MP6543AGL-P Equivalent & Substitute Parts

Part Overview

The MP6543AGL-P is a multiphase motor driver NMOS PWM integrated circuit manufactured by Monolithic Power Systems Inc. This Power Management (PMIC) device functions as a fully integrated control and power stage for brushless DC (BLDC) motor applications. The part is classified as Active product status and is RoHS3 compliant with REACH unaffected designation. Substitute parts are necessary when the primary part number becomes unavailable due to inventory constraints, supply chain disruptions, or packaging format requirements for specific manufacturing processes.

Key Parameters

Substitute Part Grouping Explanation

All substitute parts for the MP6543AGL-P share identical electrical and mechanical specifications. Substitution is determined by the following key parameters that remain constant across all variants:

• Output Configuration: Half Bridge (3)
• Current - Output: 2A
• Voltage - Supply: 3V ~ 12V
• Operating Temperature: -40°C ~ 125°C (TJ)
• Package / Case: 24-VFQFN Exposed Pad
• Supplier Device Package: 24-QFN (3x4)
• Technology: NMOS
• Interface: PWM
• Function: Driver - Fully Integrated, Control and Power Stage
• Motor Type Support: Brushless DC (BLDC), Multiphase

The substitute parts differ only in packaging format (Tape & Reel versus Cut Tape) and suffix designation. These differences do not affect electrical performance or functional compatibility in circuit design. The suffix designations (AGL, BGL, GL) and packaging codes (P for Tape & Reel, Z for Cut Tape) represent manufacturing and distribution variants of the same base product MP6543.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with current manufacturing standards. Selection between equivalent variants should be based on the following criteria:

Packaging Format Selection:

• Tape & Reel (TR) format (suffix P): MP6543AGL-P, MP6543GL-P. Suitable for high-volume automated assembly processes requiring continuous reel feeding.
• Cut Tape (CT) format (suffix Z): MP6543AGL-Z, MP6543BGL-P, MP6543BGL-Z, MP6543GL-Z. Suitable for lower-volume production, prototyping, or manual assembly operations.

Inventory Availability: MP6543GL-Z maintains the highest inventory level at 55,200 pieces, providing maximum supply assurance. MP6543AGL-P and MP6543GL-P offer Tape & Reel packaging with moderate inventory levels (1149 and 1421 pieces respectively).

Compliance Certification: All variants carry identical REACH unaffected status and ROHS3 compliance certification, eliminating compliance-based differentiation in part selection.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are electrically and functionally identical. The difference is packaging format: MP6543AGL-P is supplied in Tape & Reel format while MP6543AGL-Z is supplied in Cut Tape format. Selection depends on assembly equipment compatibility and production volume requirements.

Q: What is the difference between the suffix designations (AGL, BGL, GL)?

A: The suffix designations represent manufacturing variants within the MP6543 base product family. All variants maintain identical electrical specifications, output current (2A), supply voltage range (3V ~ 12V), and operating temperature range (-40°C ~ 125°C). These designations do not indicate functional or performance differences.

Q: Are all substitute parts suitable for BLDC motor driver applications?

A: Yes. All listed substitute parts are rated for Brushless DC (BLDC) motor applications with multiphase support. Each part provides three half-bridge outputs with 2A per phase capability and PWM interface control.

Q: What packaging format should be selected for high-volume manufacturing?

A: Tape & Reel (TR) format parts (MP6543AGL-P, MP6543GL-P) are optimized for high-volume automated assembly. Cut Tape (CT) format parts are suitable for lower volumes or manual assembly processes.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. All substitute parts carry MSL (Moisture Sensitivity Level) rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can these parts be used interchangeably in circuit design without PCB modifications?

A: Yes. All substitute parts use identical 24-VFQFN Exposed Pad package with 24-QFN (3x4) footprint. No PCB layout or schematic modifications are required when substituting between any of these part numbers.

Q: Which substitute part offers the best supply availability?

A: MP6543GL-Z offers the highest inventory level at 55,200 pieces. This variant is available in Cut Tape format and maintains all electrical and functional specifications identical to other variants.
