Thông số kỹ thuật
MP6530GR-Z is a wide-input three-phase BLDC pre-driver IC produced by Monolithic Power Systems. It works with six external N-channel MOSFETs to build three half-bridge circuits for driving three-phase brushless DC motors and permanent magnet synchronous motors.
Suffix Explanation
- MP6530: Main model of three-phase BLDC gate driver series
- GR: 28-pin VFQFN package with exposed thermal pad
- -Z: Tape-and-reel packing for automatic SMT mounting; -P represents tray packing
1. Main Electrical Parameters
Input Power Supply
- Operating voltage range: 5 V to 60 V DC
- Equipped with bootstrap gate drive circuit and internal charge pump, supporting 100% duty cycle operation without bootstrap voltage dropout
- Each gate channel features 0.8 A source peak current and 1 A sink peak current
Control Functions
- Independent PWM input pins for three phases plus a global enable pin, convenient for speed and direction control via main MCU
- Dead time can be set by external resistors to prevent upper and lower bridge tubes from conducting at the same time
- Overcurrent protection threshold is set by external sampling resistors with a fixed 500 mV reference voltage
- Low-power sleep mode reduces static power consumption for battery-operated devices
- Open-drain fault output pin to feed error signals back to the main control system
2. Built-in Protection Functions
- Input undervoltage lockout to avoid abnormal startup at insufficient supply voltage
- Adjustable overcurrent protection that locks output when motor stalling or overcurrent occurs
- Thermal shutdown protection which disables driving signals at excessive die temperature and recovers after temperature drops
- Bootstrap undervoltage protection for floating high-side drive power
- Hardware interlock logic to prevent shoot-through current inside each bridge arm
3. Package and Mechanical Details
- Package type: 28-pin QFN with exposed thermal pad
- Package size: 4.0 mm × 4.0 mm compact surface mount form factor
- Moisture sensitivity level MSL3, requiring reflow soldering within 168 hours after opening the sealed package
- Exposed pad improves heat dissipation during long-term high-frequency switching
4. Environment and Compliance
- Operating junction temperature range: -40 ℃ to +125 ℃
- RoHS lead-free and halogen-free compliant, conforming to REACH regulations
- Strong anti-interference capability for industrial electromagnetic complex environments
5. Typical Application
Drive boards for cordless power tools including electric drills and impact wrenches Main motor control of electric scooters and lightweight electric mobility devices Three-phase drive modules for industrial fans, water pumps and ventilation equipment Motor control units of household appliances such as vacuum cleaners and air conditioner internal fans Actuator drivers for robotic equipment and propulsion system pre-drivers of small drones Motor drive circuits of portable battery-powered automation equipment and handheld testing instruments
