BD6345FV-E2 Equivalent & Substitute Parts

Part Overview

The BD6345FV-E2 is a fully integrated motor driver IC from ROHM Semiconductor designed for brushless DC (BLDC) motor applications, particularly fan motor control. This device integrates both control and power stages in a compact 20-LSSOP surface mount package, operating across a 5.5V to 17V supply range with 1.2A output current capability.

The BD6345FV-E2 carries a "Not For New Designs" product status, indicating that ROHM has discontinued active development and support for this component. This status necessitates identifying equivalent alternatives for ongoing production requirements, maintenance applications, or design transitions to current-generation solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the BD6345FV-E2 is determined by strict alignment across the following critical parameters:

Motor driver function with fully integrated control and power stages for BLDC motor applications; Half Bridge (3) output configuration; On/Off interface control; Power MOSFET technology; 1.2A output current rating; 5.5V to 17V supply and load voltage range; -40°C to 150°C operating temperature range; 20-LSSOP surface mount package; ROHS3 compliance; and MSL Level 1 rating.

The BD6345FV-E2 itself represents the parametric equivalent within this specification set. No alternative part numbers have been provided in the input data that meet all specified criteria for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The BD6345FV-E2 maintains ROHS3 compliance and MSL Level 1 rating, supporting unrestricted moisture handling and environmental compliance for industrial and consumer applications. Its "Not For New Designs" status reflects ROHM's product lifecycle management rather than functional obsolescence.

For applications currently using the BD6345FV-E2, the part remains available with 729 units in stock as new original inventory. Continued use of this component is technically viable where supply remains accessible. For new design initiatives or long-term production planning, consultation with ROHM Semiconductor regarding current-generation BLDC motor driver alternatives within the same functional category is appropriate.

Frequently Asked Questions (FAQ)

Q: What does "Not For New Designs" status mean for the BD6345FV-E2?

A: This status indicates that ROHM has concluded active development and marketing support for this component. Existing inventory remains available, and the part continues to function within its specified parameters. New design projects should evaluate current-generation alternatives.

Q: Can the BD6345FV-E2 be substituted with other BLDC motor drivers?

A: Direct substitution requires matching all critical parameters: Half Bridge (3) output configuration, 1.2A output current, 5.5V to 17V supply range, On/Off interface, 20-LSSOP package, and -40°C to 150°C operating temperature. Alternative parts must meet these specifications exactly.

Q: Is the 20-LSSOP package critical for substitution?

A: Yes. The 20-LSSOP (0.173", 4.40mm Width) package is a primary mechanical constraint. Substitutes must use identical or pin-compatible packaging to ensure PCB layout compatibility and assembly process alignment.

Q: What compliance certifications apply to the BD6345FV-E2?

A: The BD6345FV-E2 is ROHS3 compliant, REACH unaffected, and carries MSL Level 1 (unlimited moisture sensitivity). These certifications support use in regulated industrial and consumer applications without additional environmental restrictions.

Q: How does the 1.2A output current rating affect substitution?

A: The 1.2A rating defines the maximum motor load the driver can support. Substitutes must maintain this current specification to ensure equivalent motor control capability and thermal performance within the specified -40°C to 150°C operating range.
