MP6543GL-Z Equivalent & Substitute Parts

Part Overview

The MP6543GL-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.

Substitute parts are necessary when the primary part number becomes unavailable due to inventory constraints, supply chain disruptions, or specific packaging and delivery requirements. All substitute parts listed maintain identical electrical specifications and functional performance while differing only in packaging format (Cut Tape versus Tape & Reel) and internal device variants.

Key Parameters

Substitute Part Grouping Explanation

All substitute parts for the MP6543GL-Z share the same base product number (MP6543) and maintain identical electrical and functional specifications. 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

Physical Equivalence Criteria:

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

Regulatory Equivalence Criteria:

• RoHS3 Compliance
• REACH Unaffected status
• MSL Level 1 (Unlimited)

The substitute parts differ only in packaging format (Cut Tape versus Tape & Reel) and internal device variant designations (A or B series). These differences do not affect electrical performance or functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are manufactured by Monolithic Power Systems Inc. and maintain active product status. Each part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Selection between the MP6543GL-Z and its substitutes should be based on packaging requirements and inventory availability:

Cut Tape (CT) Packaging Options:

• MP6543GL-Z: Primary part number with highest inventory (55200 pcs)
• MP6543BGL-P: Alternative Cut Tape variant (1512 pcs)
• MP6543BGL-Z: Alternative Cut Tape variant (5514 pcs)

Tape & Reel (TR) Packaging Options:

• MP6543AGL-P: Tape & Reel variant (1149 pcs)
• MP6543AGL-Z: Tape & Reel variant (5746 pcs)
• MP6543GL-P: Tape & Reel variant (1421 pcs)

All parts are electrically and functionally equivalent for BLDC motor driver applications requiring 2A output current, 3V to 12V supply operation, and PWM control interface in a 24-QFN surface mount package.

Frequently Asked Questions (FAQ)

Q: Can MP6543AGL-P be used as a direct replacement for MP6543GL-Z?

A: Yes. Both parts are electrically and functionally equivalent. The primary difference is packaging format: MP6543GL-Z is supplied in Cut Tape (CT) while MP6543AGL-P is supplied in Tape & Reel (TR). Both deliver 2A output current, operate across 3V to 12V supply range, and are housed in identical 24-VFQFN Exposed Pad packages.

Q: What is the difference between the A and B series variants (MP6543AGL versus MP6543BGL)?

A: The A and B designations represent internal device variants within the MP6543 base product family. Both variants maintain identical electrical specifications, output current (2A), supply voltage range (3V ~ 12V), operating temperature range (-40°C ~ 125°C), and package configuration (24-QFN 3x4). No functional difference exists between these variants for circuit application purposes.

Q: Does packaging format (Cut Tape versus Tape & Reel) affect circuit performance?

A: No. Packaging format affects only component delivery and handling methods. Cut Tape (CT) and Tape & Reel (TR) packaging contain identical die and internal circuitry. Electrical performance, current delivery, voltage regulation, and thermal characteristics remain unchanged regardless of packaging format.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts, including MP6543GL-Z, MP6543AGL-P, MP6543AGL-Z, MP6543BGL-P, MP6543BGL-Z, and MP6543GL-P, are ROHS3 compliant and REACH unaffected.

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

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

Q: Can these parts be used interchangeably in production assembly?

A: Yes, provided the assembly process accommodates the packaging format. Cut Tape parts require different handling equipment than Tape & Reel parts. Once soldered to the PCB, all variants function identically in BLDC motor driver circuits.

Q: Which substitute part has the highest current inventory?

A: MP6543GL-Z maintains the highest inventory at 55200 pieces. If Cut Tape packaging is required, this part number offers the best availability. For Tape & Reel packaging, MP6543AGL-Z provides the highest inventory at 5746 pieces.
