MP6543HGL-A-Z Equivalent & Substitute Parts

Part Overview

The MP6543HGL-A-Z is a fully integrated multiphase motor driver PMIC manufactured by Monolithic Power Systems Inc., designed for brushless DC (BLDC) motor applications. This three-phase power stage integrates control and power delivery in a single 24-QFN package, operating across a 3V to 22V supply range with 2A output current capability. The device is Active product status and ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified based on matching electrical specifications, mechanical packaging, and functional integration. Alternative part numbers within the MP6543 base product family provide identical performance parameters while differing in packaging format or manufacturing lot designations.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the MP6543 family is determined by electrical and mechanical parameter equivalence. All substitute parts share identical specifications across the following critical parameters:

Electrical Equivalence Criteria:

• Output current rating: 2A
• Supply voltage range: 3V ~ 22V
• Operating temperature range: -40°C ~ 125°C (TJ)
• Output configuration: Half Bridge (3)
• Interface protocol: PWM
• Technology platform: NMOS

Mechanical Equivalence Criteria:

• Package type: 24-VFQFN Exposed Pad
• Supplier device package: 24-QFN (3x4)
• Mounting type: Surface Mount

Compliance Equivalence:

• RoHS3 compliance
• REACH unaffected status
• MSL 1 rating

Variations between substitute parts are limited to packaging format (Tape & Reel versus Cut Tape & Digi-Reel) and manufacturing lot designations (suffix letters A, B, or Z). These variations do not affect electrical performance or functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts within the MP6543 family are electrically and mechanically equivalent to the MP6543HGL-A-Z. Selection between equivalent parts is based on the following engineering considerations:

Packaging Format Selection:

• Tape & Reel (TR) format (MP6543HGL-A-Z, MP6543HGL-A-P, MP6543HGL-B-Z, MP6543HGL-P): Suitable for high-volume automated assembly processes requiring continuous reel feeding.
• Cut Tape & Digi-Reel format (MP6543HGL-Z): Suitable for lower-volume applications, prototyping, or mixed-component pick-and-place operations.

Compliance Status: All substitute parts maintain identical compliance certifications: ROHS3 compliant, REACH unaffected, and MSL 1 rating. No compliance restrictions apply to any substitution within this family.

Product Status: All parts are Active status, ensuring continued manufacturing support and availability.

Inventory Availability: Part selection may be influenced by current stock levels. MP6543HGL-Z maintains the highest inventory (10,346 pcs), while MP6543HGL-A-P maintains the lowest (1,545 pcs).

Frequently Asked Questions (FAQ)

Q: Are all MP6543 variants electrically interchangeable?

A: Yes. All substitute parts (MP6543HGL-A-P, MP6543HGL-B-Z, MP6543HGL-P, MP6543HGL-Z) share identical electrical specifications including 2A output current, 3V to 22V supply range, -40°C to 125°C operating temperature, and three-phase half-bridge output configuration. Direct substitution in circuit design is supported without modification.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel (TR) format supplies components on continuous reels optimized for automated high-speed assembly equipment. Cut Tape & Digi-Reel format supplies components on cut tape segments or alternative reel formats, suitable for lower-volume production or manual assembly processes. Electrical and mechanical specifications remain identical.

Q: Can I substitute MP6543HGL-Z for MP6543HGL-A-Z in production?

A: Yes. Both parts are electrically equivalent with identical performance specifications. The primary difference is packaging format: MP6543HGL-Z uses Cut Tape & Digi-Reel format while MP6543HGL-A-Z uses Tape & Reel format. Assembly equipment compatibility should be verified based on your specific pick-and-place system requirements.

Q: Do all MP6543 variants meet the same compliance standards?

A: Yes. All substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity) rating. No compliance differences exist between variants.

Q: What does the suffix letter (A, B, or Z) in the part number indicate?

A: Suffix letters represent manufacturing lot designations and do not indicate functional or electrical differences. All variants with different suffixes are electrically and mechanically equivalent.

Q: Is the 24-QFN (3x4) package identical across all variants?

A: Yes. All substitute parts use the 24-VFQFN Exposed Pad package with 24-QFN (3x4) supplier device package designation. PCB footprint and pin configuration are identical across all variants.

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

A: Yes. All variants are electrically and mechanically equivalent, supporting mixed-lot assembly without functional impact. Packaging format differences (Tape & Reel versus Cut Tape & Digi-Reel) may require separate handling in automated assembly processes.
