Monolithic Power Systems (MPS) EVQ6634-LTE-00A Motor Driver Evaluation Board
Monolithic Power Systems (MPS) EVQ6634-LTE-00A Motor Driver Evaluation Board is designed to demonstrate the capabilities of the MPQ6634-AEC1, a 3-phase, sensorless brushless DC (BLDC) motor driver with integrated power MOSFETs. The MPQ6634-AEC1 provides sensorless field-oriented control (FOC) to achieve improved efficiency and low vibration with up to 2A of peak current. The input voltage (VIN) range is between 4.5V and 35V.
The Monolithic Power Systems (MPS) MPQ6634-AEC1 controls the motor speed through the pulse-width modulation (PWM) signal with a 50Hz to 20kHz PWM input frequency. The device supports DC input speed control. It also provides closed-/open-loop speed control and a built-in configurable speed curve function.
