The EV6634-LTE-00A is an evaluation board designed to demonstrate the capabilities of the MP6634, a three-phase, sensorless, brushless DC (BLDC) motor driver with integrated power MOSFETs. The MP6634 provides sensorless field-oriented control (FOC) to achieve improved efficiency and low vibration, with up to 2A of peak current. The input voltage (V_IN) range is between 4.5V and 35V.

The MP6634 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 open-loop/closed-loop speed control and a built-in configurable speed curve function.

The MP6634 features rotational speed detection. The rotational speed detector is an open-drain output via the FG/RD pin. The motor direction is controlled via the DIR pin.

Rich protection features include input over-voltage protection (OVP), under-voltage lockout (UVLO), locked-rotor protection, phase-loss protection, over-current protection (OCP), and thermal shutdown.

The MP6634 is available in a TQFN-12 (3mmx4mm) package with wettable flanks.
