ADM809-5LARTZ-RL7 Equivalent & Substitute Parts

Part Overview

The ADM809-5LARTZ-RL7 is a Power Management Integrated Circuit (PMIC) supervisor manufactured by Analog Devices Inc. It functions as a microprocessor unit (MPU) supervisor with push-pull, totem pole output configuration in a SOT-23-3 surface mount package. This device monitors a single voltage threshold at 4.63V and provides active-low reset functionality with a 30ms minimum reset timeout. The part is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility is required across manufacturing locations or procurement channels. Alternative supervisors with identical electrical specifications and package compatibility enable seamless design implementation without circuit modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADM809-5LARTZ-RL7 is determined by strict alignment of the following critical parameters:

• Voltage threshold: 4.63V (exact match required)
• Output configuration: Push-Pull, Totem Pole (exact match required)
• Reset logic: Active Low (exact match required)
• Package: SOT-23-3 / TO-236-3 / SC-59 (exact match required)
• Number of voltages monitored: 1 channel (exact match required)
• Mounting type: Surface Mount (exact match required)
• RoHS compliance: ROHS3 Compliant (minimum requirement)
• Moisture sensitivity: MSL 1 (minimum requirement)

All substitute parts listed below meet these mandatory criteria. Variations in reset timeout duration and operating temperature range are permissible provided the substitute part's specifications encompass or match the application requirements.

Parameter Comparison

Engineering Selection Recommendations

For new designs and production applications, prioritize substitute parts with Active product status: MAX6801UR46D2+T, MIC809LUY-TR, STM809LWX6F, and TCM809LVNB713. These parts ensure long-term availability and manufacturer support.

MAX6801UR46D2+T offers the shortest reset timeout (20ms) and extended operating temperature range (-40°C ~ 125°C), making it suitable for applications requiring faster reset response or operation in elevated temperature environments.

TCM809LVNB713 provides the widest operating temperature range (-40°C ~ 125°C) among active alternatives, supporting demanding thermal environments while maintaining full electrical equivalence.

MIC809LUY-TR and STM809LWX6F are suitable for standard industrial temperature range applications (-40°C ~ 85°C) with consistent 140ms reset timeout specifications.

Avoid APX809-46SAG-7 and MAX809LTRG for new designs due to "Not For New Designs" and "Obsolete" status designations, respectively. These parts present supply and long-term support risks.

All substitute parts maintain RoHS3 compliance and MSL 1 moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can I substitute the ADM809-5LARTZ-RL7 with any of the listed parts without circuit modification?

A: Yes, all listed substitute parts share identical voltage threshold (4.63V), output configuration (push-pull, totem pole), reset logic (active low), and package type (SOT-23-3). Direct pin-for-pin substitution is possible without circuit redesign.

Q: What is the significance of the reset timeout difference between the main part (30ms) and substitute parts (20ms to 140ms)?

A: Reset timeout defines the duration the supervisor holds the reset signal active after voltage threshold detection. The ADM809-5LARTZ-RL7 specifies 30ms minimum. Substitute parts with longer timeouts (140ms) provide extended reset assertion, which is acceptable for most applications. MAX6801UR46D2+T with 20ms timeout meets the requirement. Verify application-specific reset timing requirements before selection.

Q: Why is APX809-46SAG-7 marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and support for this part. While electrically equivalent, it presents supply chain risk and reduced manufacturer support. New designs should select from parts with Active status.

Q: What is the difference between operating temperature specifications listed as (TJ) versus (TA)?

A: TJ represents junction temperature (internal die temperature), while TA represents ambient temperature (external environment). Both specifications define the operating range. The ADM809-5LARTZ-RL7 specifies TJ range (-40°C ~ 150°C), providing broader thermal capability than most substitutes specifying TA range. Verify thermal management requirements for your application.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts maintain RoHS3 compliance and MSL 1 moisture sensitivity rating, meeting standard environmental and manufacturing requirements.

Q: Which substitute part offers the best long-term availability?

A: MAX6801UR46D2+T, MIC809LUY-TR, STM809LWX6F, and TCM809LVNB713 all carry Active product status, indicating ongoing manufacturer support and production. Among these, MAX6801UR46D2+T and TCM809LVNB713 offer extended operating temperature ranges (-40°C ~ 125°C), supporting broader application flexibility.
