MP6543HGL-P

Overview

The MP6543HGL-P is a three-phase power stage designed for brushless DC motor applications. It integrates three half-bridge drivers with N-channel MOSFETs, providing a continuous output current of 2A per phase. The device operates on a supply voltage range of 3V to 22V and utilizes PWM inputs for control. It features an integrated charge pump for high-side gate drive support at 100% duty cycle, automatic synchronous rectification, and a built-in 3.3V/100mA LDO regulator. Protection mechanisms include over-current protection with adjustable thresholds, under-voltage lockout, and thermal shutdown.

Feature Summary

Integrates three half-bridge drivers with N-channel MOSFETs for three-phase BLDC motor control
Supports 100% duty cycle operation via internal charge pump and trickle charging circuit
Includes automatic synchronous rectification and integrated bidirectional current sampling amplifier
Provides comprehensive protection against over-current, under-voltage, and overheating

Applications

Brushless DC (BLDC) motor drives
Three-phase power stage implementations
Motor controllers requiring PWM input control

Procurement Notes

Verify the specific suffix 'P' indicates the standard packaging configuration as documented by Monolithic Power Systems. Confirm that the component meets RoHS3 compliance standards required for your assembly process. Ensure the 24-QFN package dimensions align with your PCB footprint design. Cross-reference the datasheet for any specific handling requirements related to moisture sensitivity level 1.

Selection Notes

Select this component when a fully integrated three-phase driver with PWM interface is required. It is suitable for applications needing up to 2A continuous current per phase within a 3V to 22V supply range. Consider the integrated protections and synchronous rectification for simplified design. Verify that the QFN-24 package fits the available board space and thermal constraints.

Part Context

The MP6543 series comprises three-phase BLDC motor drivers integrating power stages and control logic. Variants like MP6543A offer independent high/low side inputs, while MP6543B supports Hall sensor inputs. The MP6543HGL-P specifically denotes the version with ENABLE and PWM inputs, housed in a 24-pin QFN package.
