MAX1660EEE Battery Monitor IC - Equivalent & Substitute Parts

Part Overview

The MAX1660EEE is a Battery Monitor IC designed for fuel gauge applications in 16-QSOP surface mount packaging. This component provides battery monitoring functionality with over-current and short-circuit fault protection via I2C interface. The MAX1660EEE is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX1660EEE is determined by strict equivalence across the following parameters:

• Functional Equivalence: Battery Monitor function with identical I2C interface
• Fault Protection: Over-current and short-circuit protection capability
• Thermal Specification: Operating temperature range -40°C ~ 85°C (TA)
• Package Compatibility: 16-SSOP (0.154", 3.90mm Width) / 16-QSOP footprint
• Mounting Technology: Surface mount configuration
• Moisture Sensitivity: MSL 1 (Unlimited)

The MAX1660EEE+ meets all these criteria as a parametric equivalent from the same manufacturer base product line (MAX1660 series).

Parameter Comparison

Engineering Selection Recommendations

The MAX1660EEE+ is the direct active substitute for the obsolete MAX1660EEE. Both components share identical electrical specifications, thermal ratings, and mechanical packaging. The primary distinction is product status and regulatory compliance.

For new designs and production transitions, the MAX1660EEE+ is the appropriate selection due to its active product status and ROHS3 compliance. The obsolete MAX1660EEE should be phased out in favor of the MAX1660EEE+ to ensure long-term supply chain stability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the MAX1660EEE+ be used as a direct replacement for the MAX1660EEE?

A: Yes. The MAX1660EEE+ is a parametric equivalent with identical electrical function, interface, fault protection, operating temperature range, and 16-QSOP package footprint. Pin-for-pin compatibility is maintained.

Q: What is the primary reason to transition from MAX1660EEE to MAX1660EEE+?

A: The MAX1660EEE is classified as obsolete, while the MAX1660EEE+ maintains active product status. Additionally, the MAX1660EEE+ is ROHS3 compliant, whereas the MAX1660EEE is RoHS non-compliant.

Q: Are there any thermal or environmental differences between these parts?

A: No. Both parts operate across the identical temperature range of -40°C ~ 85°C (TA) and share the same moisture sensitivity level (MSL 1 - Unlimited).

Q: Is the 16-QSOP package footprint identical between both parts?

A: Yes. Both the MAX1660EEE and MAX1660EEE+ use the 16-SSOP (0.154", 3.90mm Width) package with 16-QSOP supplier device package designation. PCB layout and assembly processes remain unchanged.

Q: Are there any supply chain considerations?

A: The MAX1660EEE+ has active inventory status, ensuring ongoing availability. The MAX1660EEE, being obsolete, faces potential supply constraints and should not be specified for new production.
