MAX704SESA Equivalent & Substitute Parts

Part Overview

The MAX704SESA is a supervisor integrated circuit from Analog Devices Inc./Maxim Integrated, classified as a Power Management (PMIC) device. It functions as a battery backup circuit supervisor with push-pull, totem pole output configuration, monitoring a single voltage threshold at 2.925V. The device is currently listed as obsolete, which necessitates identification of functionally equivalent alternatives for new designs or component replacement in existing applications. Active substitute options are available from both the original manufacturer and alternative suppliers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX704SESA is determined by strict equivalence across the following critical parameters:

• Package / Case: 8-SOIC (0.154", 3.90mm Width) — physical and electrical compatibility requirement
• Number of Voltages Monitored: 1 — functional channel count
• Voltage - Threshold: 2.925V — voltage monitoring setpoint
• Output Configuration: Push-Pull, Totem Pole — output stage topology
• Reset Logic: Active Low — reset signal polarity
• Reset Timeout: 140ms Minimum — timing specification
• Operating Temperature Range: -40°C ~ 85°C (TA) — thermal operating envelope
• Mounting Type: Surface Mount — assembly compatibility

All substitute parts listed maintain these parameters identically. Differences in product status, RoHS compliance, and packaging format (tube vs. cut tape) do not affect functional equivalence but may impact procurement and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

MAX704SESA+ (Direct Manufacturer Equivalent)

The MAX704SESA+ is the direct successor from Analog Devices Inc./Maxim Integrated, maintaining identical electrical and mechanical specifications to the obsolete MAX704SESA. This part carries Active product status and achieves ROHS3 compliance, addressing regulatory requirements for new designs. Packaging is supplied in tube format. This option is preferred for applications requiring continuity with the original manufacturer's product line.

MAX690SESA+ (Parametric Equivalent)

The MAX690SESA+ is a parametric equivalent from Analog Devices Inc./Maxim Integrated, offering identical functional specifications with Active product status and ROHS3 compliance. The base product number differs (MAX690 vs. MAX704), but all critical electrical and mechanical parameters match. This part is supplied in tube packaging and represents an alternative within the same manufacturer's portfolio.

STM704SM6F (Cross-Manufacturer Equivalent)

The STM704SM6F from STMicroelectronics provides functional equivalence across all critical parameters, with Active product status and ROHS3 compliance. This part is supplied in Cut Tape (CT) & Digi-Reel® format, offering different procurement flexibility. Selection of this cross-manufacturer option may be driven by supply chain considerations, pricing, or existing STMicroelectronics component relationships.

Frequently Asked Questions (FAQ)

Q: Can MAX704SESA+ be used as a direct replacement for MAX704SESA?

A: Yes. The MAX704SESA+ maintains identical electrical specifications, package configuration, and functional behavior. The primary differences are product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. non-compliant). Pin-for-pin compatibility is confirmed.

Q: What is the difference between MAX704SESA+ and MAX690SESA+?

A: Both parts are from Analog Devices Inc./Maxim Integrated and share identical electrical and mechanical specifications. The base product number differs (MAX704 vs. MAX690), but this does not affect functional equivalence. Selection between them may depend on availability or existing design documentation.

Q: Is STM704SM6F a suitable replacement for MAX704SESA?

A: Yes. The STM704SM6F from STMicroelectronics meets all critical electrical and mechanical parameters: single voltage monitoring at 2.925V, push-pull totem pole output, active low reset with 140ms minimum timeout, 8-SOIC package, and -40°C to 85°C operating range. The primary difference is the supplier and packaging format (Cut Tape vs. tube).

Q: Does package format affect substitution compatibility?

A: Package format (tube, cut tape, or digi-reel) does not affect electrical or mechanical compatibility. Format selection is driven by procurement requirements, assembly processes, and inventory management. All listed substitutes use the identical 8-SOIC physical package.

Q: Are there RoHS compliance implications when substituting the obsolete MAX704SESA?

A: The original MAX704SESA is RoHS non-compliant. All active substitutes (MAX704SESA+, MAX690SESA+, STM704SM6F) are ROHS3 compliant. For new designs or applications subject to RoHS regulations, selection of a compliant substitute is required.

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

A: Yes, provided the PCB footprint accommodates the 8-SOIC (0.154", 3.90mm Width) package. All listed substitutes share identical pinout, electrical specifications, and package dimensions. No circuit modifications are required.
