Overview
The MP6540HGU-A-P is a three-phase power stage designed for brushless DC motor controllers. It operates within a supply voltage range of 5.5 V to 35 V and delivers an output current of 3 A. The device features a half-bridge topology with high-side and low-side inputs, housed in a QFN-26 package. It supports surface mount installation and functions reliably across temperatures from -40°C to +125°C.
Feature Summary
- Integrates three half-bridges with N-channel power MOSFETs for direct motor drive
- Supports independent high-side and low-side control inputs for flexible commutation
- Includes internal charge pump to enable 100% duty cycle operation
- Provides integrated bidirectional current sampling amplifier outputs
Applications
- Brushless DC (BLDC) motor control systems
- Industrial motion control applications
- Automotive ignition and driver circuits
Procurement Notes
Verify the specific suffix 'A' indicates the variant with high-side and low-side inputs rather than PWM/ENBL inputs. Confirm the maximum supply voltage rating of 35 V aligns with system requirements, as other variants support higher voltages. Ensure thermal management design accounts for the specified power dissipation limits in the target application environment.
Selection Notes
Select this component when independent high-side and low-side control signals are required instead of standard PWM inputs. Consider the 3 A continuous current capability and 35 V maximum voltage limit against load demands. Evaluate the QFN-26 package size for space constraints and verify PCB layout capabilities for thermal dissipation given the integrated power stage architecture.
Part Context
This part belongs to the MP6540 series of monolithic three-phase power stages by Monolithic Power Systems. It integrates pre-drivers, gate drive power supplies, and current sensing amplifiers into a single compact solution. The series is categorized under PMIC and motor drivers, offering a complete alternative to discrete MOSFET implementations.
Replacement Considerations
MP6540AGU-P and MP6540AGU-Z share the same 35 V / 3 A specifications and HS/LS input configuration. MP6540HGU-P and MP6540HGU-Z offer higher voltage ratings but utilize different input logic (PWM/ENBL). Verify input compatibility before substituting.
