BD6671FM-E2 Equivalent & Substitute Parts

Part Overview

The BD6671FM-E2 is a fully integrated motor driver IC manufactured by Rohm Semiconductor, designed for brushless DC (BLDC) motor control applications. This device integrates both control and power stage functionality with three half-bridge output configurations, operating within a 4.5V to 5.5V supply voltage range. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BD6671FM-E2 is determined by the following critical parameters:

• Motor driver type and output configuration (Half Bridge with 3 outputs for BLDC control)
• Fully integrated control and power stage architecture
• Parallel interface compatibility
• Power MOSFET technology implementation
• Surface mount packaging capability
• Compliance certifications (RoHS, REACH, ECCN classification)

The TPD4207F,FQ from Toshiba Semiconductor and Storage shares the core functional architecture (fully integrated BLDC motor driver with half-bridge output configuration and parallel interface) and equivalent technology platform (Power MOSFET). Both devices maintain surface mount implementation and equivalent compliance profiles. However, critical electrical parameter differences exist that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The TPD4207F,FQ is an active product with current manufacturing support, providing supply chain continuity advantages over the obsolete BD6671FM-E2. Both devices maintain equivalent RoHS compliance status and identical ECCN classification (EAR99), supporting consistent regulatory and export documentation requirements.

Critical electrical parameter differences require application-level evaluation:

• Supply voltage range differs significantly (4.5V-5.5V versus 14.6V-16.5V)
• Output current capability is doubled in the substitute (5A versus 2.5A)
• Load voltage range is substantially higher (50V-450V versus 3V-14V)
• Package footprint increases from 28-SOP to 30-SOP

Selection of the TPD4207F,FQ is appropriate only when the target application operates within the substitute's specified voltage and current parameters. Direct pin-for-pin replacement is not guaranteed due to package size differences and potential pinout variations.

Frequently Asked Questions (FAQ)

Q: Can the TPD4207F,FQ directly replace the BD6671FM-E2 in existing designs?

A: Direct replacement requires verification of three factors: (1) PCB layout accommodation of the larger 30-SOP package versus the original 28-SOP, (2) application supply voltage compatibility with the 14.6V-16.5V range, and (3) confirmation of pinout equivalence through detailed datasheet comparison.

Q: What are the primary substitution criteria for BLDC motor driver ICs?

A: Substitution eligibility is determined by matching output configuration (half-bridge topology), control architecture (fully integrated with parallel interface), technology platform (Power MOSFET), and electrical parameter ranges that encompass the original application requirements.

Q: Why does the TPD4207F,FQ have higher voltage and current ratings?

A: The TPD4207F,FQ is designed for higher-power BLDC motor applications. These enhanced specifications do not prevent use in lower-power applications, provided the device is properly configured and thermal management is adequate.

Q: Are there compliance or certification concerns with substitution?

A: Both devices maintain equivalent RoHS compliance status and EAR99 ECCN classification. Moisture sensitivity levels are identical (MSL 3, 168 Hours), supporting equivalent handling and storage requirements.

Q: What package considerations apply to this substitution?

A: The substitute uses a 30-SOP package (11.00mm width) compared to the original 28-SOP (7.50mm width). PCB layout redesign is necessary, and thermal tab configurations may differ, requiring thermal analysis validation.
