MAX802MCSA+ Equivalent & Substitute Parts

Part Overview

The MAX802MCSA+ is a single-channel supervisor integrated circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for battery backup circuit applications. This component operates as a push-pull, totem pole output supervisor with active-low reset functionality and a 140ms minimum reset timeout. The part is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. Substitute parts must maintain compatibility across voltage monitoring thresholds, output topology, reset polarity, and package specifications to ensure functional equivalence in battery backup and power management applications.

Substitute Part Grouping Explanation

Substitute parts for the MAX802MCSA+ are categorized based on strict parameter alignment. The primary substitution criteria are:

Critical Parameters for Substitution:

Voltage threshold: 4.4V
Number of voltages monitored: 1 channel
Reset timeout: 140ms minimum
Package type: 8-SOIC (0.154", 3.90mm Width)
Mounting type: Surface Mount

Output Topology Consideration: The MAX802MCSA+ features push-pull, totem pole output with active-low reset. Direct parametric equivalents maintain this output configuration. Parts with open-drain or open-collector output (LTC692 series) represent functional alternatives but require circuit design verification due to output topology differences.

Temperature Range Variation: The main part operates at 0°C ~ 70°C. Substitute parts with extended temperature ranges (-40°C ~ 85°C) provide broader operational capability and are suitable for applications requiring wider temperature support.

Engineering Selection Recommendations

Direct Parametric Equivalents (Recommended Primary Substitutes):

MAX692ACSA+ and MAX704CSA+ are active-status direct parametric equivalents with identical electrical specifications and package configuration. Both maintain push-pull, totem pole output topology and active-low reset polarity. These parts are suitable for direct replacement in existing designs without circuit modification.

ADM692AARNZ and ADM692AARNZ-REEL extend the operating temperature range to -40°C ~ 85°C while maintaining all other critical parameters. ADM692AARNZ-REEL offers significantly higher inventory availability (50100 Pcs) and is packaged in Cut Tape & Digi-Reel format, providing supply chain advantages for production volumes.

STM802MM6F, manufactured by STMicroelectronics, provides an alternative source with identical electrical specifications and extended temperature range (-40°C ~ 85°C). This part maintains push-pull, totem pole output and active-low reset configuration.

Functional Alternatives (Output Topology Difference):

LTC692 series parts (LTC692CS8#PBF, LTC692CS8#TRPBF, LTC692IS8#PBF, LTC692IS8#TRPBF) feature open-drain or open-collector output instead of push-pull, totem pole topology. These parts maintain the 4.4V threshold and 140ms reset timeout but require circuit design evaluation to confirm compatibility with existing pull-up resistor networks and load requirements. The LTC692IS8 variants support extended temperature range (-40°C ~ 85°C).

Compliance & Certification:

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can MAX692ACSA+ directly replace MAX802MCSA+ without circuit modification?

A: Yes. MAX692ACSA+ is a direct parametric equivalent with identical voltage threshold (4.4V), output topology (push-pull, totem pole), reset polarity (active low), reset timeout (140ms minimum), and 8-SOIC package. No circuit modification is required.

Q: What is the difference between ADM692AARNZ and ADM692AARNZ-REEL?

A: Both parts are electrically identical with identical specifications. The primary difference is packaging format: ADM692AARNZ is supplied in Tube packaging, while ADM692AARNZ-REEL is supplied in Cut Tape & Digi-Reel format. ADM692AARNZ-REEL offers higher inventory availability (50100 Pcs vs. 1523 Pcs) and is preferred for production volume applications.

Q: Why do LTC692 parts have different output topology?

A: LTC692 series supervisors feature open-drain or open-collector output configuration, whereas MAX802MCSA+ uses push-pull, totem pole output. While both topologies can perform reset supervision, the open-drain configuration requires external pull-up resistors and may have different drive characteristics. Circuit design verification is necessary before substitution.

Q: Can I use a part with extended temperature range (-40°C ~ 85°C) in place of the standard range (0°C ~ 70°C)?

A: Yes. Extended temperature range parts (ADM692AARNZ, ADM692AARNZ-REEL, LTC692IS8#PBF, LTC692IS8#TRPBF, STM802MM6F) are backward compatible with applications requiring only 0°C ~ 70°C operation. The extended range provides additional operational margin and is suitable for broader environmental conditions.

Q: Is STM802MM6F from a different manufacturer compatible?

A: Yes. STM802MM6F, manufactured by STMicroelectronics, maintains all critical electrical parameters: 4.4V threshold, push-pull totem pole output, active-low reset, 140ms timeout, and 8-SOIC package. It is a cross-manufacturer equivalent suitable for applications requiring alternative sourcing.

Q: What packaging options are available for production?

A: Tube packaging is available for MAX802MCSA+, MAX692ACSA+, MAX704CSA+, ADM692AARNZ, LTC692CS8#PBF, and LTC692IS8#PBF. Tape & Reel (TR) and Cut Tape & Digi-Reel packaging is available for ADM692AARNZ-REEL, LTC692CS8#TRPBF, LTC692IS8#TRPBF, and STM802MM6F. Select packaging based on production volume and assembly requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating, meeting standard environmental and manufacturing requirements.
