MAX705EPA Equivalent & Substitute Parts

Part Overview

The MAX705EPA is a power management integrated circuit (PMIC) functioning as a supervisor with push-pull, totem pole output configuration. This device monitors a single voltage channel and provides active-low reset functionality with a 140ms minimum reset timeout. The MAX705EPA is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. Substitute parts maintain identical or compatible electrical and mechanical specifications while offering active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX705EPA is determined by the following critical parameters:

• Voltage Threshold: 4.65V (all substitutes maintain this specification)
• Output Configuration: Push-Pull, Totem Pole (all substitutes maintain this specification)
• Reset Logic: Active Low (all substitutes maintain this specification)
• Package / Case: 8-DIP (0.300", 7.62mm) (all substitutes maintain this specification)
• Operating Temperature Range: -40°C to 85°C (TA) (all substitutes maintain this specification)
• Mounting Type: Through Hole (all substitutes maintain this specification)
• Number of Voltages Monitored: 1 (all substitutes maintain this specification)

Substitute parts are grouped into the following categories:

Direct Manufacturer Equivalent: MAX705EPA+ maintains identical base product number (MAX705) and all electrical parameters, with improved RoHS3 compliance and active product status.

Parametric Equivalents: MAX709LEPA+ and ADM709LANZ share identical electrical specifications and package configuration, with different base product numbers (MAX709 and ADM709 respectively) but maintain all critical substitution parameters.

Manufacturer Recommended Alternative: ADM705ANZ provides equivalent functionality with a single parameter variance: Reset Timeout of 160ms Minimum (compared to 140ms Minimum in the main part), representing a 20ms tolerance increase within acceptable engineering margins for supervisor applications.

Parameter Comparison

Engineering Selection Recommendations

MAX705EPA+ (Direct Equivalent): This part is the primary substitute for the obsolete MAX705EPA. It maintains identical electrical specifications, package configuration, and functional characteristics while offering active product status and RoHS3 compliance. Selection of MAX705EPA+ is appropriate for direct replacement in existing designs and new implementations requiring the MAX705 base product line.

MAX709LEPA+ (Parametric Equivalent): This part provides identical electrical performance and package specifications with active product status and RoHS3 compliance. The MAX709 base product number indicates a different device variant within the Analog Devices supervisor family. Selection is appropriate when MAX709 series availability or supply chain considerations favor this alternative.

ADM705ANZ (Manufacturer Recommended Alternative): This part is recommended by Analog Devices as an alternative supervisor solution. It maintains all critical electrical specifications with a single variance: Reset Timeout of 160ms Minimum compared to 140ms Minimum. This 20ms increase in reset timeout remains within acceptable operating margins for supervisor applications. The ADM705 base product number represents the ADI-branded variant. Selection is appropriate when ADM705 series availability or supply chain considerations are favorable.

ADM709LANZ (Parametric Equivalent): This part provides identical electrical performance and package specifications with active product status and RoHS3 compliance. The ADM709 base product number indicates the ADI-branded variant of the MAX709 series. Selection is appropriate when ADM709 series availability or supply chain considerations favor this alternative.

All substitute parts maintain RoHS3 compliance and active product status, addressing the obsolescence of the original MAX705EPA while preserving functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can MAX705EPA+ be used as a direct replacement for MAX705EPA?

A: Yes. MAX705EPA+ maintains identical electrical specifications, voltage threshold (4.65V), output configuration (push-pull, totem pole), reset logic (active low), reset timeout (140ms minimum), operating temperature range (-40°C to 85°C), and 8-DIP package configuration. The primary differences are active product status and RoHS3 compliance.

Q: What is the difference between MAX709LEPA+ and MAX705EPA+?

A: Both parts maintain identical electrical specifications and package configuration. The difference is the base product number: MAX705 versus MAX709. Both are Maxim Integrated supervisor devices with active product status and RoHS3 compliance. Selection between these parts depends on supply chain availability and design requirements.

Q: Why does ADM705ANZ have a different reset timeout specification?

A: ADM705ANZ specifies a 160ms Minimum reset timeout compared to 140ms Minimum in MAX705EPA. This 20ms difference represents a tolerance variation within the ADM705 product specification. For applications requiring the exact 140ms timeout, MAX705EPA+, MAX709LEPA+, or ADM709LANZ are more appropriate selections.

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

A: Yes. All substitute parts (MAX705EPA+, MAX709LEPA+, ADM705ANZ, and ADM709LANZ) are packaged in 8-DIP (0.300", 7.62mm) through-hole configuration, maintaining identical mechanical compatibility with the original MAX705EPA.

Q: What is the significance of RoHS3 compliance in these substitute parts?

A: All substitute parts are RoHS3 compliant, whereas the original MAX705EPA is RoHS non-compliant. RoHS3 compliance indicates conformance to current environmental and hazardous substance restrictions, making these parts suitable for applications and markets requiring regulatory compliance.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, with the exception of ADM705ANZ in applications requiring the exact 140ms reset timeout specification. All other substitute parts (MAX705EPA+, MAX709LEPA+, and ADM709LANZ) maintain identical electrical and mechanical specifications and can be used interchangeably with MAX705EPA in existing designs.

Q: What is the difference between Maxim Integrated and Analog Devices branding on these parts?

A: Maxim Integrated (MAX series) and Analog Devices (ADM series) are both manufacturer brands under Analog Devices Inc. The MAX705/MAX709 and ADM705/ADM709 series represent equivalent supervisor products from these respective product lines. Electrical specifications and package configurations remain identical across branding variants.
