Supervisors Overview

The ADM1816-R22ARTZ-RL is a supervisory circuit reset generator IC manufactured by Analog Devices Inc. It operates within a maximum supply voltage of 5.5 V and features a fixed threshold voltage of 2.18 V. The device provides a reset delay time of 250 ms and utilizes an open drain or push-pull output type. It is designed for single-input monitoring without manual reset, watchdog timer, or battery backup switch capabilities. The component is housed in a compact SOT-23-3 package suitable for surface mount applications.

Supervisors Feature Summary

• Provides simple reset and power-on reset functionality for microprocessor systems
• Offers low-cost, space-saving design in a small SOT-23 package
• Features a fixed threshold voltage for precise power supply monitoring

Supervisors Applications

• Microprocessor reset circuits
• Power supply supervision
• Embedded system power management

Supervisors Procurement Notes

Verify the exact suffix 'R7' versus 'RL' as distributors may list them interchangeably but with different packaging. Confirm the 2.18V threshold variant matches the specific 'R22' designation. Check current availability status as some listings indicate limited supply or discontinuation risks. Ensure the SOT-23-3 package aligns with PCB footprint requirements.

Supervisors Selection Notes

Select this part when a fixed 2.18V threshold is required for single-channel voltage monitoring. Consider the 250ms reset delay for system stability needs. Verify compatibility with the target logic levels given the open drain or push-pull output options. Ensure the operating temperature range meets the application's environmental specifications.

Supervisors Part Context

This component belongs to the ADM181x series of microprocessor reset circuits from Analog Devices. The series is known for providing reliable power-supply supervision in a minimal footprint. The R22 variant specifically denotes the 2.18V threshold setting, distinguishing it from other voltage options within the same family.

Supervisors Replacement Considerations

Direct substitutes include other ADM181x variants with similar thresholds, such as ADM1816-R22ARTZ-RL. Cross-reference with ADM1816-R22ARTZ-R7 for packaging differences. Verify pinout compatibility before substitution.
