MAX802LCSA Equivalent & Substitute Parts

Part Overview

The MAX802LCSA is a Power Management Integrated Circuit (PMIC) supervisor with push-pull, totem pole output configuration. It monitors a single voltage channel with a 4.65V threshold and provides active-low reset functionality with a 140ms minimum timeout. The device is packaged in an 8-SOIC surface mount package and operates across the 0°C to 70°C temperature range.

The MAX802LCSA is classified as obsolete. Equivalent and substitute parts are available from Analog Devices Inc. and Linear Technology (now part of Analog Devices) that maintain functional compatibility while offering active product status and improved compliance certifications.

Substitute Part Grouping Explanation

Substitution of the MAX802LCSA is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Voltage threshold: 4.65V
Number of voltages monitored: 1 channel
Output configuration: Push-Pull, Totem Pole
Reset logic: Active Low
Package / Case: 8-SOIC (0.154", 3.90mm Width)
Mounting type: Surface Mount
Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

Reset timeout: Substitute parts may have different reset timeout specifications (35ms or 140ms minimum)
Operating temperature range: Substitute parts may support extended temperature ranges (-40°C ~ 85°C)
Product status: Active products are preferred over obsolete status
RoHS compliance: ROHS3 compliant alternatives are available
Packaging format: Tube, Cut Tape & Digi-Reel, or Tape & Reel formats

Substitute parts that maintain all mandatory matching parameters are electrically and mechanically compatible with the MAX802LCSA in battery backup circuit applications.

Engineering Selection Recommendations

Direct Electrical Equivalents (Push-Pull Output):

For applications requiring identical push-pull, totem pole output configuration with 140ms reset timeout and 0°C to 70°C operating range, select MAX690ACSA+ or MAX703CSA+. Both are active products with ROHS3 compliance.

For applications tolerant of extended operating temperature range (-40°C to 85°C), ADM690AARNZ, ADM690AARNZ-REEL, ADM802LARNZ, or ADM802LARNZ-REEL provide equivalent functionality with improved temperature performance and ROHS3 compliance.

Alternative Output Configuration:

LTC690CS8#PBF and LTC690CS8#TRPBF provide 4.65V threshold monitoring with active-low reset but feature open drain or open collector output instead of push-pull configuration. These are suitable only for applications where open drain output is acceptable. Reset timeout is 35ms minimum.

Faster Reset Timeout Alternative:

ADM8690ARNZ maintains push-pull output and extended temperature range but provides 35ms minimum reset timeout instead of 140ms. Selection requires confirmation that faster reset timing is compatible with system requirements.

Packaging Considerations:

MAX802LCSA+ is the direct variant of the obsolete MAX802LCSA with identical specifications and active product status, available in Tube packaging.

ADM690AARNZ-REEL and ADM802LARNZ-REEL are supplied in Tape & Reel format for high-volume manufacturing. ADM690AARNZ and ADM802LARNZ are supplied in Tube format for lower-volume applications.

Frequently Asked Questions (FAQ)

Q: Can I directly replace MAX802LCSA with MAX690ACSA+ or MAX703CSA+?

A: Yes. MAX690ACSA+ and MAX703CSA+ are parametric equivalents with identical voltage threshold (4.65V), output configuration (push-pull, totem pole), reset logic (active low), reset timeout (140ms minimum), operating temperature (0°C to 70°C), and package (8-SOIC). Both are active products with ROHS3 compliance.

Q: What is the difference between ADM690AARNZ and ADM802LARNZ?

A: Both parts are parametric equivalents with identical electrical specifications for the MAX802LCSA application. The primary difference is packaging format: ADM690AARNZ is supplied in Tube, while ADM802LARNZ is also supplied in Tube. Both support extended operating temperature (-40°C to 85°C) and are ROHS3 compliant.

Q: Can I use LTC690CS8#PBF as a substitute?

A: LTC690CS8#PBF maintains the 4.65V threshold and active-low reset but uses open drain or open collector output instead of push-pull, totem pole configuration. This part is suitable only if your circuit design accommodates open drain output. Reset timeout is 35ms minimum instead of 140ms.

Q: Why does ADM8690ARNZ have a different reset timeout?

A: ADM8690ARNZ provides 35ms minimum reset timeout compared to 140ms for the MAX802LCSA. This faster reset is a design variation. Selection requires confirmation that the application tolerates faster reset timing.

Q: What is the advantage of extended temperature range parts like ADM690AARNZ?

A: ADM690AARNZ and ADM802LARNZ support -40°C to 85°C operating temperature versus 0°C to 70°C for the MAX802LCSA. Extended temperature range is beneficial for industrial, automotive, or harsh environment applications. Electrical performance remains equivalent for the standard 0°C to 70°C range.

Q: Are all substitute parts ROHS3 compliant?

A: All active substitute parts listed are ROHS3 compliant. The original MAX802LCSA is RoHS non-compliant. If RoHS compliance is required, select from the active substitute parts.

Q: What packaging formats are available?

A: Substitute parts are available in Tube (standard packaging), Cut Tape & Digi-Reel (ADM690AARNZ-REEL), and Tape & Reel (ADM802LARNZ-REEL, LTC690CS8#TRPBF) formats. Selection depends on manufacturing volume and assembly process requirements.
