Overview
The MP6543CGL-P is a three-phase brushless DC motor driver from Monolithic Power Systems. It integrates a 22V, 1.2A power stage with ENABLE and PWM inputs for each half-bridge. The device operates on a supply voltage range of 3V to 22V and supports an output current of 1.2A. It functions within a temperature range of -40°C to +125°C TJ. The component utilizes a QFN-24 package (3mm x 4mm) with a thermal pad for surface mount installation. Maximum power dissipation is rated at 2.6W.
Feature Summary
- Integrates three half-bridges driven by six N-channel power MOSFETs
- Includes internal charge pump supporting 100% duty cycle operation
- Features automatic synchronous rectification functionality
- Provides adjustable over-current protection thresholds
Applications
- Brushless DC motor control systems
- Motion control applications
- General purpose motor drivers
Procurement Notes
Verify the specific suffix 'P' against official MPS documentation to confirm availability status and lead times. Check RoHS compliance details in the datasheet. Confirm package dimensions match design requirements. Ensure thermal management solutions align with the 2.6W power dissipation rating. Validate that ENABLE and PWM input interfaces meet system logic levels.
Selection Notes
Select this component when a fully integrated three-phase BLDC driver with low current requirements is needed. The MP6543CGL-P offers a compact QFN-24 footprint suitable for space-constrained designs. Consider its 1.2A continuous output capability and 22V maximum voltage rating. Evaluate the need for ENABLE/PWM control interfaces versus other variants like MP6543A or B which offer different input configurations.
Part Context
The MP6543CGL-P belongs to the MP6543 series of three-phase BLDC motor drivers. This family includes variants such as MP6543A with independent high/low side inputs and MP6543B with Hall element inputs. All share similar core integration features including pre-drivers, gate drive power supplies, and current sampling amplifiers within the same 24-pin QFN package.
Replacement Considerations
MP6543CGL-Z is listed as a parameter-equivalent substitute but is marked as obsolete. Verify if MP6543CGL-P is available as a direct replacement for discontinued Z-suffix units. Cross-reference pinouts and electrical specifications before substitution.
