MAX793TCSE-T Equivalent & Substitute Parts

Part Overview

The MAX793TCSE-T is a supervisor integrated circuit designed for power management applications, specifically functioning as a battery backup circuit monitor. This component operates as a single-channel voltage supervisor with open drain and push-pull output capabilities, housed in a 16-SOIC surface mount package.

The MAX793TCSE-T carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this supervisor circuit.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX793TCSE-T is determined by strict equivalence across the following critical parameters:

• Functional Type: Single-channel battery backup circuit supervisor
• Output Configuration: Open drain and push-pull output capability
• Reset Characteristics: Active high/active low reset with 140ms minimum timeout
• Voltage Monitoring: Single voltage threshold at approximately 3.09V
• Package Specification: 16-SOIC surface mount package with 0.154" width (3.90mm)
• Operating Temperature: 0°C to 70°C range
• Regulatory Compliance: ROHS3 compliant, REACH unaffected

The substitute part MAX793TCSE+T meets all these criteria, with the primary distinction being product status (active versus obsolete) and minor voltage threshold variation (3.075V versus 3.09V), which falls within acceptable tolerance for supervisor circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The MAX793TCSE+T serves as the direct substitute for the obsolete MAX793TCSE-T. Both components share identical functional specifications, package geometry, and regulatory compliance certifications. The substitute part maintains active product status with Analog Devices Inc./Maxim Integrated, ensuring ongoing availability and technical support.

The voltage threshold differential of 15mV (3.09V versus 3.075V) represents a negligible variation within standard supervisor circuit tolerances and does not impact functional equivalence for battery backup circuit applications. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements.

Selection of the MAX793TCSE+T is appropriate for new designs, production continuity, and replacement applications where the MAX793TCSE-T is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the MAX793TCSE+T directly replace the MAX793TCSE-T in existing designs?

A: Yes. Both components are functionally equivalent across all critical parameters including output configuration, reset characteristics, voltage monitoring capability, package specification, and operating temperature range. The parts are pin-compatible and electrically interchangeable.

Q: What is the significance of the voltage threshold difference between the two parts?

A: The voltage threshold variation of 15mV (3.09V to 3.075V) is within standard supervisor circuit tolerance and does not affect functional equivalence. Both thresholds operate within the same application range for battery backup circuit monitoring.

Q: Why is the MAX793TCSE-T listed as obsolete?

A: Product obsolescence reflects manufacturing lifecycle decisions by Analog Devices Inc./Maxim Integrated. The MAX793TCSE+T maintains active status and provides continued availability for equivalent functionality.

Q: Are there any packaging or mounting differences between these parts?

A: No. Both components use identical 16-SOIC surface mount packaging with 0.154" width (3.90mm). PCB footprints and assembly processes remain unchanged.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the MAX793TCSE-T and MAX793TCSE+T are ROHS3 compliant and REACH unaffected, satisfying equivalent environmental and regulatory requirements.
