MAX6651EEE Equivalent & Substitute Parts

Part Overview

The MAX6651EEE is a Brushless DC (BLDC) motor driver controller with I2C interface, designed for fan control applications in the 3V to 5.5V supply voltage range. Operating across -40°C to 85°C, this 16-QSOP surface mount device functions as a speed controller with pre-driver low-side output configuration. The MAX6651EEE is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX6651EEE are identified based on strict electrical and mechanical parameter matching. The primary substitution criterion is functional equivalence across the following parameters:

• Motor control type: Brushless DC (BLDC)
• Control interface: I2C communication protocol
• Output stage configuration: Pre-driver low-side topology
• Supply voltage compatibility: 3V to 5.5V operating range
• Thermal operating window: -40°C to 85°C
• Physical form factor: 16-SSOP package with 0.154" width (3.90mm)
• Surface mount compatibility

The MAX6651EEE+ qualifies as a direct substitute based on identical electrical specifications and package geometry, with the distinction of active product status and improved compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX6651EEE+ serves as the direct functional equivalent for MAX6651EEE applications. Both devices share identical electrical specifications, I2C interface protocol, BLDC motor control architecture, and 16-SSOP package geometry, ensuring pin-for-pin and functional compatibility.

The MAX6651EEE+ is preferred for new designs and ongoing production due to active product status and ROHS3 compliance certification. The original MAX6651EEE, classified as obsolete, presents supply chain constraints and lacks current environmental compliance documentation.

For systems currently utilizing MAX6651EEE, substitution with MAX6651EEE+ requires no circuit modifications, as all electrical parameters and pinout remain identical. Packaging format differs only in supplier delivery method (tube for MAX6651EEE+), which does not affect component functionality or board-level integration.

Frequently Asked Questions (FAQ)

Q: Are MAX6651EEE and MAX6651EEE+ pin-for-pin compatible?

A: Yes. Both devices utilize the 16-SSOP package with identical pinout and electrical specifications. Direct substitution on existing PCB layouts is supported without design modification.

Q: What is the primary difference between MAX6651EEE and MAX6651EEE+?

A: The MAX6651EEE+ is the active production variant with ROHS3 compliance certification. The MAX6651EEE is obsolete. Electrical performance and package geometry are identical.

Q: Can MAX6651EEE+ replace MAX6651EEE in existing applications?

A: Yes. Identical I2C interface, BLDC motor control function, voltage supply range (3V-5.5V), operating temperature window (-40°C to 85°C), and 16-SSOP package ensure full functional equivalence.

Q: Does the packaging format difference affect component selection?

A: No. The tube packaging of MAX6651EEE+ is a supplier delivery format only. Component electrical characteristics and PCB mounting remain unchanged.

Q: What compliance certifications apply to each variant?

A: MAX6651EEE carries RoHS non-compliant status. MAX6651EEE+ is ROHS3 compliant. Both are REACH unaffected and classified under ECCN EAR99.
