Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BD6775EFV-E2 is determined by the following critical parameters:

Core Functional Requirements:

• Bipolar stepper motor driver capability
• Fully integrated control and power stage
• Four half-bridge output configuration
• Parallel interface
• DMOS technology

Electrical Compatibility Criteria:

• Output current capability: minimum 500mA
• Supply voltage range: must accommodate 4.5V ~ 6V operation or higher
• Load voltage range: must support 10V ~ 37V
• Operating temperature range: -20°C to 150°C minimum

Physical & Compliance Requirements:

• Surface mount package with compatible pinout
• ROHS3 compliance
• MSL rating of 3 or better

Two substitute parts meet these criteria with varying degrees of parameter alignment and product status considerations.

Parameter Comparison

Engineering Selection Recommendations

BD63801EFV-E2 (Rohm Semiconductor): This part maintains identical package geometry (24-VSSOP) and pinout compatibility with the BD6775EFV-E2, enabling direct PCB substitution. Both devices share the same DMOS technology, output configuration, and interface architecture. The BD63801EFV-E2 carries Active product status with full compliance certifications. However, the supply voltage range (19V ~ 28V) differs significantly from the original part (4.5V ~ 6V), requiring circuit redesign for power supply architecture. This substitute is suitable only for applications where the higher supply voltage requirement can be accommodated.

TB62218AFG,C8,EL (Toshiba Semiconductor and Storage): This part provides superior output current capability (2A versus 500mA) and maintains supply voltage compatibility within the 4.75V ~ 5.25V range, overlapping with the original 4.5V ~ 6V specification. The load voltage range (10V ~ 38V) exceeds the original specification. The TB62218AFG,C8,EL carries Active product status with full compliance certifications. Package geometry differs (28-BSOP versus 24-VSSOP), requiring PCB layout modification and potential board redesign. This substitute is suitable for applications requiring higher output current or where package footprint changes are acceptable.

Both substitutes maintain core functional requirements: bipolar stepper motor driver capability, fully integrated control and power stage, four half-bridge configuration, parallel interface, DMOS technology, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the BD63801EFV-E2 be used as a direct drop-in replacement for the BD6775EFV-E2?

A: The BD63801EFV-E2 shares identical package geometry and pinout with the BD6775EFV-E2, enabling direct PCB substitution without layout modification. However, the supply voltage requirement (19V ~ 28V) differs from the original (4.5V ~ 6V), necessitating power supply circuit redesign. Electrical compatibility depends on your system's ability to provide the higher supply voltage.

Q: What are the key differences between the two Rohm substitutes?

A: The BD6775EFV-E2 operates from 4.5V ~ 6V supply with 500mA output current. The BD63801EFV-E2 operates from 19V ~ 28V supply with identical 500mA output current. Both share the same 24-VSSOP package and DMOS technology. Selection depends on your system's supply voltage architecture.

Q: Is the TB62218AFG,C8,EL compatible with existing PCB layouts designed for the BD6775EFV-E2?

A: No. The TB62218AFG,C8,EL uses a 28-BSOP package with different pin spacing (0.346" width versus 0.220" width) compared to the BD6775EFV-E2's 24-VSSOP package. PCB layout and footprint redesign is required. However, the supply voltage range (4.75V ~ 5.25V) aligns closely with the original specification.

Q: What is the significance of the higher output current rating on the TB62218AFG,C8,EL?

A: The TB62218AFG,C8,EL provides 2A output current capability versus 500mA on the BD6775EFV-E2. This higher current capacity allows driving stepper motors with greater torque requirements or lower coil resistance without thermal stress on the driver IC. Applications requiring higher motor performance benefit from this increased capability.

Q: Are all three parts RoHS3 compliant?

A: Yes. The BD6775EFV-E2, BD63801EFV-E2, and TB62218AFG,C8,EL are all ROHS3 compliant with MSL rating 3 (168 Hours), meeting current environmental and regulatory requirements.

Q: Why is the BD6775EFV-E2 marked "Not For New Designs"?

A: This designation indicates the part is in mature or end-of-life status within Rohm's product portfolio. The BD63801EFV-E2 and TB62218AFG,C8,EL both carry Active product status, making them suitable for new design implementations and long-term supply assurance.
