MPQ6634-AEC1 Sensorless BLDC Motor Driver
Monolithic Power Systems (MPS) MPQ6634-AEC1 Sensorless BLDC Motor Driver is a 3-phase, sensorless brushless DC (BLDC) motor driver with integrated power MOSFETs. It features sensorless field-oriented control (FOC) for improved efficiency and low vibration, with up to 2A of peak current. The input voltage (VIN) ranges between 4.5V and 35V. The MPQ6634-AEC1 controls the motor speed through the pulse-width modulation (PWM) signal with a PWM input frequency between 50Hz and 20kHz. The device also supports DC input speed control.
