ADM1816-5ART-REEL7

Supervisors Overview

The ADM1816-5ART-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc. It functions as a microprocessor reset generator with a single monitored input and an open-drain or push-pull output type. The device operates within a maximum supply voltage of 5.5 V and features a reset delay time of 250 ms. It is available in SC-70-3 and SOT-23-3 packages, supporting threshold voltages including 2.5 V, 3 V, 3.3 V, and 5 V. The component lacks manual reset, watchdog timer, and battery backup switch functionalities.

Supervisors Feature Summary

• Provides reliable system reset generation for microprocessors upon power-up or voltage fault detection
• Offers flexible output configuration options including open-drain and push-pull modes
• Supports multiple standard threshold voltage selections to accommodate various supply rails

Supervisors Applications

• Microprocessor reset circuits
• Voltage supervisory systems
• Power management monitoring

Supervisors Procurement Notes

Verify the specific package variant (SC-70-3 or SOT-23-3) required for your design, as availability may vary between suffixes like ART and AKSZ. Confirm current stock status with authorized distributors, as some variants may be subject to limited supply or discontinuation notices. Ensure the selected threshold voltage matches your system's operating requirements before ordering.

Supervisors Selection Notes

Select this component when a simple, low-cost reset generator is needed without additional features like watchdog timers or manual resets. Consider the output drive capability and package size constraints relative to your PCB layout. Verify that the 250 ms reset delay meets your system's startup timing requirements. Check compatibility with the target microprocessor's reset input specifications.

Supervisors Part Context

This part belongs to the ADM1816 series of voltage supervisors from Analog Devices. It is functionally similar to the DS1816 series but may differ in specific electrical characteristics and packaging options. The series is designed for basic power monitoring applications where advanced features are not required.

Supervisors Replacement Considerations

The DS1816R-5+T&R is a comparable alternative from the same manufacturer family. Verify pinout compatibility and reset delay times before substitution. The ADM811LART-REEL7 offers push-pull output and manual reset but differs in package and delay characteristics.
