MP6543HGL-B-P Equivalent & Substitute Parts

Part Overview

The MP6543HGL-B-P is a 22V, 2A three-phase power stage multiphase motor driver manufactured by Monolithic Power Systems Inc. This PMIC integrates control and power stage functionality in a 24-QFN (3x4) surface mount package, designed for brushless DC (BLDC) motor applications. The device operates across a supply voltage range of 3V to 22V with an operating temperature range of -40°C to 125°C (TJ). The MP6543HGL-B-P is currently in active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified based on matching electrical specifications, mechanical packaging, and functional characteristics within the MP6543 base product family.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts within the MP6543 family are identified based on strict parametric equivalence. All substitute parts share identical electrical specifications: 22V maximum supply voltage, 2A output current, three-phase half-bridge configuration, PWM interface, and NMOS technology. All parts operate within the same temperature range (-40°C to 125°C TJ) and are packaged in the 24-QFN (3x4) surface mount format with exposed pad.

The primary differentiator among substitute parts is the packaging format suffix:

Packaging Format Designations:

• -P suffix: Tape & Reel (TR) packaging
• -Z suffix: Cut Tape (CT) & Digi-Reel® packaging

All substitute parts maintain identical mechanical compatibility (24-VFQFN Exposed Pad), identical compliance certifications (ROHS3, REACH Unaffected), and identical regulatory classifications (EAR99, HTSUS 8542.39.0001). Substitution is valid across all parts within this family when packaging format requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are manufactured by Monolithic Power Systems Inc. and maintain active product status. Each part is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. All parts carry identical electrical and mechanical specifications, ensuring direct functional interchangeability within the MP6543 base product family.

Selection among substitute parts should be based on packaging format requirements:

Tape & Reel (TR) Format - Parts with -P suffix (MP6543HGL-B-P, MP6543HGL-A-P, MP6543HGL-P) are suitable for high-volume automated assembly processes requiring continuous reel feeding.

Cut Tape (CT) & Digi-Reel® Format - Parts with -Z suffix (MP6543HGL-A-Z, MP6543HGL-B-Z, MP6543HGL-Z) are suitable for lower-volume applications, prototyping, or mixed-component assembly scenarios.

Inventory availability varies across the product family. MP6543HGL-Z offers the highest inventory level (10,346 pcs), while MP6543HGL-B-P offers the lowest (691 pcs). Selection should account for supply chain requirements and lead time considerations.

Frequently Asked Questions (FAQ)

Q: Are all MP6543 variants electrically identical?

A: Yes. All substitute parts within the MP6543 family share identical electrical specifications: 22V supply voltage range, 2A output current, three-phase half-bridge configuration, PWM interface, NMOS technology, and -40°C to 125°C operating temperature range. Electrical interchangeability is complete.

Q: What is the difference between -P and -Z packaging suffixes?

A: The -P suffix designates Tape & Reel (TR) packaging, while the -Z suffix designates Cut Tape (CT) & Digi-Reel® packaging. Both formats contain identical die and are mechanically compatible with the same PCB footprint (24-QFN 3x4). The difference is in the delivery format and handling method during assembly.

Q: Can I substitute MP6543HGL-B-P with MP6543HGL-Z?

A: Yes. Both parts are parametrically equivalent with identical electrical and mechanical specifications. The only difference is packaging format (Tape & Reel versus Cut Tape & Digi-Reel). PCB layout and soldering processes remain unchanged.

Q: Are there any thermal or performance differences between substitute parts?

A: No. All parts operate within the identical temperature range (-40°C to 125°C TJ) and deliver identical performance characteristics. Thermal behavior and electrical performance are equivalent across all variants.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All substitute parts are ROHS3 compliant, REACH unaffected, and carry identical regulatory classifications (EAR99, HTSUS 8542.39.0001). Compliance certifications are uniform across the entire MP6543 family.

Q: Which substitute part should I select for new designs?

A: Selection should be based on packaging format requirements and inventory availability. For automated high-volume assembly, select a -P suffix part (Tape & Reel). For lower-volume or prototype applications, select a -Z suffix part (Cut Tape & Digi-Reel). All parts are equally suitable for new designs from an electrical and mechanical standpoint.

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

A: Yes. All substitute parts use the 24-VFQFN Exposed Pad package with identical mechanical dimensions, pin configuration, and thermal characteristics. PCB footprints and assembly processes are interchangeable.
