EVQ6634-LTE-00A

EVQ6634-LTE-00A is an evaluation board designed to demonstrate the capabilities of the MPQ6634, a 3-phase, sensorless brushless DC (BLDC) motor driver with integrated power MOSFETs. The MPQ6634 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 MPQ6634 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. The MPQ6634 provides rotational speed detection. The rotational speed detector (the FG/RD pin) is an open-drain output. In addition to rotation speed detection, the direction is controlled via the DIR pin input.
