Overview
The MP6545AGV-P is a three-phase power stage motor driver from Monolithic Power Systems, designed for brushless DC (BLDC) and brushed DC motors. It operates within a supply voltage range of 4.5 V to 45 V and supports an output current of 2.5 A. The device features a QFN-28 package with SMD/SMT mounting style. It functions as a simple three-phase power stage with external current measurement capability. The operating temperature range spans from -40°C to +125°C, with a maximum power dissipation of 3.125 W.
Feature Summary
- Integrates a simple three-phase power stage architecture
- Supports external current measurement for precise control
- Compatible with both BLDC and brushed DC motor types
Applications
- Brushless DC motor control systems
- Brushed DC motor drivers
- Motion control applications requiring three-phase power stages
Procurement Notes
Verify the exact suffix against official MPS documentation, as the provided data references MP6545AGV-P. Confirm package type and thermal specifications match design requirements. Check humidity sensitivity levels and storage conditions prior to assembly. Ensure compatibility with external current sensing components if utilizing that feature.
Selection Notes
Select this component for applications requiring a dedicated three-phase power stage with external current sensing. Compare power dissipation limits against thermal management capabilities. Verify input voltage ranges align with system power supplies. Consider package size constraints relative to PCB layout requirements.
Part Context
This part belongs to the MP6545A series of motor drivers from Monolithic Power Systems. It is categorized under Motor / Motion / Ignition Controllers & Drivers. The series includes variants like MP6545GF-P with different packaging options such as TSSOP-28.
Replacement Considerations
MP6545GF-P offers similar electrical characteristics but utilizes a TSSOP-28 package instead of QFN-28. Verify pinout compatibility and thermal performance differences before substitution.
