MAX693ACPE Equivalent & Substitute Parts

Part Overview

The MAX693ACPE is a single-channel supervisor integrated circuit designed for battery backup circuit applications within the Power Management (PMIC) category. This component operates as a push-pull output supervisor with active high/active low reset functionality and a 140ms minimum reset timeout. The MAX693ACPE is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing system support and new designs. Active alternatives with compatible electrical and mechanical specifications are available from Analog Devices Inc./Maxim Integrated and Analog Devices Inc.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX693ACPE are classified based on strict alignment with the following critical parameters:

Electrical Compatibility Criteria:

• Single-channel voltage monitoring capability
• 140ms minimum reset timeout
• Active high/active low reset functionality
• Through-hole 16-DIP mounting package (0.300", 7.62mm)
• Moisture Sensitivity Level 1 (Unlimited)

Substitution Categories:

Direct Substitutes (Identical Electrical Function): Parts maintaining the same voltage threshold (4.4V), output configuration (push-pull), and operating temperature range qualify as direct substitutes. These parts preserve all functional characteristics of the original component.

Compatible Substitutes (Equivalent Function with Parameter Variance): Parts with different voltage thresholds or extended operating temperature ranges remain functionally compatible when the application circuit design accommodates the parameter differences. Output configuration changes from push-pull to open drain require circuit-level evaluation but do not preclude substitution in appropriate applications.

Parameter Comparison

Engineering Selection Recommendations

MAX693ACPE+ (Direct Substitute): This part is the primary equivalent for the obsolete MAX693ACPE. It maintains identical electrical specifications including 4.4V voltage threshold, push-pull output configuration, and 0°C ~ 70°C operating temperature range. The MAX693ACPE+ is active in production status and ROHS3 compliant, making it the preferred choice for new designs and legacy system replacements where RoHS compliance is required.

MAX695CPE+ (Compatible Substitute): This part differs from the MAX693ACPE in voltage threshold specification (4.65V versus 4.4V). The MAX695CPE+ is active in production and ROHS3 compliant. Selection of this part requires circuit-level verification that the higher voltage threshold is compatible with system requirements.

ADM693AANZ (Extended Temperature Substitute): This part maintains the 4.4V voltage threshold and active high/active low reset functionality of the MAX693ACPE but extends the operating temperature range to -40°C ~ 85°C. The output configuration differs, with open drain primary output and push-pull secondary output. The ADM693AANZ is active in production and ROHS3 compliant. This part is suitable for applications requiring extended temperature operation, provided the open drain output configuration is compatible with the circuit design.

Frequently Asked Questions (FAQ)

Q: Can MAX693ACPE+ be used as a direct replacement for MAX693ACPE?

A: Yes. The MAX693ACPE+ maintains identical electrical and mechanical specifications including voltage threshold (4.4V), output configuration (push-pull), reset timeout (140ms minimum), and package format (16-DIP). The primary difference is product status (active versus obsolete) and RoHS compliance (ROHS3 compliant versus non-compliant).

Q: What is the key difference between MAX693ACPE and MAX695CPE+?

A: The voltage threshold differs. MAX693ACPE monitors at 4.4V, while MAX695CPE+ monitors at 4.65V. All other electrical and mechanical parameters remain identical. Circuit design must accommodate the higher threshold voltage.

Q: Is ADM693AANZ suitable for applications requiring the original MAX693ACPE specifications?

A: ADM693AANZ is compatible when the application circuit design accommodates two parameter differences: extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C) and output configuration (open drain primary output versus push-pull). The voltage threshold (4.4V) and reset timeout (140ms minimum) remain identical.

Q: Are all substitute parts available in the same 16-DIP package?

A: Yes. All substitute parts use the 16-DIP (0.300", 7.62mm) through-hole package format, ensuring mechanical compatibility with existing PCB designs.

Q: What is the RoHS compliance status of substitute parts?

A: MAX693ACPE+ and MAX695CPE+ are ROHS3 compliant. ADM693AANZ is also ROHS3 compliant. The original MAX693ACPE is RoHS non-compliant.

Q: Do all parts have the same moisture sensitivity level?

A: Yes. All parts, including the original MAX693ACPE and all substitutes, have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions.
