ADM1817-R23ARTZ-R7

Supervisors Overview

The ADM1817-R23ARTZ-R7 is a voltage supervisory circuit manufactured by Analog Devices Inc. It monitors a single input voltage and provides a push-pull reset output. The device features a threshold voltage of 2.31 V and an overvoltage threshold of 2.37 V. It operates within a supply voltage range up to 5.5 V with a typical operating current of 16 uA. The reset delay time is specified at 100 ms minimum. The component is housed in a SOT-23-3 package and supports surface mount installation. It functions across a temperature range from -40°C to +105°C.

Supervisors Feature Summary

• Provides simple reset or power-on reset functionality for monitored power supplies
• Features active high reset output with push-pull drive capability
• Includes overvoltage detection threshold for enhanced system protection

Supervisors Applications

• Monitoring 2.5 V, 3 V, 3.3 V, and 5 V power supply voltages
• Embedded systems requiring reliable voltage supervision
• Portable electronic devices needing low standby current

Supervisors Procurement Notes

Verify the specific suffix ARTZ-R7 against official Analog Devices documentation to confirm pinout and packaging details. Confirm RoHS compliance status through the manufacturer's latest datasheet. Check for obsolescence notices as distribution availability may vary. Ensure the selected variant matches the required threshold voltage specifications for the target application design.

Supervisors Selection Notes

Select this component when a low-cost, low-power supervisor is needed for standard logic voltage levels. The SOT-23-3 package suits space-constrained designs. Verify that the 2.31 V threshold aligns with the specific rail being monitored. Consider the 16 uA quiescent current for battery-operated applications. Ensure the operating temperature range meets the environmental requirements of the end product.

Supervisors Part Context

This part belongs to the ADM1817 series of voltage supervisors from Analog Devices. The series offers various threshold options for different supply rails. The R7 suffix indicates reel packaging. These devices are designed for cost-sensitive applications requiring basic power management supervision without complex configuration interfaces.

Supervisors Replacement Considerations

Check Analog Devices documentation for direct cross-references. Variants like ADM1817-5ARTZ-R7 offer different thresholds. Ensure any substitute maintains the SOT-23-3 footprint and electrical characteristics.
