MAX692CPA Equivalent & Substitute Parts

Part Overview

The MAX692CPA is a single-channel supervisor integrated circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for battery backup circuit applications. This device monitors a single voltage threshold at 4.4V and provides push-pull, totem pole output with active-low reset functionality. The MAX692CPA is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain compatibility across voltage monitoring, output topology, reset polarity, and package specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX692CPA is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Single voltage monitoring channel
• 4.4V voltage threshold
• 8-DIP (0.300", 7.62mm) package
• Through-hole mounting type
• Output topology (push-pull, totem pole preferred for direct replacement)
• Reset polarity (active-low preferred for direct replacement)

Acceptable Variation Parameters:

• Operating temperature range (may exceed original specification)
• Reset timeout (may differ from 35ms minimum)
• Product status (active parts preferred over obsolete)
• RoHS compliance (ROHS3 compliant parts acceptable)
• Packaging format (tube acceptable)

Substitute parts are grouped into two categories: direct replacements (identical output topology and reset polarity) and functional alternatives (different output topology requiring circuit evaluation).

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Preferred):

MAX692CPA+ is the primary direct replacement. This part maintains identical electrical specifications including push-pull totem pole output, active-low reset polarity, and 35ms minimum reset timeout. The MAX692CPA+ is active in production status and ROHS3 compliant, addressing the obsolescence of the original MAX692CPA. Operating temperature range remains 0°C ~ 70°C (TA), matching the original specification.

Extended Temperature Range Alternatives:

ADM692ANZ and ADM692AANZ provide extended operating temperature ranges (-40°C ~ 85°C) while maintaining the same voltage threshold, output topology, and active-low reset polarity. ADM692ANZ retains the 35ms minimum reset timeout, providing the closest functional match to the original MAX692CPA with enhanced temperature performance. ADM692AANZ extends the reset timeout to 140ms minimum, suitable for applications requiring longer reset pulse duration.

Functional Alternative (Output Topology Variation):

LTC692CN8#PBF differs in output topology, providing open drain or open collector output instead of push-pull totem pole. This part is suitable only for applications where the circuit design accommodates open drain/open collector output configuration. The reset polarity is configurable (active high/active low), and reset timeout is 140ms minimum. Circuit-level evaluation is required before substitution.

Compliance Considerations:

All substitute parts are ROHS3 compliant, addressing environmental compliance requirements. The original MAX692CPA is RoHS non-compliant; designs requiring RoHS compliance must transition to one of the substitute parts.

Frequently Asked Questions (FAQ)

Q: Can MAX692CPA+ be used as a direct replacement for MAX692CPA?

A: Yes. MAX692CPA+ is a direct replacement, maintaining identical electrical specifications including 4.4V voltage threshold, push-pull totem pole output, active-low reset polarity, and 35ms minimum reset timeout. The primary difference is product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What is the difference between ADM692ANZ and ADM692AANZ?

A: Both parts provide extended operating temperature range (-40°C ~ 85°C) and maintain the 4.4V voltage threshold, push-pull totem pole output, and active-low reset polarity. The key difference is reset timeout: ADM692ANZ specifies 35ms minimum (matching MAX692CPA), while ADM692AANZ specifies 140ms minimum. Select ADM692ANZ for timing-critical applications requiring shorter reset pulses.

Q: Can LTC692CN8#PBF replace MAX692CPA in all applications?

A: LTC692CN8#PBF is a functional alternative only. The open drain or open collector output topology differs from the push-pull totem pole output of MAX692CPA. Substitution requires circuit-level evaluation to confirm compatibility with the application's output stage design and pull-up resistor configuration.

Q: Are all substitute parts available in the same 8-DIP package?

A: Yes. All substitute parts use the 8-DIP (0.300", 7.62mm) through-hole package, ensuring mechanical and electrical compatibility with existing PCB layouts designed for MAX692CPA.

Q: Which substitute part is recommended for new designs?

A: For new designs requiring RoHS compliance and active product status, ADM692ANZ is recommended. It provides extended operating temperature range (-40°C ~ 85°C), maintains the 35ms minimum reset timeout of the original MAX692CPA, and offers superior long-term availability compared to the obsolete MAX692CPA.

Q: What is the impact of different reset timeout specifications?

A: Reset timeout determines the minimum duration of the reset pulse output. MAX692CPA and ADM692ANZ specify 35ms minimum, while ADM692AANZ and LTC692CN8#PBF specify 140ms minimum. Applications with timing-sensitive reset requirements must select parts matching the required reset pulse duration.
