ADM1816-20ARTZ-RL

Supervisors Overview

The ADM1816-20ARTZ-RL is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 2.55 V. The device provides an active low reset signal with a minimum timeout period of 100 ms. It utilizes an open drain or open collector output configuration and is housed in a compact SOT-23-3 package. The component supports surface mount installation and functions reliably across an industrial temperature range from -40°C to +105°C.

Supervisors Feature Summary

• Provides precise voltage supervision for microprocessor systems
• Generates active low reset signals upon power failure detection
• Ensures system stability through defined reset timeout periods

Supervisors Applications

• Microprocessor reset generation
• Voltage monitoring in embedded systems
• Power supply supervision circuits

Supervisors Procurement Notes

Verify the exact suffix ARTZ-RL against official Analog Devices documentation to confirm pinout, package type, and tape-and-reel specifications. Ensure compatibility with your PCB footprint and reflow profile requirements. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 2.55 V threshold is required for system supervision. Consider the open-drain output capability for flexible logic interfacing. Verify that the 100 ms minimum reset delay meets the target processor's startup timing requirements. Confirm the SOT-23-3 package fits the available board space constraints.

Supervisors Part Context

This part belongs to the ADM1816 series of supervisory circuits designed for reliable power management. It serves as a dedicated voltage monitor ensuring proper initialization of digital logic. The series offers various threshold options to accommodate different supply rail voltages commonly found in portable and industrial electronics applications.

Supervisors Replacement Considerations

Check for ADM1816 variants with different threshold voltages if the 2.55 V level is unsuitable. Verify equivalent parts from other manufacturers offering similar open-drain outputs and comparable reset delays. Ensure any substitute maintains the same SOT-23-3 footprint and operating temperature range.
