MP6619LGQ-P Equivalent & Substitute Parts

Part Overview

The MP6619LGQ-P is a bipolar motor driver integrated circuit manufactured by Monolithic Power Systems Inc., classified as a Power Management (PMIC) component. This device functions as a fully integrated H-bridge motor driver with control and power stage capabilities, designed for brushed DC and bipolar stepper motor applications. The part operates across a supply voltage range of 2.8V to 5.5V with load voltage support from 2.5V to 28V, delivering 5A output current. The MP6619LGQ-P is currently in active product status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications, mechanical packaging, and functional characteristics align with the original component, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP6619LGQ-P are identified based on strict equivalence across the following critical parameters:

Electrical Specifications: Output current rating (5A), supply voltage range (2.8V ~ 5.5V), load voltage range (2.5V ~ 28V), and operating temperature range (-40°C ~ 125°C).

Functional Characteristics: Motor driver classification with fully integrated control and power stage, half-bridge output configuration (2), PWM interface, and NMOS technology.

Motor Support: Bipolar stepper motor and brushed DC motor compatibility.

Mechanical & Packaging Requirements: 19-QFN (3x3) package footprint, surface mount mounting type, and tape & reel packaging format.

Compliance & Regulatory: ROHS3 compliance, MSL 1 rating, and REACH unaffected status.

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. No deviations in electrical performance, package dimensions, or functional capability are permitted for substitute classification.

Parameter Comparison

Engineering Selection Recommendations

The MP6619LGQ-Z is a direct parametric equivalent to the MP6619LGQ-P. Both components share identical electrical specifications, functional characteristics, package footprint, and regulatory compliance status. Selection between these parts is based on availability and supply chain considerations rather than technical performance differences.

Both parts maintain active product status with Monolithic Power Systems Inc., ensuring continued manufacturer support and supply reliability. ROHS3 compliance and REACH unaffected status confirm regulatory alignment for applications requiring environmental and hazardous substance restrictions.

The 19-QFN (3x3) surface mount package is consistent across both parts, enabling direct PCB layout compatibility without design modification. MSL 1 rating indicates unlimited shelf life under standard storage conditions, reducing moisture-related handling constraints.

For applications requiring 5A output current delivery across 2.5V to 28V load voltage ranges with PWM-controlled bipolar stepper or brushed DC motor drive, either part satisfies the functional and electrical requirements without compromise.

Frequently Asked Questions (FAQ)

Q: Can MP6619LGQ-Z replace MP6619LGQ-P in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output current rating, voltage ranges, operating temperature, package footprint, and compliance certifications. Direct substitution is supported without circuit modification.

Q: Are there differences in motor control capability between these parts?

A: No. Both parts provide identical motor driver functionality: fully integrated control and power stage, half-bridge output configuration, PWM interface, and support for bipolar stepper and brushed DC motor types.

Q: Do these parts require different PCB layouts?

A: No. Both parts use the 19-QFN (3x3) surface mount package with identical pin configuration and footprint. PCB layout remains unchanged during substitution.
