MP6543BGL-Z Equivalent & Substitute Parts

Part Overview

The MP6543BGL-Z is an active, fully integrated multiphase motor driver PMIC manufactured by Monolithic Power Systems Inc. This component functions as a three-phase power stage with integrated control and power delivery for brushless DC (BLDC) motor applications. The device operates across a 3V to 12V supply range with 2A output current capability and is housed in a 24-QFN (3x4) surface mount package with exposed pad.

Substitute parts are necessary when the primary part number becomes unavailable due to inventory constraints, supply chain disruptions, or packaging format requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

All substitute parts for the MP6543BGL-Z share identical electrical and mechanical specifications across the following critical parameters:

Electrical Specifications:

• 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 Specifications:

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

Compliance & Regulatory:

• RoHS3 Compliant
• REACH Unaffected
• MSL: 1 (Unlimited)

Packaging Format Variations: Substitute parts differ only in packaging format (Cut Tape vs. Tape & Reel) and internal die revision designations (A vs. B series, GL vs. AGL vs. BGL). These variations do not affect electrical performance or functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full parametric equivalence to the MP6543BGL-Z across electrical performance, thermal characteristics, and mechanical form factor. Selection among these alternatives is determined by packaging and supply requirements:

Cut Tape (CT) Format:

• MP6543BGL-Z: Primary specification
• MP6543BGL-P: Alternative die revision, Cut Tape format
• MP6543GL-Z: Alternative die revision, Cut Tape format, highest inventory availability (55,200 units)

Tape & Reel (TR) Format:

• MP6543AGL-P: Alternative die revision, Tape & Reel format
• MP6543AGL-Z: Alternative die revision, Tape & Reel format
• MP6543GL-P: Alternative die revision, Tape & Reel format

All parts are ROHS3 compliant, REACH unaffected, and carry active product status. Die revision designations (A, B, or unmarked) and packaging designations (P or Z suffix) do not affect functional compatibility or electrical performance in BLDC motor driver applications.

Frequently Asked Questions (FAQ)

Q: Can MP6543GL-Z be used as a direct replacement for MP6543BGL-Z?

A: Yes. Both parts share identical electrical specifications (2A output, 3V-12V supply, -40°C to 125°C operating range), mechanical packaging (24-VFQFN Exposed Pad, 24-QFN 3x4), and compliance certifications (ROHS3, REACH Unaffected). The difference is the die revision designation and packaging format. MP6543GL-Z is available in Cut Tape format with significantly higher inventory (55,200 units).

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape and Tape & Reel are packaging and delivery formats only. Both contain identical components in the same 24-VFQFN package. Cut Tape is supplied in individual strips, while Tape & Reel is supplied on continuous reels for automated assembly. Electrical and mechanical specifications are identical.

Q: Are the A, B, and unmarked die revisions (AGL, BGL, GL) functionally equivalent?

A: Yes. All die revision designations (A, B, or unmarked) are functionally equivalent for BLDC motor driver applications. They share identical electrical performance, output current (2A), supply voltage range (3V-12V), operating temperature range (-40°C to 125°C), and package specifications.

Q: Which substitute part has the best availability?

A: MP6543GL-Z offers the highest inventory availability at 55,200 units in stock, supplied in Cut Tape format with identical electrical and mechanical specifications to the MP6543BGL-Z.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, meeting the same regulatory and environmental standards as the MP6543BGL-Z.

Q: Can I mix packaging formats (Cut Tape and Tape & Reel) in the same assembly?

A: Yes. Both packaging formats contain identical components in the same 24-VFQFN package. Mixing formats is permissible from an electrical and mechanical standpoint, though manufacturing processes may require separate handling procedures.

Q: What is the Moisture Sensitivity Level (MSL) for all substitute parts?

A: All substitute parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
