ADM1816-5ARTZ-REEL

Supervisors Overview

The ADM1816-5ARTZ-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring power supply integrity in electronic systems. It operates within a maximum supply voltage of 5.5 V and features a reset delay time of 250 ms. The device utilizes an SMD/SMT installation style in a SOT-23-3 package. It provides one monitored input with push-pull output capability. The component supports threshold voltages including 2.5 V, 3 V, 3.3 V, and 5 V, ensuring compatibility with various logic levels. It lacks manual reset, watchdog timer, and battery backup switch functions, operating across a temperature range from -40 C to +105 C.

Supervisors Feature Summary

• Provides automatic power supply supervision with push-pull output configuration
• Features a fixed 250 ms reset delay for stable system initialization
• Supports multiple standard threshold voltages for flexible design integration

Supervisors Applications

• Microprocessor system reset generation
• Power supply monitoring in embedded controllers
• Voltage supervision for digital logic circuits

Supervisors Procurement Notes

Verify the exact suffix and manufacturer documentation to confirm availability status, as distribution channels may indicate limited stock or discontinuation. Ensure the ordering part number matches the specific package and electrical parameters required for the target application. Cross-reference official datasheets for any recent product change notices that might affect pinout or functionality.

Supervisors Selection Notes

Select this component when a simple, low-pin-count voltage supervisor with a push-pull output is required. The fixed 250 ms delay suits applications where immediate reset upon undervoltage is not critical. Verify that the available threshold options align with the system's nominal supply voltage. Consider the SOT-23-3 package size constraints and thermal requirements during PCB layout.

Supervisors Part Context

This part belongs to the ADM1816 series of voltage supervisors from Analog Devices. It shares functional similarities with other parts in the family but differs in specific threshold configurations and package variants. The series is designed for cost-sensitive applications requiring reliable power management without complex features like watchdog timers or manual reset buttons.
