Overview
The MP6619LGQ-Z is a fully integrated bipolar H-bridge motor driver from Monolithic Power Systems, designed for controlling brushed DC and stepper motors. It operates within a supply voltage range of 2.5V to 28V and delivers an output current of 5A. The device features a QFN-19 package suitable for surface mount installation. It supports an operating temperature range from -40°C to +125°C and includes thermal shutdown protection with a power dissipation rating of 2.5W.
Feature Summary
- Fully integrated H-bridge topology for bipolar motor control
- Supports both brushed DC and stepper motor applications
- Includes thermal shutdown protection for system reliability
Applications
- Brushed DC motor control systems
- Stepper motor drive circuits
- Industrial motion control modules
Procurement Notes
Verify the specific suffix (Z) against official MPS documentation to confirm RoHS compliance status. Ensure the QFN-19 footprint matches your PCB layout requirements. Confirm that the 5A output current capability aligns with your thermal management design, as the device specifies a 2.5W power dissipation limit under standard conditions.
Selection Notes
Select this component when a single-chip solution for bipolar motor driving is required within a 28V maximum supply constraint. The wide operating temperature range makes it suitable for industrial environments. Consider the QFN-19 package size relative to available board space and thermal pad requirements for adequate heat sinking.
Part Context
This part belongs to the MP6619 series of motor drivers from Monolithic Power Systems. It is categorized under PMIC - Motor Drivers, Controllers & Accessories. The device serves as a compact alternative to discrete MOSFET implementations, integrating high-side and low-side drivers into a single IC.
Replacement Considerations
Check for direct pin-compatible alternatives within the MPS portfolio or other manufacturers offering similar 5A H-bridge specifications in a QFN-19 package. Verify that any substitute maintains the same voltage range and thermal characteristics.
