Overview
The MP6546GL-0000-Z is a three-phase BLDC motor driver from Monolithic Power Systems, designed for gimbal control systems. It integrates three half-bridge power stages, pre-drivers, FOC logic, and angle calculation functions. The device supports a digital interface up to 1 MHz and operates within a supply voltage range of 3.5 V to 22 V. It delivers a peak output current of 3 A and features an internal charge pump for high-side MOSFET gate driving. The component is housed in a compact QFN-20 (3 mm x 4 mm) package with an exposed thermal pad.
Feature Summary
- Integrates Field-Oriented Control (FOC) logic and angle calculation for seamless gimbal axis connection.
- Supports flexible sensor integration via linear Hall inputs or magnetic angle sensors through SPI/SSC.
- Includes comprehensive protection mechanisms such as thermal shutdown, undervoltage lockout, overcurrent, short circuit, and overvoltage protection.
Applications
- Gimbal control systems
- Three-phase BLDC motors
Procurement Notes
Verify the specific suffix Z against official MPS documentation to confirm RoHS compliance and lead time status. Check distributor availability as some listings indicate temporary supply limitations. Ensure the QFN-20 package dimensions match the design constraints. Confirm that the 1 MHz digital interface requirements align with the host microcontroller capabilities before finalizing the procurement order.
Selection Notes
Select this component when designing gimbal applications requiring integrated FOC and angle processing to reduce MCU workload. It is suitable for systems needing a single digital interface for three-axis connections. Consider the 3 A peak current capability and 22 V maximum supply voltage. The QFN-20 package offers a compact solution with improved thermal dissipation via the exposed pad.
Part Context
The MP6546 belongs to the MP6546 series of three-phase BLDC drivers by Monolithic Power Systems. It is specifically engineered for gimbal control systems, integrating power stages and control logic. The GL-0000-Z variant denotes the specific packaging and environmental compliance configuration within this product line.
Replacement Considerations
MP6546GL-0000-P is listed as an alternative packaging option for the same functional device. No other direct parameter-equivalent substitutes are documented in the provided source material.
