ADM1817-5ARTZ-RL7

Supervisors Overview

The ADM1817-5ARTZ-RL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor power supply integrity. It operates within a maximum supply voltage of 5.5 V and features a push-pull output type. The device provides a reset delay time of 250 ms and has a specified quiescent current of 16 uA. It supports threshold voltages including 2.5 V, 3 V, 3.3 V, and 5 V, with an overvoltage threshold of 3.15 V for the 5 V variant. The component functions as a single-input reset generator without manual reset or watchdog timer capabilities. It is housed in an SOT-23-3 package and is rated for operation between -40 C and +105 C.

Supervisors Feature Summary

• Provides automated system reset generation upon detection of under-voltage conditions relative to specific threshold levels.
• Features a push-pull output stage capable of driving load currents directly without requiring external pull-up resistors.
• Includes a fixed internal reset delay timer to ensure stable power supply settling before asserting the reset signal.

Supervisors Applications

• Microprocessor and microcontroller power supply monitoring
• Battery-powered electronic systems requiring low standby current
• Industrial control circuits needing reliable voltage supervision

Supervisors Procurement Notes

Verify component authenticity through authorized distribution channels due to discontinued status. Confirm RoHS compliance documentation matches specific manufacturing lot requirements. Check datasheet revisions for any parameter updates affecting design-in compatibility. Ensure storage conditions adhere to moisture sensitivity level guidelines prior to assembly.

Supervisors Selection Notes

Select this component when a simple, low-current voltage supervisor with a push-pull output is required. Compare against alternatives if manual reset functionality or open-drain outputs are preferred. Verify that the 250 ms delay meets system startup timing constraints. Consider thermal performance within the SOT-23-3 package for high ambient temperature environments.
