ADM1816-5ARTZ-RL7

Supervisors Overview

The ADM1816-5ARTZ-RL7 is a voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a maximum supply voltage of 5.5 V and features a fixed threshold voltage of 3.06 V, corresponding to the '5' designation in its model number which typically indicates a 3.0V class tolerance range (2.5V, 3V, 3.3V, 5V options available in series). The device provides a reset delay time of 250 ms and utilizes an open-drain or push-pull output type. It is housed in a SOT-23-3 surface-mount package and supports manual reset functionality.

Supervisors Feature Summary

• Provides reliable power-on reset generation with a fixed 250 ms delay timer
• Offers flexible output configuration supporting both open-drain and push-pull modes
• Designed for single-input voltage monitoring applications without watchdog or backup battery switching

Supervisors Applications

• Microprocessor system power supervision
• Portable equipment voltage monitoring
• Battery-operated device reset control

Supervisors Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm the specific suffix 'RL7' denotes reel packaging if required for assembly processes. Check current availability status as distribution may vary by region. Ensure RoHS compliance documentation is obtained prior to integration into regulated products.

Supervisors Selection Notes

Select this part when a fixed 3.06 V threshold is required for systems operating up to 5.5 V. Choose the SOT-23-3 package for space-constrained designs. Opt for this variant over ADM1817 if open-drain/push-pull flexibility is needed rather than fixed push-pull. Verify that the 250 ms delay meets system startup timing requirements.

Supervisors Part Context

This component belongs to the ADM1816 series of voltage supervisors from Analog Devices. It shares functional similarities with the ADM1817 but differs in output stage capabilities and package options. The series is designed for low-power applications requiring precise voltage monitoring and controlled reset assertion times.

Supervisors Replacement Considerations

ADM1816-5AKSZ-RL7 offers similar functionality in an SC-70-3 package. ADM1817-5ARTZ-RL7 provides a fixed push-pull output in the same SOT-23-3 package. Verify pinout compatibility and output drive characteristics before substitution.
