BA6665FM-E2 Equivalent & Substitute Parts

Part Overview

The BA6665FM-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 stages in a 28-HSOP surface mount package, operating within a 4.5V to 5.5V supply voltage range with a maximum output current of 1.3A. The product is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BA6665FM-E2 are identified based on the following critical parameters that define functional equivalence:

Motor driver architecture: Fully integrated control and power stage for BLDC motor applications Output configuration: Half bridge topology with three output stages Interface type: Parallel control interface Technology platform: Power MOSFET implementation Mounting and packaging: Surface mount construction with thermal management capability Regulatory compliance: RoHS compliance status

The TPD4207F,FQ from Toshiba Semiconductor and Storage shares the core architectural characteristics of the BA6665FM-E2, including fully integrated driver functionality, half-bridge output configuration, parallel interface, and power MOSFET technology. Both devices are designed for BLDC motor control in surface mount packages with equivalent moisture sensitivity ratings.

Parameter Comparison

Engineering Selection Recommendations

The TPD4207F,FQ is available as an active product from Toshiba, providing supply continuity for applications requiring BLDC motor driver functionality. Both the BA6665FM-E2 and TPD4207F,FQ maintain equivalent RoHS and moisture sensitivity compliance levels, supporting deployment in regulated environments.

Substitution feasibility depends on application-specific electrical requirements. The TPD4207F,FQ operates at higher supply voltage (14.6V ~ 16.5V versus 4.5V ~ 5.5V) and supports higher output current (5A versus 1.3A) and load voltage ranges (50V ~ 450V versus 3V ~ 14V). These differences require verification against system power supply architecture and motor load specifications before implementation.

Package geometry differs between the two devices: the BA6665FM-E2 uses a 28-SOP package while the TPD4207F,FQ uses a 30-SOP package. PCB layout modifications may be necessary to accommodate the larger package footprint of the substitute part.

Frequently Asked Questions (FAQ)

Q: Can the TPD4207F,FQ directly replace the BA6665FM-E2 in existing designs?

A: Direct replacement requires verification of three critical factors: supply voltage compatibility with system power rails, output current capability matching motor load requirements, and PCB layout accommodation for the larger 30-SOP package. The TPD4207F,FQ operates at significantly higher voltage and current ratings, which may not align with all legacy BA6665FM-E2 applications.

Q: What are the key differences between these two motor driver ICs?

A: Both devices share identical motor driver architecture (fully integrated BLDC control, half-bridge output, parallel interface, power MOSFET technology). Primary differences include supply voltage range (4.5V-5.5V versus 14.6V-16.5V), output current capability (1.3A versus 5A), load voltage range (3V-14V versus 50V-450V), and package size (28-SOP versus 30-SOP).

Q: Are there packaging considerations for substitution?

A: Yes. The TPD4207F,FQ package (30-SOP, 11.00mm width) is larger than the BA6665FM-E2 package (28-SOP, 7.50mm width). PCB redesign may be required to accommodate the increased package dimensions and pin count.

Q: What compliance certifications apply to both parts?

A: Both the BA6665FM-E2 and TPD4207F,FQ maintain RoHS compliance and equivalent moisture sensitivity levels (MSL 3, 168 hours), supporting use in regulated applications.

Q: Why is the BA6665FM-E2 classified as obsolete?

A: The BA6665FM-E2 is no longer in active production by Rohm Semiconductor. The TPD4207F,FQ from Toshiba represents an active alternative for new designs and ongoing system support.
