MAX792LCPE Equivalent & Substitute Parts

Part Overview

The MAX792LCPE is a supervisor integrated circuit from Analog Devices Inc./Maxim Integrated, classified as a Power Management (PMIC) device. This component functions as a Simple Reset/Power-On Reset supervisor with push-pull output configuration, monitoring a single voltage channel with a 4.62V threshold. The MAX792LCPE is currently listed as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing system support and new design implementations. The availability of active substitute parts ensures continuity in applications requiring this supervisor topology.

Substitute Part Grouping Explanation

Substitution of the MAX792LCPE is determined by strict equivalence across the following critical parameters:

• Functional Type: Simple Reset/Power-On Reset supervisor topology
• Voltage Monitoring: Single channel configuration
• Voltage Threshold: 4.62V detection level
• Output Stage: Push-Pull output with Active High/Active Low reset capability
• Reset Timing: 140ms minimum timeout specification
• Thermal Range: 0°C to 70°C operating temperature
• Physical Package: 16-DIP through-hole form factor with 0.300" (7.62mm) body width
• Base Product Series: MAX792 family designation

The MAX792LCPE+ qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility across all monitored parameters. The primary distinction between the main part and substitute relates to product lifecycle status and compliance certifications rather than functional or physical characteristics.

Engineering Selection Recommendations

The MAX792LCPE+ is the direct functional equivalent for applications currently utilizing the MAX792LCPE. Selection of the MAX792LCPE+ is supported by the following engineering considerations:

Product Lifecycle: The MAX792LCPE is classified as obsolete, whereas the MAX792LCPE+ maintains active product status. Active status ensures ongoing manufacturer support, availability through authorized distribution channels, and compliance with current manufacturing standards.

Regulatory Compliance: The MAX792LCPE+ achieves ROHS3 compliance, meeting current environmental and hazardous substance restrictions. The original MAX792LCPE is non-compliant with RoHS requirements, which may present procurement and regulatory challenges in applications subject to RoHS directives.

Electrical and Mechanical Equivalence: All functional parameters, including voltage threshold, output configuration, reset timing, temperature range, and package dimensions, are identical between the two parts. Pin-for-pin compatibility is maintained, enabling direct substitution without circuit modification.

Packaging Availability: The MAX792LCPE+ is supplied in tube packaging format, which is standard for active production components and facilitates integration into automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the MAX792LCPE+ be used as a direct replacement for the MAX792LCPE in existing designs?

A: Yes. The MAX792LCPE+ is electrically and mechanically equivalent to the MAX792LCPE. All functional parameters, including voltage threshold (4.62V), output configuration (push-pull), reset timeout (140ms minimum), operating temperature range (0°C to 70°C), and 16-DIP package dimensions are identical. No circuit modifications are required for substitution.

Q: What is the primary reason to transition from MAX792LCPE to MAX792LCPE+?

A: The MAX792LCPE is obsolete, while the MAX792LCPE+ maintains active product status. Active status ensures availability, manufacturer support, and compliance with current regulatory standards including ROHS3. Obsolete parts face increasing supply constraints and may not meet modern procurement requirements.

Q: Are there any differences in pin configuration between these parts?

A: No. Both parts use the 16-PDIP package with identical pin assignments. The 0.300" (7.62mm) body width and through-hole mounting type are consistent across both variants.

Q: Does the MAX792LCPE+ meet RoHS compliance requirements?

A: Yes. The MAX792LCPE+ is ROHS3 compliant. The original MAX792LCPE is non-compliant with RoHS directives. Applications subject to RoHS requirements must use the MAX792LCPE+.

Q: What is the voltage monitoring capability of these supervisor ICs?

A: Both the MAX792LCPE and MAX792LCPE+ monitor a single voltage channel with a 4.62V threshold. The supervisor generates a reset signal when the monitored voltage falls below this threshold, with a minimum reset timeout of 140ms.

Q: Is the packaging format interchangeable between MAX792LCPE and MAX792LCPE+?

A: The electrical and functional characteristics are identical. The MAX792LCPE+ is supplied in tube packaging, which is standard for active components. Packaging format does not affect electrical performance or pin compatibility.
