MP6543BGL-P Equivalent & Substitute Parts

Part Overview

The MP6543BGL-P is a multiphase motor driver PMIC manufactured by Monolithic Power Systems Inc., designed for brushless DC (BLDC) motor control applications. This fully integrated power stage and control device operates at 12V with 2A output current capability and features three half-bridge output configurations. The part is currently in active product status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to address packaging format availability, inventory requirements, and supply chain flexibility while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

All substitute parts for the MP6543BGL-P share the identical base product number MP6543 and maintain complete electrical and mechanical equivalence. Substitution is determined by the following parameters:

Electrical Equivalence Criteria:

• Output current: 2A
• Supply voltage range: 3V ~ 12V
• Operating temperature range: -40°C ~ 125°C (TJ)
• Output configuration: Half Bridge (3)
• Interface: PWM
• Technology: NMOS

Mechanical Equivalence Criteria:

• Package / Case: 24-VFQFN Exposed Pad
• Supplier Device Package: 24-QFN (3x4)
• Mounting Type: Surface Mount

Packaging Format Variations: Substitute parts differ only in packaging format designation (suffix letters) and tape/reel configuration:

• Cut Tape (CT) format: MP6543BGL-P, MP6543BGL-Z, MP6543GL-Z
• Tape & Reel (TR) format: MP6543AGL-P, MP6543AGL-Z, MP6543GL-P

All substitute parts maintain active product status, ROHS3 compliance, and REACH unaffected designation.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain full electrical and mechanical compatibility with the MP6543BGL-P. Selection between equivalent parts should be based on the following factors:

Packaging Format Requirements: Cut Tape (CT) format parts (MP6543BGL-P, MP6543BGL-Z, MP6543GL-Z) are suitable for manual assembly, prototyping, and low-volume production environments. Tape & Reel (TR) format parts (MP6543AGL-P, MP6543AGL-Z, MP6543GL-P) are optimized for automated pick-and-place assembly and high-volume manufacturing operations.

Compliance and Certification: All substitute parts carry identical regulatory compliance: ROHS3 compliant, REACH unaffected, and EAR99 ECCN classification. All parts maintain active product status with Monolithic Power Systems Inc., ensuring continued manufacturer support and availability.

Inventory and Supply Chain Considerations: MP6543GL-Z (Cut Tape format) maintains the highest inventory level at 55,200 pieces, providing maximum supply chain flexibility. MP6543AGL-Z (Tape & Reel format) offers 5,746 pieces for automated assembly environments. All other variants maintain inventory levels between 1,149 and 5,514 pieces.

Frequently Asked Questions (FAQ)

Q: Can MP6543AGL-P be used as a direct replacement for MP6543BGL-P?

A: Yes. Both parts are parametrically equivalent with identical electrical specifications (2A output current, 3V ~ 12V supply voltage, -40°C ~ 125°C operating temperature) and mechanical specifications (24-VFQFN Exposed Pad package, 24-QFN 3x4 form factor). The only difference is packaging format: MP6543AGL-P uses Tape & Reel (TR) format while MP6543BGL-P uses Cut Tape (CT) format.

Q: What is the difference between the suffix letters in MP6543 part numbers?

A: The suffix letters indicate packaging format and tape configuration. The "P" and "Z" designations represent different tape specifications within the same packaging category. The "AGL," "BGL," and "GL" designations represent different manufacturing or quality grade levels. All variants maintain identical electrical and mechanical performance.

Q: Are all MP6543 variants suitable for automated assembly?

A: Tape & Reel (TR) format parts (MP6543AGL-P, MP6543AGL-Z, MP6543GL-P) are optimized for automated pick-and-place assembly. Cut Tape (CT) format parts (MP6543BGL-P, MP6543BGL-Z, MP6543GL-Z) are suitable for manual assembly and lower-volume production. Verify your assembly equipment compatibility with the specific packaging format.

Q: Do all substitute parts meet the same regulatory requirements?

A: Yes. All MP6543 variants maintain ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification. All parts are manufactured by Monolithic Power Systems Inc. and carry active product status.

Q: What is the moisture sensitivity level for all MP6543 variants?

A: All MP6543 variants carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: Can I mix different MP6543 variants in the same production run?

A: Yes. All variants are parametrically and mechanically equivalent. However, packaging format differences (Cut Tape versus Tape & Reel) may require different handling procedures depending on your assembly process. Verify compatibility with your specific manufacturing equipment and procedures.
