BU6906GF-TL Equivalent & Substitute Parts

Part Overview

The BU6906GF-TL is a motor driver integrated circuit manufactured by Rohm Semiconductor, designed for brushless DC (BLDC) motor applications. This device integrates control and power stages in a compact 6-SSOF package, operating across a 1.8V to 5.5V supply voltage range with 800mA output current capability. The BU6906GF-TL is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BU6906GF-TL are identified based on strict electrical and mechanical compatibility criteria. The following parameters determine valid substitution:

• Output Configuration: Half Bridge (2)
• Interface: PWM
• Technology: Power MOSFET
• Voltage - Supply: 1.8V ~ 5.5V
• Mounting Type: Surface Mount
• Package / Case: 6-SMD, Flat Leads
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Two substitute parts meet these criteria with variations in product status, packaging format, and output current specifications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are manufactured by Rohm Semiconductor and maintain ROHS3 compliance and MSL Level 1 ratings, ensuring regulatory and environmental compatibility with the original BU6906GF-TL.

The BU6909AGFT-TL is classified as active and provides direct electrical equivalence with identical output current (800mA) and operating temperature range (-40°C ~ 125°C). The primary difference is packaging format: the BU6909AGFT-TL is supplied in Tape & Reel (TR) format with 6-TSSOF package designation, compared to the original 6-SSOF package.

The BD69060GFT-TL is manufacturer-recommended and also maintains active product status. This part offers increased output current capability (1A versus 800mA) and operates within the same supply voltage range. The operating temperature maximum is reduced to 105°C, and the load voltage range differs (0.16V ~ 5V). This part is suitable for applications requiring higher current delivery within the specified thermal constraints.

Frequently Asked Questions (FAQ)

Q: Can BU6909AGFT-TL directly replace BU6906GF-TL in existing designs?

A: The BU6909AGFT-TL provides electrical equivalence with identical current and temperature specifications. The primary consideration is package format: BU6909AGFT-TL uses 6-TSSOF packaging versus the original 6-SSOF. Both are 6-SMD, Flat Leads surface mount packages. PCB layout compatibility must be verified against specific package dimensions.

Q: What are the key differences between BU6909AGFT-TL and BD69060GFT-TL?

A: Both parts maintain PWM interface and half-bridge output configuration. BU6909AGFT-TL matches the original 800mA output current and -40°C ~ 125°C operating range. BD69060GFT-TL provides 1A output current but operates to a maximum of 105°C and has a different load voltage range (0.16V ~ 5V versus 1.8V ~ 5.5V). Selection depends on application current requirements and thermal operating conditions.

Q: Are all substitute parts RoHS compliant?

A: Yes. BU6906GF-TL, BU6909AGFT-TL, and BD69060GFT-TL are all ROHS3 compliant with MSL Level 1 rating, meeting current environmental and regulatory requirements.

Q: Why is the original BU6906GF-TL obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. Active alternatives are available from the same manufacturer with equivalent or enhanced specifications, ensuring design continuity.

Q: What is the significance of the packaging format difference (6-SSOF versus 6-TSSOF)?

A: Both are 6-pin surface mount packages with flat leads. The specific package designation indicates minor dimensional or lead configuration differences. PCB footprint compatibility must be confirmed through package datasheets before implementation.
