ADM1816-5AKSZ-REEL

Supervisors Overview

The ADM1816-5AKSZ-REEL is a supervisory circuit manufactured by Analog Devices Inc., designed as a microprocessor reset generator. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 3.06 V, suitable for monitoring 3.3 V power rails. The device provides a reset output with a typical delay time of 250 ms. It is housed in an SC-70-3 surface-mount package and supports open-drain or push-pull output configurations. The component lacks manual reset, watchdog timer, and battery backup switch functionalities.

Supervisors Feature Summary

• Provides reliable voltage supervision for microprocessor systems
• Fixed threshold detection for standard logic supply voltages
• Compact surface-mount packaging for space-constrained designs

Supervisors Applications

• Monitoring 3.3 V power supplies in embedded systems
• Microprocessor reset generation in industrial control units
• Voltage supervision in consumer electronics devices

Supervisors Procurement Notes

Verify the specific suffix (REEL) against the required tape-and-reel quantity specifications from the manufacturer's official documentation. Confirm that the 3.06 V threshold aligns with the target system's voltage tolerance requirements. Ensure compatibility with the SC-70-3 footprint during PCB layout validation. Check current availability status through authorized distributors as supply constraints may apply.

Supervisors Selection Notes

Select this component when a fixed 3.06 V threshold is required for 3.3 V system monitoring without the need for adjustable settings. Consider the SC-70-3 package size for compact applications. Evaluate if the 250 ms reset delay meets the system's startup timing requirements. Verify that the absence of watchdog or manual reset features does not conflict with system safety protocols.

Supervisors Part Context

This part belongs to the ADM1816 series of supervisory circuits from Analog Devices. The series offers various threshold options for different voltage rails. The REEL designation indicates tape-and-reel packaging for automated assembly. The device is part of the broader portfolio of power management ICs focused on simple reset generation.

Supervisors Replacement Considerations

The DS1816R-5+T&R is a documented alternative within the same product family, offering similar functionality with a comparable threshold voltage.
