Overview
The MP6545AGV-Z is a three-phase brushless DC motor driver manufactured by Monolithic Power Systems. It operates within a supply voltage range of 4.5 V to 45 V and delivers an output current of 2.5 A per phase. The device features a simple power stage architecture requiring external current measurement components. It is housed in a QFN-28 surface-mount package and supports a switching frequency up to 2 MHz. The component functions reliably across an extended temperature range from -40°C to +125°C, with a typical quiescent current of 2.8 mA.
Feature Summary
- Integrates a three-phase power stage for direct brushless DC motor control
- Supports external current sensing for precise torque management
- Includes high-side and low-side gate drivers with protection features
Applications
- Brushless DC motor drives in industrial automation
- Fan and pump control systems
- Consumer appliance motor regulation
Procurement Notes
Verify the specific suffix AGV-Z against the manufacturer's latest datasheet to confirm pinout and thermal characteristics. Ensure the design accommodates the required external current sense components as the device does not integrate internal shunt amplifiers. Confirm moisture sensitivity level handling during assembly to prevent package damage.
Selection Notes
Select this component for applications requiring moderate current levels up to 2.5 A with a wide input voltage capability. It is suitable for designs prioritizing simplicity in control loops due to the external current measurement requirement. Consider the QFN-28 footprint for PCB layout constraints and verify thermal dissipation capabilities for the intended operating environment.
Part Context
This part belongs to the MP6545A series of three-phase BLDC motor drivers. It complements other MPS solutions like the MP6541 and MP6604 by offering a dedicated mid-range current option. The series focuses on providing robust gate driving capabilities while maintaining flexibility through external sensing configurations.
Replacement Considerations
MP6545AGQKT-Z serves as a direct alternative with identical electrical specifications but utilizes a TQFN-26 package instead of QFN-28. Verify mechanical compatibility before substitution.
