MP6619LGQ-Z Equivalent & Substitute Parts

Part Overview

The MP6619LGQ-Z is a bipolar motor driver integrated circuit manufactured by Monolithic Power Systems Inc., classified as a Power Management PMIC. This fully integrated H-bridge motor driver combines control and power stage functionality in a single 19-QFN (3x3) surface mount package. The device operates across a supply voltage range of 2.8V to 5.5V and supports load voltages from 2.5V to 28V, delivering up to 5A output current. The MP6619LGQ-Z is actively produced and widely used in general-purpose brushed DC and bipolar stepper motor applications. Substitute parts are identified when inventory constraints, lead time requirements, or supply chain disruptions necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP6619LGQ-Z are identified based on strict electrical and mechanical parameter matching. The substitution logic is based on the following critical parameters that must remain constant across all equivalent devices:

Electrical Parameters:

• Output current rating: 5A
• Supply voltage range: 2.8V ~ 5.5V
• Load voltage range: 2.5V ~ 28V
• Operating temperature range: -40°C ~ 125°C (TJ)
• Motor driver function: Fully integrated control and power stage
• Output configuration: Half Bridge (2)
• Interface type: PWM
• Technology: NMOS

Mechanical Parameters:

• Package type: 19-VFQFN
• Supplier device package: 19-QFN (3x3)
• Mounting type: Surface Mount

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Product Status: Active

All substitute parts must match these parameters exactly. Variations in any of these specifications disqualify a part from substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

The MP6619LGQ-P is a direct parametric equivalent to the MP6619LGQ-Z. Both devices are manufactured by Monolithic Power Systems Inc. and share identical electrical specifications, mechanical packaging, and compliance certifications. The primary distinction between these parts is packaging format designation, which does not affect functional performance or pin compatibility.

Selection Criteria:

Both parts are classified as Active products, indicating ongoing manufacturing support and availability. Both maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for industrial and commercial applications. The identical MSL rating of 1 (Unlimited) indicates equivalent moisture handling requirements during storage and assembly.

Selection between MP6619LGQ-Z and MP6619LGQ-P should be based on current inventory availability and supply chain lead times. Current inventory shows MP6619LGQ-Z at 5872 pieces and MP6619LGQ-P at 1135 pieces. Either part is suitable for direct substitution in applications requiring a 5A bipolar motor driver with PWM control interface operating across 2.8V to 5.5V supply and 2.5V to 28V load voltage ranges.

Frequently Asked Questions (FAQ)

Q: Can MP6619LGQ-P be used as a direct replacement for MP6619LGQ-Z?
