ADM1817-5ARTZ-REEL

Supervisors Overview

The ADM1817-5ARTZ-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed as a reset generator IC. It operates within a maximum supply voltage of 5.5 V and features a threshold voltage of 5 V, with alternative options including 2.5 V, 3 V, and 3.3 V. The device provides a fixed reset delay time of 250 ms and utilizes a push-pull output type. It monitors a single input without manual reset or watchdog timer capabilities. The component is housed in an SOT-23-3 package for surface mount installation and functions within a temperature range of -40°C to +105°C.

Supervisors Feature Summary

• Provides automated system reset generation upon detection of power supply anomalies
• Features a push-pull output configuration for direct interface with digital logic
• Operates without requiring external components such as capacitors or resistors for basic function

Supervisors Applications

• Microprocessor and microcontroller power supply monitoring
• Battery-powered systems requiring reliable reset sequencing
• Embedded control circuits needing automatic recovery from brown-out conditions

Supervisors Procurement Notes

Verify the specific suffix and reel configuration against official Analog Devices documentation to ensure compatibility with manufacturing processes. Confirm that the 5 V threshold variant matches the target supply rail requirements. Check current availability status as distribution channels may indicate limited stock or discontinuation notices. Ensure RoHS compliance data aligns with regional regulatory standards before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a simple, low-pin-count solution is required for single-supervision applications. The push-pull output offers stronger drive capability compared to open-drain alternatives, simplifying pull-up resistor removal. Consider the 250 ms delay duration to ensure it meets the minimum stabilization time required by the downstream processor. Evaluate the SOT-23-3 footprint constraints against available PCB real estate during the design phase.

Supervisors Part Context

This part belongs to the ADM1817 series of supervisory circuits from Analog Devices. It shares architectural similarities with other members like the ADM1811 but differs in output stage characteristics. The series is categorized under PMIC supervisory solutions, focusing on cost-effective protection for digital systems without complex programmability or multi-voltage monitoring features found in higher-end counterparts.

Supervisors Replacement Considerations

Direct substitutes include the ADM1811-5ARTZ-REEL, though output types differ (open drain vs. push-pull). Verify pinout compatibility and electrical parameter alignment before substitution.
