Overview
The MP6546GL-0000-P 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, Field Oriented Control (FOC) logic, and angle calculation functions. The device supports a digital interface up to 1 MHz Fast Mode and accepts linear Hall sensor inputs via HA/HB or magnetic angle sensors via SPI/SSC. It features an internal charge pump for high-side MOSFET gate drive and includes protection mechanisms such as thermal shutdown, under-voltage lockout, over-current, short-circuit, and over-voltage protection. Operating voltage ranges from 3.5 V to 22 V with a peak output current of 3 A.
Feature Summary
- Integrates FOC logic and angle calculation for seamless gimbal axis connection
- Supports flexible sensor integration including linear Hall and magnetic angle sensors
- Includes built-in protection against thermal, voltage, and current faults
Applications
- Gimbal control systems
- Three-phase BLDC motor drives
Procurement Notes
Verify the specific suffix 'P' against the manufacturer's official datasheet to confirm packaging configuration and availability status. Cross-reference the full part number MP6546GL-0000-P with MPS documentation to ensure compatibility with system requirements. Confirm RoHS compliance and moisture sensitivity levels prior to procurement.
Selection Notes
Select this component for applications requiring integrated FOC and angle processing to reduce MCU load. Ensure the input signal matches supported interfaces: linear Hall sensors via HA/HB or magnetic sensors via SPI/SSC. Verify that the supply voltage remains within the 3.5 V to 22 V range and that peak current demands do not exceed 3 A.
Part Context
This part belongs to the MP6546 series of three-phase BLDC drivers. It is distinct from other MPS motor drivers like the MP6543, which offers different current ratings and interface options. The MP6546 series is specifically optimized for gimbal applications with integrated angle computation capabilities.
Replacement Considerations
MP6543CGL-P is listed as a parameter equivalent replacement for the discontinued MP6543CGL-Z. However, direct substitution between MP6546 and MP6543 families requires verification of pinout and functional differences.
