BU6904GF-GTL Equivalent & Substitute Parts

Part Overview

The BU6904GF-GTL is a motor driver power MOSFET PWM integrated circuit manufactured by Rohm Semiconductor, designed for brushless DC (BLDC) motor applications with a supply voltage range of 1.8V to 5.5V. This component functions as a fully integrated driver with control and power stage in a half-bridge configuration, delivering 800mA output current. 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 BU6904GF-GTL is determined by the following critical parameters:

• Motor type compatibility: Brushless DC (BLDC) operation
• Output configuration: Half Bridge (2) topology
• Interface protocol: PWM control
• Supply voltage range: 1.8V ~ 5.5V minimum overlap
• Output current capability: 800mA or greater
• Mounting type: Surface Mount
• Package footprint: 6-SMD, Flat Leads configuration
• Functional integration: Fully integrated driver with control and power stage
• Compliance standards: ROHS3 Compliant, MSL 1

Two substitute parts meet these criteria with variations in product status and thermal operating range.

Parameter Comparison

Engineering Selection Recommendations

BU6909AGFT-TL is classified as a parametric equivalent substitute. This part maintains identical electrical specifications including 800mA output current, 1.8V to 5.5V supply voltage, and -40°C to 125°C operating temperature range. The component is currently in active production status, ensuring long-term availability and supply chain stability. The package variant transitions from 6-SSOF to 6-TSSOF, both maintaining 6-SMD flat lead configuration compatibility. ROHS3 compliance and MSL 1 rating are preserved.

BD69060GFT-TL is designated as the manufacturer-recommended substitute. This part provides increased output current capability at 1A compared to the 800mA specification of the original component. Supply voltage range remains identical at 1.8V to 5.5V. The operating temperature range is reduced to -40°C to 105°C, which may be a limiting factor for applications requiring the full 125°C thermal performance of the original part. Load voltage range extends to 0.16V minimum. This component is in active production status with robust inventory availability. ROHS3 compliance and MSL 1 rating are maintained.

Both substitutes are manufactured by Rohm Semiconductor and carry identical compliance certifications (ROHS3, REACH Unaffected, EAR99 ECCN classification).

Frequently Asked Questions (FAQ)

Q: Can BU6909AGFT-TL directly replace BU6904GF-GTL in existing designs?

A: Yes. BU6909AGFT-TL maintains all critical electrical parameters: 800mA output current, 1.8V to 5.5V supply voltage, half-bridge configuration, PWM interface, and -40°C to 125°C operating temperature. The package transition from 6-SSOF to 6-TSSOF does not affect footprint compatibility as both use 6-SMD flat lead configuration. Active production status ensures supply continuity.

Q: What is the primary difference between BU6909AGFT-TL and BD69060GFT-TL?

A: BU6909AGFT-TL maintains the original 800mA output current specification and full -40°C to 125°C thermal range. BD69060GFT-TL provides higher output current at 1A but operates to a maximum of 105°C. Selection depends on application current requirements and thermal operating envelope.

Q: Are package changes between 6-SSOF and 6-TSSOF significant?

A: Both packages maintain 6-SMD flat lead configuration and are compatible with standard surface mount assembly processes. The TSSOF variant is a tape and reel packaging format, which is standard for high-volume production. PCB footprint compatibility is maintained.

Q: Do the substitute parts maintain compliance certifications?

A: Yes. Both BU6909AGFT-TL and BD69060GFT-TL are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification, matching the original BU6904GF-GTL certifications.

Q: Which substitute should be selected for new designs?

A: BU6909AGFT-TL is recommended for direct replacement applications requiring identical electrical specifications and thermal performance. BD69060GFT-TL is suitable for applications where increased output current (1A) is beneficial and the reduced maximum operating temperature (105°C) does not present a constraint.
